Description
The Chinfa DRA18-12A is a compact DIN rail power supply designed for industrial automation, instrumentation and control-panel applications. This 12V A-version uses fixed screw terminals and delivers up to 1.5A, providing 18W of regulated DC output power.
A universal 90 to 264VAC input range, internal input filtering and efficient natural-convection operation make the DRA18-12A suitable for low-power industrial installations operating from common mains supplies worldwide.
The slim 22.5mm-wide plastic enclosure mounts directly onto a standard 35mm DIN rail and includes integrated protection against overcurrent, overvoltage and short-circuit conditions.
Chinfa DRA18-12A 12V 1.5A DIN Rail Power Supply
A slim 18W industrial AC-DC power supply with universal input, regulated 12VDC output and fixed screw terminals.
The DRA18-12A converts a single-phase AC or compatible high-voltage DC input into a stable 12VDC supply for industrial control and automation equipment. Its 1.5A output capacity makes it suitable for sensors, relays, compact controllers, instrumentation and other low-power 12VDC loads.
Typical Applications
The Chinfa DRA18-12A is suitable for applications including:
- Industrial automation and machinery
- Sensors, relays and control equipment
- Compact PLC and remote I/O systems
- Instrumentation and measurement equipment
- Security and access-control systems
- Industrial communications equipment
- 12VDC control panels
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 allows use across common industrial mains systems without manual voltage selection.
18W Regulated Output
The DRA18-12A delivers a nominal 12VDC output at up to 1.5A, providing 18W of continuous output power for low-power industrial loads.
Compact 22.5mm Width
The narrow enclosure helps conserve valuable DIN rail space, making the unit well suited to compact control panels and distributed automation systems.
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
Overcurrent, overvoltage and short-circuit protection help safeguard the power supply and connected equipment during abnormal operating conditions.
