Description
The Chinfa DRA18-24 is a compact DIN rail power supply designed for industrial automation, machinery and control-panel applications. This spring-terminal version provides a regulated 24VDC output at up to 0.75A, delivering 18W of continuous output power.
A universal 90 to 264VAC input range, internal input filtering and a slim 22.5mm-wide enclosure make the DRA18-24 well suited to space-constrained industrial installations.
The unit mounts directly onto a standard 35mm DIN rail and includes integrated short-circuit protection for reliable operation in control cabinets.
Chinfa DRA18-24 24V 0.75A DIN Rail Power Supply
A slim 18W industrial AC-DC power supply with universal input, regulated 24VDC output and spring-terminal connections.
The DRA18-24 converts a single-phase AC input into a stable 24VDC supply for low-power industrial control and automation equipment. Its compact 22.5mm width makes it particularly useful where DIN rail space is limited.
Typical Applications
- Industrial automation and machinery
- PLC and remote I/O systems
- Sensors, relays and instrumentation
- Building automation
- Security and access-control systems
- Compact 24VDC control panels
Universal AC Input
The DRA18-24 accepts a wide 90 to 264VAC input, allowing operation from common mains systems without manual voltage selection.
18W Regulated Output
The unit delivers a nominal 24VDC output at up to 0.75A, providing 18W of continuous output power.
Slim DIN Rail Design
At only 22.5mm wide, the DRA18-24 helps conserve valuable panel space while still providing a fully enclosed industrial power solution.
Spring-Terminal Connections
This version uses spring-terminal connections for quick, secure and maintenance-friendly field wiring. The absence of the A suffix distinguishes it from the fixed screw-terminal DRA18-24A model.
Integrated Protection
Built-in short-circuit protection helps protect the power supply and connected equipment during abnormal operating conditions.
