Ultra-high power density open frame power supplies

Paul Boughton
Gresham Power Electronics’ HD365 series of high-density ac to dc switch-mode power supplies that deliver up to 365 watts, approximately twice the power currently available in the industry standard 76.2 x 127mm (3 x 5”) footprint. 

With a height of only 33mm (1.30 inches) these supplies are suit low profile, 1U High applications.

The HD365 series utilises the latest technologies and advanced switching topologies to deliver operational efficiencies up to 90 per cent with a power density exceeding 18W/in3, setting the standard for low and medium range power products.

These single-output power supplies offer standard output voltage set points of 5 / 12 / 24 /48 Vdc with standard features of: Universal ac Input (85 to 264Vac), Active Power Factor Correction (EN61000-3-2 Class D Compliant), Protection against over-temperature, over-current and over-voltage conditions. Safety Approvals for: Information Technology Equipment (ITE), (UL/cUL60950-1 / EN60950-1), Medical (UL/cUL 60601-1/EN60601-1), the CE Mark (LVD), and conform to FCC / EN55022 Level B Emission Standards. 

The HD365 Series offers reliable performance, high MTBF and is ROHS compliant. This series is ideal for a wide range of applications which include: Front-Ends for Distributed Power Architecture (DPA or IBA) in Telecom, Industrial, Military COTS, Medical and Scientific Instrumentation.
