On-line uninterruptible power supply PM 20

single-phasepure sine waveautomatic

Very efficient and reliable double conversion U.P.S. always supply the load devices with or without main presence, no break, no interruption. They are the best solution also in critical main applications, with voltage instability, frequently short or long interruptions, noise and distortion line and supply load with pure sine wave and excellent voltage stability. FEATURES: Full automatic level control and recharge, shut down discharged level, automatic restart. Long life battery on board , professional type, maintenance free. Expand battery facility. Stand-by U.P.S. configuration facility on request. • No break system • Very efficient against micro and LONG power interruptions • Electronic voltage stabilizer and noise filter • Spark lightning protection • Battery expanding facility COMMON SPECIFICATIONS •THD: <3% on resistive load •Overload: 40% for 1 min. •Protections: overload (by pass) •Signalling : Power load bar, overload, low battery, line ON •Input switch: breaker
