* output power: 3500W (input voltage 176Vac~30Vac).

* input voltage range: 85Vac~300Vac (single phase three wire system).

* rated input voltage: 200Vac~250Vac

* maximum static voltage without working time: 415Vac

* input current: <20A @2900W/176Vac

* starting current: <32A

* rated input frequency: 50Hz/60Hz

* output DC voltage range: 42V~58V

* output DC current: 0A~65.5A

* regulation accuracy: less than or equal to 0.5%.

* load adjustment rate: less than or equal to 0.5%

* voltage adjustment rate: less than or equal to 0.1%.

* power factor: greater than or equal to 0.90 (@25%~50% rated output power).

More than 0.90 (@50%~100% rated output power)

More than 0.99 (@50%~100% rated output power)

* efficiency: greater than or equal to 91%

* over voltage protection: input under voltage protection point 80 + 5Vac input overvoltage protection point 305V + 5Vac

* Output Overvoltage Hardware Protection Point: 58.5-59.5V (Output Overvoltage Software Protection Point 56V-59V can be set by monitoring)

* module current sharing error: less than + 0.9A

* cooling mode: forced air cooling.

* safety standards: UL/EN/IEC 60950-2000

* safety requirements: CE/UL/NEBS

* outline size: 87.9mm (high) X85.3mm (wide) X272mm (deep)
