Tired of blowing main fuses? Well, you're not the first nor the last. The truth is today's circuit breakers are just not fast enough and fuses can get very expensive. Try this Inductotherm ITC (but not limited to) Precision one piece 3 phase bridge control board. The terminal block is clearly labeled for an easy DIY installation. The input power requirements will need to be a (switched type) 24vdc power supply with a minimum of 1.3 amps capability. Equipped with 3 phases of precision current measurement with the advantage of using low cost 2va Current transformers. The current transformer requirements will need to be a minimum of 2va with a 5-amp secondary and will connect directly to inputs CT1, CT2, CT3 for a direct current measurement. The current transformers are (NOT INCLUDED) in this listing due to variation requirements specific to power supply. There are 2 independent dry interlock contacts, (1) N/O (1) N/C. The reset requirements are to be a N/O contact momentary push button. Equipped with 6 outputs with phoenix connectors clearly labeled with "G" gate and "K" cathode which can work with any SCR or thyristor module. Connection drawing, and instructions will be included for installation. THIS WILL WORK ON ANY 3-PHASE BRIDGE RECTIFIER IN ANY BRAND POWER SUPPLY.  If you have any questions just ask.
