B 2-10K Low Frequency 1/1
Download
Ranging: 2VKA~10KVA
Working mode: Low frequency online
Application: Workstation
                       Network Server
                       Computer Framework
 
·Mono-phase input/ Mono-phase output
·Low frequency design
·On-line double conversion technology
·Central control management
·DC start
·Hot parallel system
·Perfect protection

Features:
1. Online double conversion, output of UPS is sine wave, which is against voltage disturbance.
2. Equipped with isolated transformer, strong ability against disturbance, provide more  security.
3. Good compatibility of load, meet all kinds of working state.
4. Wide input voltage range, avoid frequent shift to battery mode, applicable to environment of bad electricity.
5. Wide input frequency range, make sure normal working if connect with fuel oil generator.
6. Advanced security function for output overload, short circuit, high temperature of inverter, low voltage& over charging of battery, make the system more stable.
7. DC start-up can start UPS without power from mains.
8. LCD displays working state of UPS.
9. With RS232, SNMP interface, monitoring UPS working state.
