Product Usage Instructions
To use the 24V/40A DIN Rail Type Uninterruptible DC-UPS Module (DUPS40), follow these instructions:
- Connect the DC UPS input to a power supply with a normal input voltage of 24Vdc.
- Ensure that the input voltage range is within 24 ~ 29Vdc.
- Connect the DC UPS output to the load that requires uninterrupted power.
- Connect the battery to the module. The battery should have a normal voltage of 24Vdc (can be achieved by connecting 2 x 12Vdc batteries in series or using a single 24Vdc battery).
- Make sure the battery type is a lead-acid battery with capacities ranging from 4AH to 135AH.
- For protection against short circuits, it is recommended to use an external fuse when batteries are connected.
- Ensure that the working temperature is within the range of -30~ +70°C. Refer to the provided derating curve for temperature-dependent adjustments.
- Avoid operating the module in extreme humidity conditions (5 ~ 95% RH non-condensing).
- The module can be stored in temperatures ranging from -40 ~ +85°C.
- To test the battery, check the LED display status. A green LED indicates a successful battery test, a red LED indicates battery over-discharge warning or battery broken, and a yellow LED indicates battery discharging.

Description
The DUPS40 is a 40A DIN rail type DC-UPS module, and it is paired with a power supply and an external battery to achieve the backup function. When the AC mains fails or is interrupted, the load will be immediately connected to the battery pack to avoid interruption and to ensure the continuous operation of the entire system (the operating time depends on the capacity of the battery pack). The main features of DUPS40 include: fast installation, suitability for 24V battery packs and various capacities of 4AH~135AH, 2A battery charging current, low voltage disconnect for battery protection and more. The product is suitable for use in data centers, security systems, emergency lighting, wireless communication UPS, central monitoring systems, etc.

NOTE
|
- All parameters NOT specially mentioned are measured at normal input(24V), rated load and 25 C of ambient temperature.
- Every 30 seconds, unit will test the battery.If the testing result is faulty, unit will turn on “Battery Fail” relay contact and “Red LED” indicator.
- Derating may be needed over high ambient temperature. Please check the derating curve for more details.
- The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).
- The unit is considered a component which will be installed into a final equipment. All the MC tests are been executed by mounting the unit on a 360*720mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets MC directives. For guidance on how to perform these MC tests,please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)
