Soft Starter AC Semiconductor Motor Controller Type RSBS23..A2V.2C24.. • Soft starting of 1-Phase Scroll Compressors • Enclosed solution • Integrated current limit • Rated operational voltage: 230 VACrms, 50/60 Hz • Rated operational current: up to 32A: AC-53b • Integral bypassing of semiconductors • Built-in transient overvoltage protection • Undervoltage protection after ramp up • DIN rail or panel mount • EMC Compliant • Optional auxiliary alarm relay output • Relay Protection • UL, cUL listed • Optimised algorithm for high pressure starts4 • Integrated protection against short-cycling • Voltage dips and interruptions detection • Bi-colour LED for indication of delay between starts and/or alarm Product Description Ordering Code RSB S 23 32 A2 V12 C24 HP This motorcontroller,intendedtobe used with single-phase scroll compres- sors can limit inrush currents to 40AACrms for RSBS2325A2V.2C24.. and 45AACrms for RSBS2332A2V.2C24..1. Uponapplying the control signal, soft starting is achieved within a 600ms interval2. At the end of the soft-startfunction, the semiconductors are bypassed by elec- tromechanical relays. The device rating is based on a maximum of 12 starts per hr.3 Application of supply voltage is indicat- ed by a green LED in the full ON state. Alarm indication is provided through a red LED which signals the type of alarm via a user friendly flashing sequence. Delay between starts and/or from stop to start is indicated via an orange LED. Type Selection Short circuitand Overload protection are not provided with this controller and must be procured separately. Starting and running capacitors are required for controller to operate as intended. The RSBS can also be supplied with an optional auxiliary alarm relay (Option - V22). Note:The main andbypassrelays may be in an undefined state due to transportation.Incasebothrelays are latched in the ON state, there will be a direct on line start of the com- pressor - even without control signal. To avoid the direct on line start, the user may do a first power up with no load connected for a period of ≥ 3seconds.

Applicable to balanced pressure starts in case of RSBS2332A2V.2C24HP 2. For RSBS2332A2V.2C24HP, ramp time is < 1 sec. 3. For RSBS2332A2V.2C24HP, max. starts per hour = 10 4. Applicable to RSBS2332A2V.2C24HP RSBS2332A2V22C24HP ATTENTION: The RSBS soft starter is NOT to be used as a safety device. The RSBS, on its own, cannot guarantee any safety and therefore other components need to be used to ensure that the system operates safely. Note: Power up is defined as the moment when L/L1 and N/L2 are applied to the RSBS. Specifications are subject to change without notice (12.12.2013) 1
