Description
The Chinfa DRA240-24A is a robust DIN rail power supply designed for industrial automation, machinery and control-panel applications. This 24V A-version uses fixed screw terminals and delivers up to 10A, providing 240W of regulated DC output power.
A wide 90 to 264VAC input range, high efficiency and integrated power factor correction make the DRA240-24A suitable for industrial installations worldwide. The supply also includes front-panel output-voltage adjustment and switch-selectable parallel operation.
The metal enclosure mounts directly onto a standard 35mm DIN rail and includes protection against short circuit, overload and overvoltage conditions.
Chinfa DRA240-24A 24V 10A DIN Rail Power Supply
A 240W industrial AC-DC power supply with universal input, adjustable 24VDC output, parallel-operation capability and fixed screw terminals.
The DRA240-24A converts a single-phase AC or compatible high-voltage DC input into a stable 24VDC supply for industrial control and automation equipment. Its 10A output capacity makes it suitable for PLCs, HMIs, remote I/O, actuators, communications equipment and other 24VDC loads.
Typical Applications
The Chinfa DRA240-24A is suitable for applications including:
- Industrial automation and machinery
- PLC, HMI and remote I/O systems
- Motors, actuators, solenoids and contactors
- Process-control and factory-automation equipment
- Packaging and material-handling systems
- Industrial communications and monitoring equipment
- 24VDC control panels and instrumentation
Wide AC and DC Input
The DRA240-24A accepts a wide 90 to 264VAC input and can also operate from a 120 to 375VDC source. This allows use across common industrial mains systems without manual voltage selection.
240W Regulated Output
The power supply provides a nominal 24VDC output at up to 10A, delivering 240W of continuous output power for industrial control and automation loads.
Adjustable Output Voltage
A front-panel adjustment control allows the output voltage to be fine-tuned to compensate for cable voltage drop or to suit the requirements of connected equipment.
Power Factor Correction
Integrated power factor correction improves input-current quality and supports efficient operation across the unit’s wide input range.
Parallel Operation
A switch-selectable parallel function allows compatible DRA240 power supplies to be connected in parallel where increased output capacity or system redundancy is required.
Fixed Screw-Terminal Version
The A suffix identifies the fixed screw-terminal version, providing secure and straightforward 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.
