Maximum Output Current 3 x 33 amps. Maximum Output Power 22.5 kVA. Correction time 20 m sec (0 to 100% load). Additional Voltage THD 0.25% at output (tested at 100% linear load), (No PWM methods used). Crest Factor > 1: 3 permissible on load current (tested at 100% load). Synchronization Output synchronized to input. Permissible Overload 1000% for 100ms, 150% for 4 minutes, 110% for 10 minutes. Load Types Designed to run lighting, motors, battery chargers, communications equipment, offi ce equipment, SMPS, air- conditioners, compressors, industrial machines, medical equipment and others. Suitable for all domestic, commercial and industrial sites. General Isolation Transformer Connected at input. Delta primary plus earth, 4 wire. Star secondary plus earth, 5 wire. Inter-winding screen earthed at input. Circuit Breakers Input and output circuit breakers to protect against overload and short circuit to both the AVR and the load. Voltage Protection AVS Automatic over and under voltage protection and adjustable re-connect delay, c/w fi ve status LED indicators. Protects load from extreme supply voltage and AVR malfunction. Output Alarm Visual indicator and volt-free contacts if AVR output fails for any reason. By-Pass Automatic by-pass to run load direct from utility power if AVR needs to be taken out of service for any reason. Status indicators for each phase. Technology All solid state (static) switching. Effi ciency AVR: >98%. Isolation transformer: >97% average, >95% worst case Control Microcontroller based control system provides self checks, system integrity monitoring and diagnostic indicators. Control Protection Internal surge arrestors and fi lters in control circuit protect against disturbances.
