◆ On-line static bypass design. Static bypass switch have bypass overload and fault protection. ◆ high operating efficiency with a. IGBT(Insulated Gate Bipolar Transistor) technology ◆ Wide input voltage range. reducing battery working time and extending the battery life The advanced DSP-based full digital control technology effect including UPS operation, battery management, automatic restart and shutdown, and provide real time mains and load readings. Battery management. programable battery test both weekly or monthly for 6 seconds Fault history event record. Fault / Alarm History with "date" & "time" of each event ◆ High reliability and low maintenance. Manual maintenance bypass, and MTBF(mean time between failure) of 200,000 hours, and MTTR(mean time to repair) of 15 minutes, slide out battery trays and redundant ventilation for battery thermal stability. ◆ ECO mode. 3W3 is also ?riendly?to the electrical supply, taking 95% utility power.3W3 establishes a new benchmark in uninterruptible power. The modern, compact design tackless power problems in a unique and innovative way to provide perfect protection for computer networks, process and medical control equipment, and any other mission critical applications. ◆ LCD display and LED mimic diagram provide clear and timely information on UPS operating status such as UPS voltage and current of input and output, peak input current, charging voltage and current and voltage after PFC. ◆ Two RS232 interface ports, and a remote port including UPS-OFF, bypass and EPO inputs.Internal SNMP card slot
