Description
The Chinfa DRA100-24A is a compact 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 4.2A, providing 100.8W of regulated DC output power.
A universal 90 to 264VAC input range, internal input filtering and high efficiency make the DRA100-24A suitable for industrial installations operating from common mains supplies worldwide.
The compact plastic enclosure mounts directly onto a standard 35mm DIN rail and includes protection against short circuit, overload and overvoltage conditions.
Chinfa DRA100-24A 24V 4.2A DIN Rail Power Supply
A compact 100.8W industrial AC-DC power supply with universal input, regulated 24VDC output and fixed screw terminals.
The DRA100-24A converts a single-phase AC or compatible high-voltage DC input into a stable 24VDC supply for industrial control and automation equipment. Its 4.2A output capacity makes it suitable for PLCs, HMIs, sensors, relays, instrumentation and other regulated 24VDC loads.
Typical Applications
The Chinfa DRA100-24A 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
- 24VDC 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.
100.8W Regulated Output
The DRA100-24A delivers a nominal 24VDC output at up to 4.2A, providing 100.8W of continuous power for industrial loads.
Adjustable Output Voltage
A front-panel adjustment control allows the output voltage to be fine-tuned from approximately 22.5 to 28.5VDC. This can be used to compensate for cable losses or match the requirements of connected equipment.
Internal Input Filter
An integrated input filter helps reduce conducted electrical noise and supports reliable operation in industrial control environments.
Fixed Screw-Terminal Version
The A suffix identifies the fixed screw-terminal version, 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.
