Programma's B10E power supply unit
May 2010
Electrical Power & Protection
The best way to ascertain whether or not solenoids and protective mechanisms are sluggish or set improperly is to perform a test at minimum tripping voltage. The minimum trip voltage test is described in a number of international and national standards such as IEC 62271-100 and ANSI C37.09. A user variable output 20-250 VAC or DC is required to ensure suitable operating voltages for testing any circuit breaker.
Programma’s B10E power supply unit can be used to test breaker coils in this manner. It provides ripple-free variable DC voltage that can easily accommodate a high, variable load. Since there is a separate output for supplying spring charging motors, the B10E is ideal for testing circuit breakers where auxiliary voltage is not connected. The compact supply provides reliable assistance to those who do maintenance on high voltage breakers. The control panel’s intuitive layout makes it easy to operate, and the built-in thermal cutout and overload protector make it safe to use.
