Power Supply for DIN-Rail Applications

The NShi DRS-240-12 is a 240 W DIN-rail power supply that delivers 12 VDC at 20 A. It accepts a wide AC input range of 90 VAC to 305 VAC at 47 Hz to 63 Hz. An integrated battery charge circuit provides backup capability for critical loads. The desktop chassis suits industrial and automation cabinets.

Ideal for Industrial Control Panels

This unit fits panels that require a compact 12 V source with battery-backed redundancy. Installers who need a different output voltage or a higher power rating should select another model. Builders without DIN-rail mounting provisions cannot use this form factor.

Single-Rail 12 VDC at 240 W

The supply provides a single 12 V rail rated for 20 A continuous current. The 240 W limit determines how many devices can be powered simultaneously. Verify that the total load stays within this rating before installation.

Questions about this item

What input voltage range must my facility supply for this 240 W unit to operate?

The power supply accepts 90 VAC to 305 VAC at 47 Hz to 63 Hz, so any standard single-phase service within that window will work.

Can I keep my existing 12 VDC battery bank connected to the built-in charge circuit?

Yes, the supply includes a battery charge circuit designed for 12 VDC banks, allowing continuous float charging alongside the 20 A load output.

How do I verify the 12 VDC output is delivering the rated 20 A after installation?

Measure the output terminals under load with a calibrated multimeter; a stable reading near 12 VDC while drawing up to 20 A confirms correct operation.
