Besides that, it can meet all customers's individualized needs, EA900 II Series 1 ~ 10kVA provide very rich extensible function, users can configure the need flexibly
Output power factor 0.8
PF 0.8 is more suitable for the trend of electrical equipment, and can take more load. With new ECO (Economic) function, system efficiency can achieve 95%, it lower UPS power consumption and save user's cost.
Input PFC
Adopt digital control input PFC technology, Input Power Factor can be more than 0.98, it avoids pollution to power grid, saves energy, and also reduces cost
Digital Control at DC-DC Converter
EA900II 1~3kVA UPS adopt digital control, use Digital Control at DC-DC converter part instead of Analog Control in the past, and it is more reliable.
Green Environment-Friendly Model
EA900II is green model; Comply with RoHS and National Electronics Pollution Management Solutions. Under normal using, it will not cause harm to human and environment
Wide input voltage range
Extremely wide input voltage and frequency range, even in very poor power environment of the remote areas can normally supply the power. It reduced the frequency of battery discharge so that the battery life can be prolonged.
The UPS contain I/P and O/P over-protection, short voltage protection, overload protection, short-circuit protection, inverter over-heat protection, battery low voltage warning protection and battery overcharge protection, etc. Which is the above greatly ensure the stability and reliability of running the system.
Perfect Protection
With bypass function, when the output overload or UPS failure, can turn to bypass without interruption, and supply power to load by mains supply, accordingly provide alarm information.
With input L and N lines detective function, can prevent the danger caused by the inversion of L and N lines.
Cold start and mains power start function.
For emergency status, UPS can start with battery directly when the mains power anomalies.
UPS can start directly without battery; Can be used for high precision stabilizer
Can be used with generator
Wide range of input voltage and frequency, that can effectively isolate the adverse power from generator, can provide clean, safe and stable power supply the load.
Zero switching
Double-conversion online design, that can tracking frequency, phase locked, stable voltage, filter noise, prevent mains interference for UPS output, let the UPS become pure sine wave power supply, to provide more comprehensive protection for the load. Transfer time is zero when the mains power unstable, it can ensure safety and reliability for the load operation
Intelligent Battery Management
It adopts intelligent management technology to charge by three steps, to effectively extend battery life and reduce the number of battery maintenance.
Friendly interface
Powerful extensibility features
Smart slot can provide a wealth of scalable features, you can choose to install UPS smart 2000 monitoring card, SNMP card, RS485, AS400 card, EMD environmental monitor.
