UPSs Possess High Input Power Factor
Yielding an input voltage range from 160 VAC to 280 VAC, Staco Energy Products’ UniStar P Series single-phase parallel redundant UPSs exhibit an input power factor of up to 0.99 and an input current THD of <5% at 100% linear load from 45 Hz to 65 Hz. The devices uses an ECO operation mode to supply power to load via bypass utility, automatically transfer to inverter supply if the bypass utility becomes out of tolerance, and offer AC/AC efficiency of up to 98%. The units include a programmable frequency converter, an emergency power off (EPO) function, manual maintenance bypass, DSP self-diagnostics, silent fan control, a galvanic isolation transformer, and a cold start function. A LCD/LED mimic panel display shows real-time status and readings, such as operation modes, AC voltage, frequency, battery voltage, load level, and inner temperature.
