ZH Excellent series Online HF UPS provide effective data-center solution with advanced hardware and rich design features.It is adopted world leading technology and gained numbers of revolutionary technological breakthrough,which has leaded it become a complete
high level reliable product with excellent peformance
Data centre,Telcom, Health Care, Manufacturing
- With a transformer-free design
- sophisticated sensing and control circuitry
- ZH 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 fully 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 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).
- 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 ,ZH series UPS is easy compatible with generator .
- Advanced wireless paralleling technology:
- Parallel with RJ45 network cable only and No need parallal Cards
- Provides industry leading hardware availability
- Modular scalability for capacity
- N+1 redundancy – up to 4 modules in parallel
- Peer to peer paralleling
- Independent load sharing
- No single-point-of-failure
Events log: up to 512events
Dust filter standard equipped
- Default with washable dust filter as pre filtering for wide application
- Non fuel material in case of fire
Flexible installation options
- Full range of accessories for the ZH provides ﬂexible installation options that expedite deployment and save valuable space.
- The aesthetically designed accessories enable coordinated solutions that enhance both safety and reliability whilst reducing installation time and total cost.
- The accessories family includes System Parallel Modules,
- External Maintenance Bypass Switches, External Battery Cabinets, External Battery Circuit Breakers, Top cable Entry Cabinets, Rear Chimneys, IP21 kit (15-200kVA) & Internal Transformer Options (15-120kVA).
