Used by inverter and power supply manufacturers, SurLok Plus is optimised for battery pack connections from 50 A to 400 A using a touch-safe interface. This robust, low profile, right angle design, RADSOK connector is quick mating and significantly increases amperage while reducing insertion force, rises in temperature and voltage drop.
