Model Number: PSI-1500E Brand Name: Powerhero Key Specifications/Special Features: CPU control, built-in intelligent software offers highprecision outputPWM technology, pure sine wave output, suitable for all typesof loading includes resistive loads, inductive loads, complex loadsand moreToroidal transformer, in-house toroidal transformer, gives youmore reliable UPS (inverter) with lower exciting currentLCD human-machine interface, input/output voltage andfrequency, battery capacity, loading and etc can be showed onscreenSensitive short circuit protection, when short circuit happens,UPS (inverter) will shut down and giving warning

Sensitive intelligent overload protection, on battery mode,overload more than 110 to 130%, UPS (inverter) will give warning(beeping) for 30 seconds, after 30 seconds, UPS (inverter) willswitch off to avoid damage

On battery mode, overload more than 130 to 150%, UPS (inverter)instantly switches off, on mains power model, overload willactivate the beeping warning until loading is reduced to normalrange

Shorter transfer time: <4ms, make sure your IT applicationswork smoothly

Individual chargers: when main power comes back, battery willbe recharged automatically even UPS (inverter) was shut off,charging current has high and low sort to choose freely

Individual AVR: at mains mode, UPS (inverter) can use asautomatic voltage regulator

Full battery protections: accurate charging and dischargingcurrent monitor and control, intelligent battery automatic-repairfunction, extend battery lifespan
