Low profile AC-DC power supply series delivers high performance at low cost

Stadium Stontronics has introduced a low-cost SRS series of medium- to high-power single-output enclosed type AC-DC power supplies. Designed with a very high price to performance ratio these power supplies are intended for use in industrial automation, control, instrumentation and household appliance applications.

All of the series variants have a low profile of 30mm that enable multiple units to be installed in the same platform for ease of use, and to allow them to fit easily within a standard 1U metal enclosure.

Model versions are available at 35W, 50W, 75W, 100W, 150W, 200W and 350W with a range of output voltages from 5VDC to 48VDC. Each model has a single terminal block with a safety barrier and is enclosed in a mesh safety case that enables convection cooling. This is supported by high efficiency up to 91%, which generates less waste heat and keeps down internal component temperatures.

The SRS series operates at temperatures from – 30°C to 70°C across the range, with each product providing full power down to an AC Input of 100VAC with de-rated operation down to 85VAC for international markets with a wide range of input conditions. The EMC emissions meet EN55022 Level B.

All units have a LED power indicator and a range of protection features including over-current shutdown with auto-recovery and over voltage protection. Below 200W the unit is convection cooled with the 350W unit having an integral fan. All units have a 100% burn-in before leaving the factory and are supplied with a three-year warranty.
