MEAN WELL DR-UPS40 40A DC UPS Module

Product Usage Instructions

Installation

Ensure the DIN Rail UPS system is powered off.
Mount the DR-UPS40 module on DIN Rail TS35/7.5 or TS35/15 securely.
Connect the DC input within the specified voltage range.
Connect the external battery according to the recommended specifications.

Operation

Power on the DIN Rail UPS system.
Monitor the LED indicators for DC BUS OK, Battery Fail, and Battery Discharge status.
Utilize the relay contact signals for additional monitoring if required.

FAQ

Q: What is the purpose of the built-in battery test function?
A: The battery test function helps to ensure the proper functioning of the battery by sending out test signals periodically and indicating any issues with the battery.
Q: Can the DR-UPS40 module be used in parallel connection?
A : Yes, the module supports parallel connection to the DC BUS for enhanced power supply capabilities.

DIMENSION| 55.5125.2100mm (WHD)
PACKING| 0.55Kg; 20pcs/12Kg/1.49CUFT
NOTE| 1. All parameters NOT specially mentioned are measured at rated load and 25℃ of ambient temperature.

2. Battery failure will only function at UPS mode with the battery connected. Every 25 seconds, the unit will send out a test signal through the “Battery Fail” relay contact and LED indicator once the battery fails.

3. The power supply is considered a component that will be installed into the final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re- confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”

4. Battery charging will be in progress when DC input > battery voltage.

5. DR-UPS40 will be in operation when DC input is applied at the beginning.

6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitudes higher than 2000m(6500ft).
