Performance Parameters​

Load Regulation​

Output voltage remains within the module’s declared regulation band from no-load to rated load.

Efficiency​

Operating efficiency depends on input voltage, output load and ambient temperature stated in the Reliance data sheet.

Reliability​

Designed for continuous cabinet operation with filtered ventilation and correct derating.

Structural Features​

Housing​

Sheet-steel or molded industrial enclosure with vent openings according to variant.

Terminal Section​

Screw or spring terminals for AC input, DC output and protective earth.

Indicator Section​

LED or mechanical indicators for input power and output status where fitted.

Material Composition​

Enclosure​

Coated steel or flame-retardant thermoplastic according to the specific 45C922 package.

PCB​

Industrial-grade printed circuit board with conformal coating where required.

Power Components​

Transformers, rectifiers, capacitors and regulation semiconductors selected for continuous-duty industrial loads.

Terminals​

Tin-plated copper alloy contacts with strain-relieved cable entries.

Working Principle​

The module receives 115/230 VAC input, performs voltage step-down or conversion, rectifies and filters the supply, regulates the output to the required DC level, and monitors load current. Protection circuits disconnect or limit output during overload, short circuit or overtemperature conditions, then restore normal operation according to the reset and auto-recovery configuration.

Installation Requirements​

De-energize the cabinet before installation. Confirm the input voltage selector matches the site supply. Mount the module in a dry, ventilated enclosure with clearance for heat dissipation. Separate AC power wiring from low-voltage signal wiring. Connect protective earth before applying load. Verify output polarity and voltage with a calibrated meter before connecting automation equipment.

Usage Precautions​

Do not apply voltage outside the 115/230 VAC nameplate range. Do not operate in open, wet or dusty environments below IP20 requirements. Do not exceed the rated output current. Replace the module if overheating, burning odor, intermittent output or insulation damage occurs. Use only Reliance-approved replacement parts and perform insulation checks after any electrical fault.
