The bucks are phased in 90A steps to reduce noise and input ripple, have forward and reverse current limiting, softstart to limit inrush current during startup, and shortcircuit
iWatt's primary-side-control technology eliminates the opto-coupler, and coupled with low inrush current and low ripple current by design, lengthens the life of the LED driver assembly.
They feature 3-phase sequence and motor rotation to properly test the connection of a motor to a 3-phase system, inrush current to verify a motor is receiving the required current to support proper motor start, and HVAC capabilities such as temperature measurement and DC Microamps output for flame sensor testing in gas appliances.
