TPSR-25 COMPACT PHASE ANGLE 25A AC REGULATOR X10284 INTRODUCTION The TPSR series of Solid State temperature controllers are designed to regulate the fan speed in heating, ventilating and air conditioning systems. The thermistor replaces the conventional thermostat thus giving continuous proportional control of the blower speed in response to the temperature. The TPSR also incorporates a set minimum fan speed, for the gentle circulation of air through the heat exchanger and to provide protection of the motor bearing. APPLICATIONS Suitable for quartz lamps, conventional resistive heating elements, including ovens, moulders, dryers and some other inductive loads. FEATURES Solid state reliability. Epoxy encapsulated. Simple Installation. Rugged and compact High current capability. RoHS Compliant Internal snubber Directive 2002/95/EC INSTALLATIONINSTALLATION COOLING REQUIREMENTS TPSR SENSOR ASSEMBLY RT CURVE 250,000.00 200,000.00 150,000.00 100,000.00 50,000.00 0.00 0 TEMPERATURE ( C) SPECIFICATIONS AC line voltage 230V +/-10% Line frequency 50/60 Hz Thermistor See X10308 Triac limiting RMS current 26A Peak one cycle surge (10ms) 250A Max peak voltage 600V ac 2 2 I t for fusing (10ms) 250 A s Minimum operating current 200mA Isolation voltage (for 1min) 5000Vrms Leakage current 5mA Unit current rating 25A Manual potentiometer (nominal) 250K 1W 230V ac Operation temperature 0-65C Storage temperature -20C to +85C FUSING It is recommended that semiconductor, fast acting type fuses or circuit breakers (Semiconductor - MCB) be used for unit protection. On initial operation 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 marking. These phase angle controllers need a suitable remote filter. For information see recommendation section and contact our sales desk.
