★ Technical features of EA900G4 series 6-20kVA UPS Using DSP digital control technology

PFC rectifier, battery boost, charger and inverter all adopt advanced DSP digital control technology, which effectively improves product performance and system reliability, and achieves higher power density integration and miniaturization.

The load power factor is

The power factor is increased from 0.9 to 1, to achieve a stronger load capacity, which is 13% higher than that of traditional products.

The input power factor is as high as 0.99, high efficiency and energy saving

Using active power factor correction (PFC) technology, the input power factor is as high as 0.99;

The efficiency of the main circuit can reach up to 95%. In the case of good power grid conditions, the working efficiency can reach 98% when the ECO mode is turned on.

Intelligent fan speed adjustment

The fan speed can be automatically adjusted according to the load status, reducing energy consumption and noise, and prolonging the service life of the wind.

Flexible battery configuration

The number of battery cells is flexible and adjustable, and supports 16-20 cells to meet the different needs of users.

Wide input voltage frequency range

Extremely wide input voltage and frequency range, suitable for various environmental power grids, even in remote areas with harsh power environment, can supply power normally, and linearly derate when input low voltage, reduce battery discharge times and extend battery life.

Dual input design, can support different sources of main and side, improve the usability of bypass and system reliability.

Friendly man-machine interface

LCD+LED display, combined with multi-function button operation, friendly man-machine interface, easy operation, powerful background software support, rich UPS information display, and various operations such as parameter setting.

Inverter mode

Support 50Hz input/60Hz output or 60Hz input/50Hz output frequency conversion mode to meet the special needs of users.

50/60Hz power system adaptive

Automatically recognize and adapt to 50Hz/60Hz power system to meet different power system requirements.

Perfect protection measures

Complete software and hardware protection functions, super self-diagnosis function, integrate AC input over-voltage and under-voltage protection, short circuit protection, output overload protection, over-temperature protection, battery low-voltage and fan failure protection and other multi-function protection in one, extremely The earth guarantees the stability and reliability of the system operation, and has a rich historical record, which is convenient for query and maintenance.

Cold start and mains start function

Using the battery to start the UPS directly in the abnormal situation of the mains power supply to meet the emergency needs;

Automatic switch function

It has an intelligent automatic switch function, which can realize automatic switch according to the load set by the user.

Self-aging function

The self-aging function can be set to facilitate customers to perform aging test on the machine before connecting to the load on site. Without renting any dummy load and cable connection, it can simulate the UPS system running with full load, saving customers investment.

Intelligent battery management

Adopt intelligent battery management technology, automatic floating charge control, charger dormancy control, which can improve the reliability of the charger, increase the battery life by 50%, and reduce the number of battery maintenance;

It has alarm functions such as reverse battery connection, charger failure, battery no, battery overcharge, low battery voltage, etc.

Powerful extensibility function

Standard RS232 and smart card slot, optional parallel function, battery temperature compensation, SNMP card, USB, RS485 card, dry contact card and SMS alarm;

Support RS232, USB, SNMP, RS485 and dry contact a total of 5 communication interfaces to monitor the operating status of the UPS. Among them, the SNMP card can realize remote network monitoring and management, and through the monitoring, regular battery self-checks can be set.
