Product Usage Instructions

To use the 24V/20A DIN Rail Type Uninterruptible DC-UPS Module (DUPS20), follow these instructions:

1. Make sure the input voltage for the DC UPS is within the range of 24V to 29Vdc.
2. Connect the DC UPS module to the appropriate industrial control system or semiconductor fabrication equipment using parallel connection to the DC BUS.
3. Choose a suitable lead-acid battery with capacities ranging from 4AH to 135AH.
4. Connect the battery to the DC UPS module, ensuring correct polarity.
5. If batteries are not connected, it is recommended to use an external fuse for short circuit protection.
6. The DC UPS module supports a discharge current range of 0 to 20A. Ensure that the load does not exceed this range.
7. To charge the battery, connect a power supply with a charging current of 2A to the DC UPS module.
8. Monitor the LED indicator for signal status, which will indicate the battery’s OK status or any warnings related to battery over-discharge or breakage.
9. The DC UPS module provides complete diagnostic and monitoring for DC BUS OK, battery discharge, and battery fail. Refer to the user manual for details on interpreting these diagnostics.
10. The module is cooled by free air convection, so ensure proper ventilation for optimal performance.

Description

The DUPS20 is a 20A 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 DUPS20 include: fast installation, small size (only 40mm wide)suitability for 24 V 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

| 1. All parameters NOT specially mentioned are measured at normal input(24V) , rated load and 25℃ of ambient temperature.

2. 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.

3. Derating may be needed over high ambient temperature. Please check the derating curve for more details.

4. The ambient temperature derating of 3.5℃I1000m with fanless models and of 5℃I1000m with fan models for operating altitude higher than 2000m(6500ft).

5. The unit is considered a component which will be installed into a final equipment. All the EMC 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 EMC directives. For guidance on how to perform these EMC tests,please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)
