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

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