MEAN WELL DRC & DRS DIN Rail Security Power Supplies
Product Features
Both the DRC and DRS series offer integrated UPS functionality designed for DIN Rail (TS-35/7.5 or 15) installation. They automatically switch to battery power during AC outages, ensuring zero downtime for critical systems.
- DRC Series (Standard Level): A compact, cost-effective solution providing basic power supply and battery charging functions. Includes essential alarm signals (AC OK and Battery Low) via relay contacts.
- DRS Series (Intelligent All-in-One): An advanced, multi-functional unit integrating a power supply, DC-UPS, battery charger, and system monitor into one compact module. Supports broad battery chemistries (Lead-Acid and Lithium-ion).
- Battery Protection: Both series feature critical protections including Battery Low Disconnect (preventing deep discharge) and Battery Reverse Polarity protection.
- Load Prioritization (DRS): The DRS series automatically adjusts the battery charging current based on the primary load's power draw, ensuring the main equipment is always adequately powered.

| Feature | Description |
|---|---|
| Smart Charging Curves | Features 2-stage or 3-stage programmable charging curves. Curves can be selected via front-panel DIP switches or custom-programmed using the MEAN WELL SBP-001 smart programmer. |
| Digital Communication | Optional MODBus or CANBus protocols allow direct integration into PLC or building management networks for real-time data logging and remote control. |
| Form-C Relay Contacts | Provides comprehensive hardwired status signals including: AC Fail, DC OK, Battery Low, and Charger Fail. |
Ordering Logic for DRS: Add a suffix for communication protocols. Blank = Standard model without communication; CAN = CANBus protocol; MOD = MODBus protocol. (e.g., DRS-240-24CAN).
