The product has a wide selection of communication port, communication interface with conventional RS232 monitoring software, collocation of humanization design, can facilitate the realization of monitoring the use of UPS, the optional SNMP network adapter card or RS485 card or AS400 card; using LED or LCD display panel display, allowing users to intuitively understand the running status of UPS the. EA900 series UPS with surge absorption, zero power conversion, strong anti-jamming design and reasonable battery management technology, high quality and high reliability, is the best choice for commercial power protection server, PC server and peripheral equipment, communication and network equipment, home office computers and other sophisticated electronic equipment etc..

intelligent management
 It has the function of fault self diagnosis and self-protection. The fault information is clear at a glance, and the maintenance work is easy and quick. Parallel three stage charging design, regular battery self-test, monitoring the battery status.
 Provide RS232/SNMP monitoring interface, monitoring software with power event recording and analysis functions, multiple networking solutions, support TCP/IP protocol, can realize remote monitoring and management

Stable and reliable

 Based on the fully digital control technology of DSP, the control circuit is simplified, and the flexibility and reliability of the circuit are higher.
 The system is more stable, including short circuit, overload, overheat, output over voltage protection and wave by wave current limiting technology.
 Power device design margin is large, the system is more reliable operation.

Green environmental protection

 Built in EMC filter and double surge protection, load power is safer.
 The high input power factor has little pollution to the power grid.
 PFC input power factor correction technology reduces the input harmonic current and reduces the pollution to the power grid.
 Comply with ROHS requirements, meet the high electromagnetic compatibility standard ClassB.

High efficiency and energy saving

 Isolation and filtering of various harmonics and faults in power grid by pure online double conversion design.
 Provide the best power supply quality.
 With the ECO economic working mode selection function, reduce energy consumption, operation efficiency of more than 94% intelligent fan speed regulation, reduce noise and save energy consumption.
 High power density design, small space occupation, higher efficiency of the whole machine.

Flexible and applicable

 Rack type and tower compatible design, 19 inch rack and tower installation arbitrary.
 220V, 50Hz/60Hz power standard can be flexibly set up by panel.
 LCD display mode of random shelf or tower installation, free rotation, convenient for users to view.
 Simply increase the backup time by increasing the battery module.

Special design

 The output power factor is 0.9, which is 13% higher than that of the conventional model.
 Ultra wide grid voltage / frequency input range, convenient for fuel generator access, avoid battery frequent discharge, extend battery life.
 DC cold start function, can use battery boot, convenient emergency standby power supply.
 Switch function of combination key mode to avoid user misoperation.

Intelligent monitoring accessories

 SNMP card: remote monitoring management based on TCP/IP protocol.
 AS400 card: dry contact signal output card.
