Convection cooled power supply withstands severe environments

Power Supply / Management

ABSOPULSE HVI 3KP-V9 rugged, convection cooled power supply drives low voltage 24V, 48V, or 125Vdc equipment in severe environments where fans or forced air are not practicable, and high instantaneous power is required. Unit 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. Typical conversion efficiency is 85% at full load depending on input/output configuration. Unit 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.15SEP286_ROB
