VERY HIGH PROTECTION Within a Vision Rack, an Automatic Voltage Regulator (AVR) provides voltage stabilisation and protection from brownouts, sag and surge voltages. The AVR also helps to reduce battery usage and retain their charge for a complete mains power supply failure. Electro Magnetic Interference (EMI) filters provide further protection from spikes and transients. When the mains power supply fails, the load is powered by the inverter and receives a true SINEWAVE supply for maximum power continuity and reliability. HIGH AVAILABILITY A Powershare output socket provides load shedding on mains power supply failure to maximise the back-up time available for critical loads. Predictive battery testing helps to identify potential battery deterioration and failures. Deep discharge protection helps to reduce overall battery aging. VERSATILITY VSR versions include an Emergency Power Off switch for complete electrical shutdown in emergency situations. The “cold-start” function allows a Dialog Vision to start up on inverter when no mains power or alternative power supply is present.
