Description
The Chinfa DRAN120-12A is a compact DIN rail power supply designed for industrial automation, machinery and control-panel applications. This 12V screw-terminal version delivers up to 10A, providing 120W of regulated DC output power.
A universal single-phase AC input, active power factor correction and adjustable output make the DRAN120-12A suitable for industrial systems operating from common mains supplies. The unit also provides switch-selectable parallel operation for applications requiring increased capacity or redundancy.
The robust metal enclosure mounts directly onto a standard 35mm DIN rail and includes protection against short circuit, overload and overvoltage conditions.
Chinfa DRAN120-12A 12V 10A DIN Rail Power Supply
A compact 120W industrial power supply with universal input, active PFC, adjustable 12VDC output and fixed screw terminals.
The DRAN120-12A converts a single-phase AC or compatible DC input into a stable 12VDC supply for industrial control and automation equipment. Its 10A output capacity makes it suitable for powering control systems, instrumentation, communications equipment and other regulated 12VDC loads.
Typical Applications
The Chinfa DRAN120-12A is suitable for applications including:
- Industrial automation and machinery
- PLC, HMI and remote I/O systems
- Sensors, relays and control equipment
- Process-control and factory-automation systems
- Industrial communications equipment
- Security, monitoring and access-control systems
- 12VDC control panels and instrumentation
Universal AC and DC Input
The power supply accepts a wide 90 to 264VAC input and can also operate from a compatible high-voltage DC source. This supports use across common industrial mains systems without manual voltage selection.
120W Regulated Output
The DRAN120-12A delivers a nominal 12VDC output at up to 10A, providing 120W of continuous power for industrial loads.
Adjustable Output Voltage
The output can be adjusted from approximately 11.4 to 14.5VDC, allowing compensation for cable losses or matching to the requirements of connected equipment.
Active Power Factor Correction
Built-in active PFC improves input-current quality and helps the unit operate efficiently across its wide input range.
Parallel Operation
A switch-selectable parallel function allows compatible DRAN120 power supplies to be connected in parallel where additional output capacity or redundancy is required.
Screw-Terminal Version
The DRAN120-12A is the fixed screw-terminal version of the series, providing secure field wiring for permanent installation inside industrial control cabinets.
Integrated Protection
Short-circuit, overload and overvoltage protection help safeguard the power supply and connected equipment during abnormal operating conditions.
