3kW, Convection Cooled, Ultra-rugged Industrial Power Supply for Severe Environments


HVI-3KP-V9 convection cooled high input voltage IP54-3kW

3kW, 3-phase input convection cooled power supply in IP54-rated Enclosure

The HVI 3KP-V9 is a rugged, convection cooled power supply designed for driving low voltage 24V, 48V, or 125Vdc equipment in severe environments where fans or forced air are not practicable, and high instantaneous power is required. Typical applications include electro-mechanical lifting and positioning equipment, winches, pumps, and a broad range of other industrial machinery and equipment.

The power supply accepts a 400Vac, 3-phase input and delivers between 2,500 and 3,500W, depending on application requirements. 125Vdc or higher DC-inputs are also available. Power factor corrected (PFC) input can be provided on request. Typical conversion efficiency is 85% at full load depending on input/output configuration.

It is built with rugged internal power modules, each separated by a built-in redundancy diode. The internal redundancy diodes allow for a number of units to be connected in parallel to achieve higher output power. Regulation is better than 2% from no load to full load, including redundancy diode.

Each internal power module is encapsulated with a thermally conductive MIL-grade silicon rubber potting compound with UL94V-0 flammability rating. This makes it impervious to moisture and other contaminants, and ensures immunity to shock and vibration. The system is packaged in an IP54 enclosure which provides protection from dust, metallic dust and water spray.

Cooling is by convection via heat-sink fins on two sides of the unit. The potting of the internal modules ensures effective heat transfer to the fins. The HVI 3KP-V9 operates over a 0°C to +50°C temperature range for full specification with no requirement for temperature derating. Requirements for wider temperature ranges can be accommodated.

The input and output are filtered for low noise. The input meets EN55022 Class A with margins. The power supply is designed for compliance with EN/UL60950-1 and equivalent safety standards. Full electronic protection, low component count, large design headroom and the use of components with established reliability contribute to an MTBF of a minimum of 90,000 hours at 45°C.

The design is also available in customized versions with higher and lower output power, and different sizes.
