Function Description of SW50
Parallel connection of the BIC-2200 is by digital differential signals. Units in parallel compensate and stabilize their output through the digital parallel signals. SW50 is a termination resistor which is used to prevent signal reflections, then increasing communication quality For the usage of SW50, please refer.S to 5.9 Current haring.

Function Description of DIP Switch
Each unit should have their unique and own device address to communicate over CANBus. Please be aware that: This DIP switch only takes effect when the communication interface is used. It is not necessary to set this switch in general use. For details, please refer to 5.10.2 CANBus addressing.

Operation

BIC-2200 possesses AC to DC and DC to AC two way conversion functions. The conversion direction can be automatically detected and controlled by BIC-2200’s internal firmware or manually switched by users according to different application requirements. Before entering detailed function explanation. Please refer to following definitions. AC to DC (Energy absorbing and charging/ power supplying):
The BIC-2200 converts AC energy from the grid into DC energy for the battery or the loads. The operation principle is the same as an ordinary power supply or a charger.

DC to AC (Energy recycling and discharging):
Opposite to the AC to DC conversion, the BIC-2200 converts DC energy from the battery or loads into AC energy, then feeding back to the grid. AC output synchronization range is 180Vac~264Vac/47Hz~63Hz, the bidirectional power supply can work normally as long as the AC gird is within the range.

Description of Bidirectional Operation

Overview
The output range of the BIC-2200 covers DC: 10V – 112V; AC: 180 – 264Vac / 47-63Hz, which can be used to applications with various voltage requirements, such as battery test equipment. To cope with different application occasions, there are two modes for selection, bi-direction auto-detect mode and programmable bi-direction battery mode.

Bi-direction auto-detect mode
This is the default factory setting, AC to DC or DC to AC conversion is controlled by BIC-2200 automatically according to operation mechanism below.

• “Target voltage” is the DC voltage setting of the bidirectional supply, when the DC end voltage is different from the “target voltage”, the internal firmware will switch between two conversion functions of AC to DC or DC to AC. “Target voltage” is adjustable by the SVR.
• When the “target voltage” is higher than the battery voltage or application equipment voltage, the BIC-2200 operates in AC to DC conversion.
• When the “target voltage” is lower than the battery voltage or application equipment voltage, the BIC-2200 operates in DC to AC conversion.
  NOTE: During this mode, AC to DC or DC to AC conversion is judged by the internal firmware. Active control signal (e.g. C/D control) will not take effect in this mode.

Bi-direction battery mode
This option only works with the CANBus model, and with its communication interface. To activate the mode, please follow below:

1. Set command SYSTEM_CONFIG(0x00C2) at 0x0003 → Activate CANBus communication mode.
2. Set command BIDIRECTIONAL_CONFIG(0x00C2) at 0x0001 → Set at bi-direction battery mode.
3. Repower on the supply to activate the battery mode
   NOTE: For detailed CANBus information, please refer to 5.10 CANBus Protocol

After bi-direction battery mode is activated, users can switch the supply between AC to DC or DC to AC conversion by CANBus command (digital) or C/D control (analogy). Please refer to 5.1.3.1 CANBus command (digital) and 5.1.3.2 C/D control (analogy)

CANBus command (digital)
The users can set the supply in AC to DC (charging) or DC to AC (discharging) conversion directly through command DIRECTION_CTRL (0x0100). Command VOUT_SET(0x0020) and IOUT_SET(0x0030) are used to adjust values of charge voltage and charge current in AC to DC conversion. Command REVERSE_VOUTSET(0x0120) REVERSE IOUT_SET(0x0130) are used to adjust values of discharging voltage and discharging current in DC to AC conversion.

NOTE: Please refer to 5.10.4 CANBus value range and tolerance for detailed information about adjustable ranges of VOUT_SET, IOUT_SET, REVERSE_VOUT_SET and REVERSE_IOUT_SET.

C/D Control (analogy)
The users also can control AC to DC (charging) or DC to AC (discharging) conversion via analogy signals. NOTE: Analogy signals cannot be used to adjust parameters of charging voltage VOUT(_SET)/discharging voltage (REVERSE VO_UT SET_a)nd charging current IOUT(_SET)/discharge current R(EVERSEIOUT SET)but, only control AC to DC or DC to AC conversion.

Notes on battery mode
In bi-direction battery mode, although users can determine direction of the conversions on their demand, however if the setting voltage does not match the actual DC end voltage, AC to DC (charging) or DC to AC (discharging) conversion may not work as expected. Here are examples that will cause conversion errors.

1. During AC to DC conversion (C/D control = High or DIRECTION_CTRL = 00h), if battery voltage is higher than the value of command VOUTSET (charge voltage), the BIC-2200 will perform DC to AC conversion instead, but limiting discharge current at 5% of rated current. If you want to ensure AC to DC conversion working properly, please make sure value of command VOUT SET is higher than the battery voltage.
2. During DC to AC conversion (C/D control =Low or DIRECTION_CTRL = 01h), if battery voltage is lower than the value of command VOUT_SETREV, the BIC 2200 will perform AC to DC conversion instead, but then limiting charge current at 5% of rated current. To ensure DC to AC conversion working properly, please make sure value of command VOUT SET_REV is lower than the battery voltage.

Inrush Current Limiting

• Built-in AC inrush current limiting circuit
• Since the inrush current limiting circuit mainly consists of a NTC thermistor and a relay, inrush current will be much higher than the specified value if the thermistor in AC side is not allowed sufficient time to cool down. After turning off the supply, a 10 second cool down period is recommended before turning on again.

Power Factor Correction (PFC)
Built-in active power factor correction (PFC) function, power factor (PF) will be 0.95 or better at full load condition in AC to DC or DC to AC conversion. PF will be less than 0.95 if it is not at full load condition during AC to DC or DC to AC conversion.

Fan Speed control
Built-in fan speed control circuit, fan speed changes automatically depending on internal temperature.

Fault Signal

• Fault signal is used to inform application equipment that whether it is energy recyclable. When it is OLP, SCP or OTP, BIC-2200 will send a high level of fault signal 100ms in advance to notify the application before shutting down the supply. A fault signal will send out at the same time of shutting down operation in the reset of protection (e.g. AC_fail).
• Maximum output current 4mA.

DC(-OK)Signal

• Built-in DC output voltage detection circuit.
• Maximum output current 4mA.

Remote Control

• Built-in remote ON/OFF control circuit, which is used to turn on/off the supply.
• Please be aware that remote ON/OFF and““+5V-AUX on CN46”should be linked together to allow the unit to operate normally; if kept open, there will be no output.
• Maximum input voltage 5.5V.

Auxiliary Output
Built-in 12V/0.5A auxiliary output

Parallel Operation
BIC-2200 has the built-in active current sharing function and can be connected in parallel, up to 5 units, to provide higher output power as exhibited below:

• The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
• In parallel connection, power supply with the highest output voltage will be the master unit and its Vout will be the DC bus voltage.
• The total output current must not exceed the value determined by the following equation: Maximum output current at parallel operation=(Rated current per unit)(Number of unit)xx0.95
• When the total output current is less than 5% of the total rated current, or say (5% of Rated current per unit) x (Number of unit) the current shared among units may not be balanced.
• Under parallel operation ripple of the output voltage may be higher than the SPEC at light load condition, It will go back to normal ripple level once the output load is more than 5%.

Note:
The conversion of setting and reading values is defined as following:
Actual value = Communication reading value × Factor (F value). Among them, Factor needs to refer to the definition of SCALING_FACTOR in each model list. EX: VDC_real (actual DC voltage) = READ_VOUT x Factor.

Protections and Trouble Shooting

Protections

Anti-islanding Protections
BIC-2200 is designed to refer to IEC 62116(2008), the supply shuts off within 2 seconds when AC is cut or abnormal. Please be aware that it is necessary to install an AC circuit breaker that complies with grid-tie standard in your country before the supply.

Over Temperature Protection (OTP) and Alarm
Built-in thermal detection circuit, once the internal temperature exceeds a threshold value, the supply will shut down automatically (the fans will still be running to cool down the supply). Please switch off the supply, remove all possible causes and then leave the supply cooling down to a normal working temperature (approximate 10 minutes – 1 hour) before repower on again. Maximum output current 4mA. AC Fail Protection
When AC voltage/frequency is abnormal, BIC-2200 will enter protection mode to prevent damaging itself or affect quality of the grid no matter which conversion it is, D/A or A/D. The supply will restore automatically when AC voltage/frequency back to normal.

Short Circuit Protection
When there is short circuit at AC/DC end of BIC-2200, the supply will enter protection mode and shut down. Repower on to restore after short-circuit condition is resolved.

Over Current Protection
In AC to DC conversion, when the load current exceeds 110%±5%of the rated current, protection mode will be triggered. Repower on to restore after over- current condition is resolved.

DC Over Voltage Protection
When the DC end voltage is too high, the DC over-voltage protection circuit will be triggered. Repower on to restore after over-voltage condition is resolved.

Trouble Shooting

Remote OFF

| Make sure remote ON/OFF is connected to +5V
AC/DC or DC/AC conv er sion is incorrect| The setting voltage doesn’t match actual DC end voltage| If it is bi-direction auto-detect mode, please refer to 5.1.2. If it is bi-direction battery mode, please refer to 5.1.3.3

LED shows abnormal indication

| The ambient temperature too high| Re-start the supply after temperature dropped back
DC load current too high| Re-start the supply after reducing DC load current

AC voltage/frequency abnormal

| Re-start the supply after AC voltage/frequency is within a normal range

Battery or load voltage too high

| Re-start the supply after DC end voltage is within a normal range
