Carlo Gavazzi 3rd Gen RSBS Soft Starter AC Motor Controllers

Carlo Gavazzi 3rd Generation RSBS Soft Starter AC Motor Controllers are intended to be used with single-phase scroll compressors or phase compressors. Upon applying the control signal, soft starting is achieved within a 600ms interval. At the end of the soft-start function, semiconductors are bypassed by the electromechanical relays. A bi-color LED indicates the full ON state (green) and alarm indication/alarm type in a red user-friendly flashing sequence. The delay between starts and/or from stop-to-start is indicated via an orange LED.
