1-phase compressor soft starter
Benets
• 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 dierence during start.
• Guided model selection. Easy to use online
selection tool to select the appropriate soft starter
model depending on the compressor brand/model.

• Reduces light icker. RSBS reduces the compressor
start current by >50% to reduce light ickering.
Description
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).
