PRODUCT DESCRIPTION

The ICT DIN Power Supply with integrated battery charging and low voltage disconnect provides 360 watts of 48- or 24volt DC output. It features wide- ranging AC input, low-noise emissions, temperature-compensated charging, adjustable charge current, and Form C alarm contacts.
The power supply can be paired with the ICT DIN Power Distribution Unit (ICT- DINPDU6) to allow remote monitoring of voltage, current, temperature and alarms over Ethernet.
Features include:

• Wide-range Power Factor corrected AC input supports operation worldwide.
• Dedicated independently controlled backup battery port with LVD relay.
• Adjustable battery charge current to accommodate lower capacity batteries.
• Floating Form-C alarm contact output supports remote monitoring of unit operation.
• Serial communication with ICT-DIN-PDU6 for remote monitoring.

WARNING
Risk of serious personal injury or damage to equipment and property! Always observe the following!

• If a battery is used ensure the nominal battery voltage is correct for the model of power supply, and that the battery positive is connected to the BAT positive (+) terminal and the battery negative is connected to the NEG (-) terminal.
• Use an appropriate DC over-current protection device such as a fuse or circuit breaker in line with the battery connection.
• Do not tie the LOAD and +BAT terminals together, as this will bypass the internal LVD circuitry.
• Make Ground connection to only a single LOAD or BATT terminal if required. Do not ground both LOAD and BATT as this may bypass the internal circuitry.
• The internal LVD relay switches the BATT + terminal. Do not connect the battery + to any other terminal.
•  AC input wiring to the ICT DIN Power Supply must be protected using an outlet with a branch rated circuit breaker of 20A or lower value.

INSTALLATION

Inspect the power supply and accessories to make sure everything is complete and in good condition.
Make the following connections using wire and connectors appropriately rated for the maximum input and output current rating of the unit. The unit should be placed near the backup battery in a location that restricts access to the wiring and battery terminals, such as in an enclosed equipment cabinet. The unit is designed for the DIN Rail TS-35(EN5002) standard DIN rail in an enclosure and relies on convection cooling. Therefore, to ensure sufficient air flow there must be a minimum 4” of open space above and below the ICT DIN Power Supply.

• Install DIN Power Supply on DIN Rail TS-35(EN5002) standard DIN rail.
  

  Step 1. Push device from bottom while also pushing towards mounting rail to engage spring loaded clip| Step 2. Pivot the device towards the wall so that the top hook clips into the mounting rail as illustrated

Figure 3. Installation of ICT DIN Power supply and Distribution unit

• For a Positive-ground system, connect the power supply LOAD (+) output terminal to the “RTN” terminal which is connected to the earth ground and connect the power supply LOAD (-) output terminal to the input terminal like figure 2. Note that the ICT DIN Power Supply can be connected to an ICT DIN Power Distribution Unit as either a negative or positive-ground system.
• If the power supply is used in combination with an ICT DIN Power Distribution Unit (ICT-DIN-PDU6), the serial data cable (provided with the PDU6) can be installed to allow the Power Distribution Unit to monitor the status of the power supply. Install the power supply and Power Distribution Unit side by side, then connect the two RJ-11 COMM ports together using the data cable, as shown in Figure 2. The green “DC OK” LED will blink once every 10 seconds if the data connection is functioning properly.

Battery Backup:
✓ Choose a lead-acid battery with a nominal voltage rating (24/48V) that matches the ICT DIN Power Supply output voltage, and has an Amp-hour (Ahr) capacity rating of at least 3 times the maximum charge current setting of the power supply (e.g. Use a 45Ahr or larger rated battery (3 x 15A) with a 15A max charge setting)
✓ Connect the battery negative to the BATT (–) terminal.
✓ Connect the battery positive to an over-current protection device (fuse or breaker) and disconnect switch
✓ With the battery fuse removed or disconnect switch open, connect the fuse or switch to the BATT (+) terminal
✓ Plug the AC connector at the bottom of the front face of the unit. The earth ground is connected through AC power cable
✓ The internal LVD contactor is always connected to the battery positive though the integrated fuse (20A)

Set the charge current to be supplied to the battery by rotating the selector dial with small slotted screwdriver. Note that actual current flow to the battery may be less than the setting, and is determined by the battery state of charge and temperature.
The default Low voltage disconnect (LVD) setpoints are listed in the following chart:

WIRING
The unit has dual output circuits (Load & Battery) in a 6-pin connector. Utilize dual wiring for the LOAD connection to minimize the voltage drop due to cable length in cases where load cable is more than 15 feet from the unit. For the battery connection, utilize single wiring. Refer to the following table for the appropriate wire gauge (AWG).

Make a Ground connection (if required) to only a single +/- battery or load terminal (Load side preferred). Do not connect both the load and battery to ground as this will bypass critical internal circuitry disabling the charge control functions. The internal LVD relay is in series with the BATT + terminal.
Connect the external alarm monitoring wiring to the Form-C alarm contact output if desired, using 22-26AWG wire clamped in the removable Alarm/Temp plug. (See
Alarm Output Contacts table below)

Connect the optional remote battery temperature sensor:

Connect the temperature sensor (ICT-TMP) to the TEMP input on the removable connector. Using the temperature sensor will enable the unit to compensate the charge Float voltage according to the battery case temperature, to help fully charge cold batteries and ensure warm batteries are not over charged. Connect each of the two wires on the remote temperature probe to the two TEMP inputs on the connector (polarity does not matter). Affix the probe body to a side midpoint on one of the battery cases using the adhesive backed plastic clip included with the sensor.

OPERATION

Plug the AC input connector into the unit and check that the green “DC OK” LED on the front of the unit is lit. Verify the supply output voltage using a handheld digital voltmeter. If a battery is connected, install the external fuse, and close the disconnect switch. If the external back-up battery is connected, disconnect AC power and use a handheld digital voltmeter to verify that the battery voltage is provided to the output load terminal. Reconnect AC power and verify the output supply voltage rises to the normal output rating as the battery charges.
The unit can now be left operating normally. As long as the external back-up battery voltage is greater than the low voltage disconnect (LVD) level, the battery will be connected directly to the supply output and will instantly power the load in case of an AC power failure. When AC power is lost, the battery will gradually be discharged by the load. When the battery voltage drops below the LVD disconnect level the internal relay will open preventing the battery from being excessively discharged.

When AC power returns, the unit will close the LVD relay and charge the battery to bring the voltage back up to the float voltage level. Battery charge current is adjusted by rotating the “CHARGE CURRENT” selector dial with slotted screwdriver. The adjustable level of battery charge current is 25%/50%/75%/100% of available output current, and the factory default is 25%. Batteries will be charged to the supply output voltage level with current limited to the maximum supply output rating. To increase the battery charging current, rotate the selector dial clockwise. Combined with the ICT DIN Power Distribution Unit, remote monitoring is available through the Ethernet controller and user interface showing in figure 4.

CAUTION
Risk of damage to equipment!

• Ensure battery current supplied through the internal LVD contactor cannot exceed the current rating of the unit
• Do not use the internal LVD contactor for parallel applications where load current can exceed the maximum rating of a single unit
