Description
The Chinfa DRE240-12A is a compact industrial DIN rail power supply with a regulated 12VDC output and screw-terminal connections. It delivers up to 16A and 192W of continuous output power, making it suitable for automation, machinery and control-panel applications.
A universal 88 to 264VAC input, built-in active power factor correction and high operating efficiency allow the DRE240-12A to be used across a wide range of industrial installations. The supply also provides 150% peak-load capability for equipment with short-duration start-up or surge-current demands.
The robust metal enclosure mounts directly onto a standard 35mm DIN rail. Integrated protection against short circuit, overload, overvoltage and overtemperature helps protect both the power supply and connected equipment.
Chinfa DRE240-12A 12V 16A DIN Rail Power Supply
A high-efficiency 12VDC industrial power supply with universal AC input, active PFC and screw-terminal connections.
The DRE240-12A converts a universal single-phase AC supply into a stable 12VDC output for industrial control, automation and communications equipment. Although part of the DRE240 series, the 12V model is rated at 192W continuous output, supplying up to 16A.
Typical Applications
The Chinfa DRE240-12A is suitable for applications including:
- Industrial automation and machinery
- PLC, HMI and remote I/O systems
- 12VDC control panels and distribution systems
- Sensors, relays, solenoids and actuators
- Industrial communications and networking equipment
- Security, access-control and monitoring systems
- Equipment with short-duration peak-current requirements
Universal AC and DC Input
The power supply accepts 88 to 264VAC or 120 to 375VDC, providing flexibility for use with common industrial and commercial supply systems.
12VDC, 16A Continuous Output
The DRE240-12A delivers a regulated 12VDC output at up to 16A, providing 192W of continuous power for high-current 12V industrial loads.
150% Peak-Load Capability
Peak-load capability of up to 150% supports equipment that requires additional current for short periods, such as motors, capacitive loads and electromechanical devices.
Active Power Factor Correction
Built-in active PFC improves input-current characteristics and helps the supply operate efficiently across its wide input-voltage range.
Parallel Operation
A switch-selectable parallel function allows compatible DRE240 units to be connected where increased output capacity or system redundancy is required.
Screw-Terminal Connections
The A-version uses fixed screw terminals for secure field wiring within industrial control cabinets.
Compact Metal Enclosure
The unit is housed in a robust metal case measuring 124.5 x 64 x 123.6mm and mounts onto a standard 35mm DIN rail. Natural convection cooling eliminates the need for a fan.
