RFI SUPPRESSION FOR SINGLE PHASE + POWER REGULATORS RFI X10229 INTRODUCTION Phase-angle power controllers generate Radio Frequency Interference (RFI) when the power is switched on during each half-cycle of the mains wave form. In sensitive applications this interference, or interaction with other equipment, must be suppressed to comply with the Electromagnetic Compatibility Regulations 1992 (SI 1992 No.2372). Appropriate suppression may be achieved by the addition of a series choke and capacitor network incorporated in a filter module. The F-type series filter modules have been built to compliment the UAL range of phase angle power controllers. INSTALLATION CE MARKING This product range is CE marked and may be used as a type filter for (CSR, QVR, AVR, FC11AL2, STOM1) and other phase angle applications with appropriate matching current capability (e.g. Stacks and Firing circuits). For classification of `type' filter refer to products family Declaration of Conformity. The standard filter units are to the industrial emission levels (BS EN 55022 Class A).
