High reliability

• Wide input voltage range ( -40%~+25%) assure highgrid adaptability and prolong battery service life.

• Dual air ducts design shows bet ter coolingperformance

• Dual power and DSP redundancy design get higherreliability

• Water, Dust and Corrosion resistant coating in all PCBboards

•  Robust EMC Performance due to electromagneticshielding tech

•  Intelligent fan speed control and failure detectionfunction reduces the noise and prolongs fan servicelife

Green power

• High input power factor(Up to 0.999) and low Input THDi: <2.0% at fullload, much less grid pollution and costs

•  Low output THDv: <0.5%, higher adaptability to precision instrument

• High efficiency in online mode >95% and ECO mode efficiency>99%. 50%load >94.74%

• Load Bus sync (LBS) control decrease transfer time and current impact ofdual bus system.

• Self-aging test function without load enables on-site commission

Completed galvanic isolation

• Completed UPS output galvanic isolation for key components from thehigh voltage DC

• Full isolate from the external loads, reduce the harmonic disturbances

• Short circuit protection, restrain the high current puncture to UPS

• No effects to the UPS output performance or reduced impact of theinverter power components whilst supplying specific loads

Intelligent Management

•  Intelligent SNMP and MOD BUS achieves localmonitoring and remote monitor

•  Intelligent battery management, automatic boostingand floating charge control

•  Intelligent fan control according the load capacityreduces the noise and prolongs fan service life

•  Smart programmable dry contact communicationfunction

• Battery self-test function and battery temperaturecompensation function improve the batteryperformance and extend battery use life

Humanized Operation

•  Easy operation with 7 inch LCD touch screen and LED on front door

•  Easy to working modes setting by touch screen: Output voltage, Frequency, ECO mode, charging current and battery cells

•  ON/OFF - Double But ton design to prevent misoperation and touch screen failure

•  EPO (Emergency Power off) button on front panel

•  Large data storage capacity, 10000pcs events logs

More Options
