Technical content
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). PHASE ANGLE POWER 25A ac CONTROL MODULE PSR-25 X10205
FEATURES
- Solid state reliability.
- Epoxy encapsulated.
- Simple wiring.
- Rugged and compact
- High current capability.
- Internal snubber. INSTALLATION

CODE IDENTITY DESCRIPTION X10229 RFI Filtering recommendations - addressing the EMC Directive X10213 ITA Interaction, uses for phase angle and for burst fire control. X10255 SRA Safety requirements - addressing the Low Voltage Directive (LVD) including :- Thermal data/cooling ; “Live” parts warning & Earthing requirements; Fusing recommendations. AP02/4 COS UAL Conditions of sale NOTE It is recommended that installation and maintenance of this equipment should be done with reference to the current edition of the I.E.E. wiring regulations (BS7671) by suitably qualified/trained personnel. The regulations contain important requirements regarding safety of electrical equipment. (For International standards refer to I.E.C directive IEC 950). 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). 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).
