The RSBS….V23C.. is a single phase soft starter for 1 phase compressors up to 32 Arms.

The RSBS can limit inrush currents to 45 AACrms (under balanced conditions) and has a maximum ramp-up time of 600 ms. A special function (HP function) allows the RSBS to start compressors, even when pressures are not balanced, by allowing a maximum current of 80 AACrms. Following the ramp-up, the semiconductors will be bypassed by the internal electromechanical relay. The RSBS is rated for a maximum of 10 starts per hour (evenly distributed).

Benefits

• Easy to use. No user adjustments required.

• Space saving solution. Compact DIN or panel mount versions available. Integrated start capacitor.

• Integrated diagnostics. Detection for voltage dips and interruptions. Detection of welded relay contacts.

• Adjusts to load requirements. The built-in HP function ensures that the compressor starts in < 1 second even under high pressure difference during start.

• Reduces light flicker. RSBS reduces the compressor start current by >50% to reduce light flickering.

Features

• Limitation of compressor starting current

• Ramp-up time optimised to 600 ms

• Anti-short cycling function with built-in delay between starts

• Voltage dips/interruptions detection during bypass state
