Inrush Current Limiter Protects Avionics and Military Power Systems
Wed, 09/21/2011 - 11:38am
VPT Inc., a HEICO company announced a new power protection module, the DVCL Inrush Current Limiter. The module controls potentially damaging inrush current drawn by DC-DC converters, EMI filters, and discrete capacitors during startup. With a power capacity of 200 W, users can protect multiple downstream VPT DC-DC converters using a single, lightweight DVCL module. The DVCL Inrush Current Limiter functions by limiting the rate of rise of its output voltage. It will also control the inrush current of discrete input capacitors. Feautres include a profile of 1.075 in2), light weight, 99 percent efficiency, and a hermetic package to ensure full performance over -55°C to +125°C military temperature range. Input voltage range is 11 V to 50 V per MIL-STD-704; high input transient voltage is 80 V for 1 second, and it is available compliant to MIL-PRF-38534, Class H.
