TDI is introducing a complete series of environmentally sealed power modules (ESPM). The first modules to be released are the efficient and ruggedized 1000 and 2700W units. These modules are designed to withstand and operate reliably in harsh environments and critical applications. The ESPM series is also electrically hardened to survive severe AC input transients.

Performance features include high efficiency operation, wide AC input ranges, sinusoidal power factor correction, remote control and monitoring, N+1 redundant parallel operation, EMI conformance and closely regulated and conditioned output. The internal electronics are encased within the sealed aluminum chassis that provides environmental protection from the elements. The 1000 W module is encapsulated with a thermally conductive, flexible silicon elastomer whereas the 2700 W modules are filled with thermally conductive oil. Both technologies efficiently conduct heat from the components to the finned chassis and in turn to the outside cooling air.

The ESPM series is ideally suited for Telecommunications Base Stations, Towers and Shelters, Off-Shore Platforms, Chemical Plants, Industrial Processing and Control, Mobile Trucks and Vehicles, and other unsavory applications. ESPMs are NEMA rated for Watertight, Submersible, Dusttight, Corrosion Resistant, Steel Resistant and Hazardous Locations. They have an extended operational temperature range of – 30’C to +55’C after a 30 minute warm up, which can be extended to +70 ‘C with power derating. Their audible noise is undetectable. Connection options include tethered cables, terminal blocks or weather tight connectors.
