The KLSP-03A / KLSP-06A module was designed to protect the power supply of electronic devices against electromagnetic disturbances, lightning and overvoltage in the electrical system. Special varistors provide protection in the case of dangerous asymmetric voltages, which often occur simultaneously with symmetrical voltages. The filter absorbs high pulses very well, with an extremely short response time. This module has been specially designed to be used with the KOBER KMCS cascade module. Dual filter for improved performance. Compatible with the DIN-RAIL rail system.
