The ICRM (included on all MP- DECS-200 standard mounting plates) prevents damage to a protected voltage regulator during power-up by limiting inrush current to a safe level. Without inrush protection, the inrush current is limited only by the level of the power Commissioning and technical supportOur team of field service technicians and engineers is available worldwide to help you through commissioning.

The lower is the impedance; the greater is the risk of damaging the regulator from excessive inrush current. Devices with a pulse-width modulated (PWM) power stage are especially vulnerable to high inrush current due to a large amount of capacitance inherent to the design.
