SSC-25 United Automation

SSC SOFT START CONTROL MODULE X10336 INTRODUCTION This mains operated soft start power module gives an adjustable ramp up time of between 1 to 60 seconds. The unit also incorporates a 10 50% pedestal, which allows a variable set point of the start up voltage required on certain applications. These units are capable of soft starting loads up to 25A (when mounted on a suitable heatsink) APPLICATIONS Suitable for most resistive and inductive loads within voltage and power limitation, such as heat lamps, fans, pumps and other ac motor loads. RoHS Compliant Directive FEATURES 2002/95/EC Compact and easy to use Adjustable ramp up time Adjustable pedestal Simple wiring High inrush capability INSTALLATION INSTALLATION COOLING REQUIREMENTS SPECIFICATIONS AC system line voltage 110/230V 10% Line frequency 50/60Hz Unit limiting RMS current 25A It for fusing 250 As Unit limiting RMS current 26A Isolation voltage 5000V RMS Minimum operating current 200mA Ramp time 1 to 60 seconds Unit current consumption 20mA dc Max Pedestal 10 to 50% Operating temperature -20 to 85C Storage temperature 0 to 65C FUSING: It is recommended to use semiconductor (fast acting) type fuses or circuit breakers (Semiconductor - MCB) for unit protection. On initial switch on some loads may need an increased Factor of Safety (F of S) for unit and/or device protection. (See the SRA Datasheet for further information). CE MARKING This product family carries a CE marking . These phase angle type controllers require a suitable remote filter. For information see recommendation section and contact our sales desk.
