Description
The Chinfa DRA18-12 is a compact DIN rail power supply designed for industrial automation, machinery and control-panel applications. This spring-clamp terminal version delivers a regulated 12VDC output at up to 1.5A, providing 18W of continuous output power.
A universal 90 to 264VAC input range, internal input filtering and compact 22.5mm-wide housing make the DRA18-12 well suited to space-constrained industrial installations.
The plastic enclosure mounts directly onto a standard 35mm DIN rail and includes integrated protection against short circuit and overcurrent conditions.
Chinfa DRA18-12 12V 1.5A DIN Rail Power Supply
A compact 18W industrial AC-DC power supply with universal input, regulated 12VDC output and spring-clamp terminals.
The DRA18-12 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, instrumentation, communications equipment and other low-power 12VDC loads.
Typical Applications
The Chinfa DRA18-12 is suitable for applications including:
- Industrial automation and machinery
- PLC and remote I/O systems
- Sensors, relays and control equipment
- Process-control instrumentation
- Industrial communications equipment
- Security and access-control systems
- Compact 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 120 to 375VDC source, supporting installation across common industrial supply systems without manual voltage selection.
18W Regulated Output
The DRA18-12 delivers a nominal 12VDC output at up to 1.5A, providing 18W of continuous power for industrial loads.
Compact 22.5mm Housing
With a width of only 22.5mm, the DRA18-12 is ideal for control cabinets where DIN rail space is limited.
Spring-Clamp Terminals
This version uses spring-clamp terminals for quick, secure and maintenance-friendly field wiring. The model is supplied without the A suffix, distinguishing it from the screw-terminal DRA18-12A version.
Internal Input Filter
An integrated input filter helps reduce conducted electrical noise and supports reliable operation in industrial environments.
Integrated Protection
Short-circuit and overcurrent protection help safeguard the power supply and connected equipment during abnormal operating conditions.
