VARIABLE AC REGULATOR QVR/RFI 17A QVR-s/RFI 17A UP TO 17A WITH RFI SUPPRESSION X10299 INTRODUCTION These variable phase angle power regulators are robust and compact units for 23 0V, up to 17A, which are ideal for controlling single phase mains driven loads. They give fully adjustable voltage output from 0-98% and the large triac enables the unit to handle high inrush currents with ample safety margin on industrial installations. These units incorporate their own RFI filter network to comply with EMC Regulations (Class A). APPLICATIONS Suitable for quartz lamps, or any conventional resistive heating elements in series or parallel configurations. Applications including ovens, moulders, dryers and some inductive loads, for example transformers and motors. FEATURES R o H S C o m p l i a n t Directive 2002/95/EC Integral RFI network. ON/OFF switched version (QVRS) Infinitely variable 0-98% output. Single hole fixing. Rugged and compact Designed to maximise thermal dissipation INSTALLATION CONNECTIONS AND DIMENSIONS INSTALLATION SPECIFICATIONS Triac limiting RMS. On state cycle 25A Isolation voltage 2500V rms 2 2 Peak one cycle surge (10mS) 320A I t limiting value for fusing 112A s Max forward volts drop at 10A 1.5V Mains supply tolerance, within 10% 230V/110V ac Max load at 20C ambient (without extra heatsink) 10A Max recommended unit temperature 65C Mains frequency 50/60Hz Max recommended unit temperature -20 TO +85C FURTHER DIMENSION Shaft diameter 6.3mm Shaft projection from bush 13mm/SW 8mm Bush length 5mm Fixing hole diameter 10mm FUSING It is recommended to use semiconductor (fast acting) type fuses or circuit breakers (Semiconductor-MCB) for protection. On initial switch on some loads may need an increased Factor of Safety (F of S) for Unit and/or Device protection. See SRA Data sheet for further information. CE MARKING This product family carries a CE mark and incorporates a filter (Standard type to emission levels BS EN 55022 Class A - Industrial) to address the EMC directive.
