PHASE ANGLE POWER 25A ac CONTROL MODULE PSR-25 X10205 INTRODUCTION The PSR-25 Power Control Module is a high power, full wave AC phase angle controller in a compact package, capable of regulating up to 6KW (25A) 230V ac. The PSR-25 regulator governs the amount of power supplied to the load, by controlling the phase angle of the AC supply. The low thermal impedance and high electrical isolation provides the equipment designer with a greater flexibility in a wide variety of applications. APPLICATIONS Suitable for quartz lamps, conventional resistive heating elements, including ovens, moulders and dryers and some inductive loads (e.g. transformers and motors). FEATURES • Solid state reliability. • Epoxy encapsulated. • Simple wiring. • Rugged and compact • High current capability. • Internal snubber. INSTALLATION COOLING REQUIREMENTS INSTALLATION SPECIFICATIONS AC line voltage Peak one cycle surge (10ms) I2t for fusing Isolation voltage Max. operating temperature 110/230V +/- 10% @ 50/60 Hz 250A 250 A2s 5000Vrms 65°C Unit limiting RMS current Max peak voltage Minimum operating current Leakage current Manual potentiometer (nominal) Storage temperature -20°C to +85°C Manual potentiometer (nominal) 25A 600Vac 200mA 5mA 250K 1W @ 230Vac 100K 1W @ 110Vac FUSING: It is recommended to use semiconductor (fast acting) type fuses or circuit breakers (Semiconductor - MCB) for unit protection. (See 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. (See Declaration of Conformity).
