System Introduction

BH Series is a double conversion 1/1,3/1 Phase pure online UPS with DSP control. It has been designed for mainstream double conversion system with N+1 or N+X parallel redundancy feature, and manufactured with advanced SMT international standard, which provide outstanding stability and reliability.

High Frequency

System Features

◆ Latest HF switching power supply rectifier and PFC Technology. Input Power Factor 0.99, THDI≤3.5%
◆ Wide Input Range from 160~300Vac on full load (100% Load, If Load is below 50%, it can be reached even equal or lower than
115Vac) On 3 Phase Model Input range is from 304 ~ 478 Vac.
◆ Latest IGBT technology to achieve high overall efficiency up to 90%. Compatible with 220/230/240V and 50/60 Hz Grid Supply
◆ Powerful overload ability with output short circuit protection technology: 1-3 KVA: 120% overloads for 1 minute.150% for 60ms
transfer to bypass and alarm. 6-10KVA: 105-130% overload for 10 minutes, >130% overload for 60ms.
◆ Systems have parallel redundancy feature to increase the system reliability level.
◆ Can be connected with all kinds of generators to save customers costs.
◆ Intelligent temperature compensator and low wave charger can extend battery lifetime.
◆ Intuitive dual LCD and LED display panels, which comprehensively and intuitively reflect the state of power system statuses,
parameters, and other information. Users can modify and operate based on individual needs on these friendly displays.
◆ 19’’ inch Rack Mount structure design. It can be compatible with standard communication cabinet to greatly save data room spaces.

Safe and Reliable
◆ BH Series adapts DSP technology to control UPS all processes (including Parallel function) to increase system reliability.
◆ BH Series adapts sensitive peak current protection circuit to protect the system from damages due to short-circuit, cold load impacts.
◆ 90% of system components are from international famous brands. Systems will fully tested for 24 hours before leaving the factory.

Rich Optional Accessories
BH Series can use SNMP Network Adapter, RS485/Dry Contact, USB port,
and EPO function to build up a remote control and monitoring system.
