Abb 1svr427031r0000 Din Rail Power Supply 30W 24VDC

Product Description

The ABB 1svr427031r0000 is a single-phase, switch mode DIN rail power supply from the CP-E range, designed for industrial control panel applications. It accepts a wide-range input of 85 to 264 volts AC or 90 to 375 volts DC, with a rated input voltage of 100 to 240 volts AC at 47 to 63 Hz. The rated output is 24 volts DC at 1.25 amps, delivering 30 watts of continuous output power. Output voltage is field-adjustable from 24 to 28 volts DC. A U/I output characteristic supports parallel operation for redundancy configurations, and a transistor-type signaling output indicates when output voltage is within spec. Licensed electricians and control panel integrators handle installation.

This power supply is suited for residential and commercial control panel builds, machine automation enclosures, and industrial field cabinets where a compact, DIN rail-mounted 24 VDC supply is required. Its wide-input voltage range makes it well-suited for global and multi-voltage installations. The unit supports parallel operation, allowing redundancy setups when paired with an appropriate ABB redundancy unit accessory. IP20 protection on both the housing and terminals makes it appropriate for use inside enclosed control panels where pollution degree 2 conditions apply.

Compatibility

Designed as a DIN rail-mounted switch mode power supply for industrial and commercial control panel applications requiring a 24 VDC, 1.25-amp regulated output. A compatible ABB redundancy unit is available as a separately ordered accessory.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and the panel builder's documentation. De-energize the control panel and verify absence of voltage before wiring input or output terminals. Input and output conductors from 24 to 14 AWG (rigid) are accepted; strip length is 6 mm and terminal tightening torque is 5 in-lb for UL/CSA installations. Maintain a minimum mounting clearance of 25 mm on all sides from conductive surfaces and adjacent devices of the same type.
