Remarks

• The number of drives mounted under different MCBs in the table is the maximum value. Please do not exceed this number during installation.
• Calculation uses typical values from ABB series S200 as a reference.
• Different brands and models of miniature circuit breakers, the number of drives mounted will be slightly different.
• If the ambient temperature of the MCB installation exceeds 30°C or multiple MCBs are installed side by side, the number of drives mounted will be reduced and the calculation needs to be recalculated.
• Electrician’s usually consider Type B for household lighting and Type C for commercial lighting applications.

Functions

• Output short-circuit behavior
• In case of a short-circuit at the LED output, the LED output is switched off.
• After restart of the LED driver, the output will be activated again.

Output no-load operation

• The LED driver will not be damaged in no-load operation.
• The output will be deactivated and is therefore free of voltage.
• If a LED load is connected , the device has to be restarted before the output will be activated again.

Output overload protection

• If the output voltage range is exceeded the LED driver turns off the LED output.
• After restart of the LED driver the output will be activated again.

Output hot plug-in

• For protection LED if plug the LED into the output of the powered driver,  the LED will not on, the device has to be restarted.

Driver restart method

• There are two ways to restart the device:
• Through the AC input port: disconnect the AC of the driver and power it again.
• Through dimming interface.
• DALI: send the “OFF” command first, then send the “MAX” command.

Adjustable output current (AOC)

• The output current of the driver can be adjusted within a certain range, and 2 options can be selected through the device configuration software.
• Setting 1 (default): DIP-switch
• The output current is determined by the selection of the DIP-switch.
• Setting 2: Programming
• The output current is determined by the programming setting.

Constant light output (CLO)

• The luminous flux of a LED decreases constantly over the life-time.
• The CLO function ensures that the emitted luminous flux remains stable.For that purpose the LED current will increase continuously over the LED life-time.
• In device configuration it is possible to select a start value(in percent) and an expected life-time.The LED Driver adjusts the current afterwards automatically.

Emergency lighting(EL)

• The driver works normally under DC input.

• When the driver is applied in DC input, the positive pole of the DC cable
  should be connected to the ACL/DC+ terminal, and the negative pole of the DC cable should be connected to the ACN/DC- terminal. If the connection is reversed, the driver will not be damaged, but it will affect the EL function normal work.

• The output response action after DC input can be set through device configuration software.

• Setting (default): When DC input, the output of the driver remains unchanged, and the dimming function responds normally.

• Setting: When DC input, the output of the driver jumps to the set brightness, and the dimming function is invalid.
