DRC-40A Mean Well — Switching Power Supply

Introducing the DRC-40A Mean Well switching power supply with UPS buffer function, from the U-tex brand. This compact device is designed to provide uninterrupted power to low-voltage equipment and is suitable for installation in industrial and commercial control systems. The output description states: 40.02 W, 13.8 V/2.9 A and 13.8 V/1 A; detailed channel characteristics are provided below.

• Power Supply Type: Switching with buffer function (UPS function), ensuring automatic switchover to backup power upon mains failure.
• Mounting: On DIN rail TS-35/7.5 or TS-35/15 — convenient for installation in automation cabinets and electrical panels.
• Input Voltage: Universal range 90–264 V AC or 127–370 V DC, making the device flexible for various power sources.
• Output Power: Nominal power is 40.02 W.
• Output Voltage/Current (Summary): The brief description indicates 13.8 V/2.9 A and 13.8 V/1 A.
• Output Channels (Detailed):
  • Channel 1 (Main): 13.8 V DC, 1.9 A.
  • Channel 2 (Charging/Buffer): 13.8 V DC, 1 A.
• Efficiency: Up to 86% — high energy efficiency reduces heat loss and increases system reliability.
• Protection: Includes short-circuit, overload, overvoltage protection, as well as battery protection against deep discharge and reverse polarity (via fuse).
• Alarm: Output alarm signals are present to indicate mains failure (AC OK) and low battery (Battery Low) via an open-collector TTL output; relay output is optionally available.
• Cooling: Natural air convection cooling, ensuring silent operation without fans.
• Dimensions: 40 x 90 x 100 mm — compact housing to save space in the equipment cabinet.
• Operating Temperature: From -30°C to +70°C, allowing operation in harsh climatic conditions.

The DRC-40A Mean Well from U-tex combines reliability, compactness, and a full set of protections and alarms necessary for industrial applications and uninterruptible power supply systems. If you need a power supply with UPS mode for battery backup and continuous operation of low-voltage devices in automation cabinets, this device will be an excellent choice. The text retains all technical parameters: nominal power 40.02 W, mentioned output values 13.8 V/2.9 A and 13.8 V/1 A, as well as a detailed breakdown by channels 13.8 V DC at 1.9 A and 1 A respectively.

Other technical details, mounting features, and protection options make the DRC-40A suitable for integration into access control systems, security systems, telecommunications equipment, and other solutions where energy independence and stable power are required.
