ZH E Series Online HFUPS 15-400kva

Product Description

Perfect Application:Data centre,Telcom, Health Care, Manufacturing

Advanced Features:

Energy-efﬁcient 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 4-8ms transfer time with 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 fullyDSP 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 reduces slowly and AC current increase slowly.
It can avoid the load all suddenly transfer to line mode. Let UPS be more compatible with generator and smaller capacity to save investment cost.
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

Temperature Compensation function

Full front Service Access design: Reducing the service time ,costs, and space
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 .

Advanced wireless paralleling technology:

Events log: up to 512events

Dust filter standard equipped
