Constant power purifier (CPP)

Ahmedabad-based Pro-tek Enterprise constant power purifier, which is the power conditioning system that works based on the principle of zero crossing switching technology eliminating surges, spikes, and EMI/RFI. CPP will replace almost all types of power protection equipment owing to its most economical status, light weight, compact size and high efficiency with power saving features. CPP offers ultra high correction rate and output voltage independent of line frequency and free from magnetic interference. Its noiseless operation makes it suitable for all office automation equipment. Technical specifications: Input voltage: 170V to 280VAC, single phase, 50HZ 3 percent Output voltage; frequency stability: 230 V AC 4 percent typical; 47HZ to 53HZ Regulation: 4 to 5 percent (typical) Efficiency (typical): >95 percent Response time: cycle (10 millisecond) Correction rate: 500V/sec (minimum) Output waveform: Sinusoidal Soft turn on delay: 7 Sec (adjustable) EMI/RFI, surge and spikes: NIL (zero crossing switching) Power capacity: 250VA to 5KVA Power factor: 0.8 lag to unity Protections: output voltage OFF at input high/low conditions; overload/short circuit protections; MCB (optionally) Indications: Voltmeter with switch to read input/output voltage Environmental conditions: 0-55C operating temperature; 0 to 95 percent humidity (non condensing); natural air-cooled Salient features: No moving parts, longer life, maintenance-free, acoustic noise-free, light weight and compact size Digital logic IC and solid-state thyristor based circuitry Zero crossing switching technology High peak current, high transient and dynamic response Pure sine wave output with ultra fast correction rate No EM/RF interference Output voltage independent of line frequency Inbuilt surge and spike arrester circuitry Noiseless operation High power efficiency Auto reset and cut-off with switch on delay Applications: PC"s and computer installations LAN/file servers Intercoms/photocopiers/fax and telex Medical electronic equipment Process control instruments CNC based machines Microprocessor based systems Video, cable TV, communication systems
