★ Technical advantages of EA990 series 10-120kVA three-in-three-out UPS

1) Output power factor: 0.9

The output power factor is 0.9, which is 13% higher than the load capacity of traditional machines; for example, the capacity is 30kVA and the active power is 27KW.

2) Modular structure design, maintenance time is close to 0

The UPS shape adopts a tower design, and the internal rectifier and inverter parts adopt a modular design; when the rectifier and inverter are abnormal, the power module can be directly pulled out, which can be directly repaired, saving maintenance time.

3) Optional isolation transformer for output

According to user requirements, an output isolation transformer can be selected inside the UPS.

4) The UPS host can be equipped with a built-in battery

UPS can be built-in 32 12V/7AH batteries, and the cabinet space can be built-in up to 64 batteries.

5) The number of battery cells can be flexibly adjusted

The number of battery cells of the UPS battery pack can be arbitrarily configured and used within ±16/17/18/19/20 cells to ensure that when a battery in the battery pack fails, the faulty battery can be removed without affecting the entire battery pack Note: The battery pack must be even numbered.

6) Parallel battery packs can be shared

When UPS is used in parallel, battery packs can be shared, saving users' battery costs and the floor space and load-bearing requirements of the computer room.

7) 5.7-inch large LCD touch widescreen

Using a 5.7-inch touch screen LCD design and menu structure, various information of UPS can be monitored through LCD, such as: input voltage, frequency, output voltage, current, frequency, active power, apparent power, load rate, floating charge Voltage, equalizing voltage, charging current, charger temperature, battery voltage, battery pack temperature, battery remaining discharge time, battery remaining capacity percentage, battery status, history record.

8) Ultra-wide input voltage and frequency range

The input voltage range is 380V -46%~+36%Vac (half load), 380V -20%~+36%Vac (full load), suitable for environments with large fluctuations in the mains power grid, reducing the number of battery discharges. Thereby extending battery life. The input frequency range is 40~70Hz; it is compatible with various types of generator equipment.

9) Smart battery management

The independent intelligent charging system automatically performs two-stage intelligent charging management on the battery pack. In the first stage, high-current constant-current charging can quickly recharge about 90% of the power; in the second stage, the floating charge is maintained to ensure that the power is not lost. This can well take into account the goals of fast charging and prolonging battery life, and save battery costs for users.

10)Perfect protection function

UPS has various software and hardware protection functions, including various protections and alarms such as overvoltage, undervoltage, phase loss, short circuit, overload, overtemperature, battery low voltage, and overvoltage.

11) Complete power distribution unit

The standard configuration of input, bypass, output, maintenance bypass switches is easy to install and operate, while reducing the cost and floor space for users to purchase power distribution cabinets; in addition, the battery switch requires users to choose an external device.
