Perfect Application

• Data center ,Telecom, Health Care, Manufacturing 

Energy-efficiency design

• With a transformer-free design

• sophisticated sensing and control circuitry

HE mode:

• High efficiency mode with surge protection up to a 98.5% rating, making it one of the most energy-efficient UPS.

• And it still provides maximum load protection, within 4-6ms transfer time  and surge protection and Unlike most high efficiency UPS in ECO mode.

Real compatibility

 • Active power factor correction (PFC) provides 0.99 input power factor and <3% THDi, thus eliminating interference with other critical equipment in the same network and enhancing compatibility with generators. The ZH is optimized for protecting modern 0.9 p.f. rated IT equipment without the need to oversize.    

True reliability

 • Hot Sync technology makes it possible  to parallel up to four UPSs to increase availability or add capacity.

 • The technology enables load sharing without any communication line, thus eliminating single point of failure.

 • High reliable with DSP controlled and excellent performance, MTBF>20,0000h      

Compact & serviceable design

 • Small footprint occupies minimal floor space:

 • Up to 30% smaller than similar competitive solutions

 • Mean Time to Repair (MTTR) <30 mins

ECT function.

• With its Easy Capacity Test feature, the ZH can test its entire power train under full load stress without the requirement of an external load.

Power Walk-in function.

• When UPS transfer to line mode from battery, the battery current reduce slowly and AC current increase slowly. It can avoid the load all suddenly transfer to line mode. Let UPS be more compatible with generators.

Separate SPS for bypass and main system

  •Besides the SPS with reliable double circuit design but also the SPS of bypass is separated, which can ensure even the main system SPS failed,UPS can transfer to bypass successfully.

ABM battery management

• Intelligent interval  three-stage charging process( constant current, constant voltage,float charging and charger sleeping mode, when battery voltage decrease to a lower level, charger restarts to work).

Advantages:

• Less internal battery corrosion due to resting period

• Monitors battery charge level

• Alarms and back-up time calculation

• Allows users to anticipate end of battery life

• Automatic discharge testing

• Back-up time calculation

• online battery detection function 

Similar modular Class design :

•Power module and battery module design,which greatly reduces the service time, in case of UPS fault

Fault detection provides extra security 

•Detects difference between load fault and upstream source fault

•Downstream fault cleared with increased short circuit capability remaining in high efficiency mode

•Upstream fault cleared by immediately disconnecting from the utility fault

Compatible with generator

•With super wide input frequency range 40-72Hz, and power walking function function,ZH series UPS is easy compatible with generator .

Advancedwireless paralleling technology:

•Parallel with RJ45 cable only and No need parallel Cards

•Provides industry leading hardware availability

•Modular scalability for capacity

•N+1 redundancy – up to 4 modules in parallel

Events log:

•up to 512 events

Dust filter standard equipped

•Default with washable dust filter as pre filtering for wide application

•Non fuel material in case of fire

Graphic LCD display

 • Easy use, and multi language to select,such as :English,French,Spanish,Portuguese,Korean,Russian, Chinese
