Applications

Inrush current limiter (charging resistor) for

smoothing and DC link capacitors

To replace high-power fixed resistors for

capacitor charging

Features

Self-protecting in case of malfunction of

short-circuit relay or internal short circuit of

capacitor

Inrush current limiters are not damaged

when directly connected to Vmax even without

additional current limitation
