1.2 ECO mode

Operating mode that ensures ultra-high efficiency while charging the batteries, conditioning the load power factor, and ensuring a Class 1 output voltage regulation.

1.3 Excellent footprint

Small UPS footprint provides maximum usage of valuable electrical room floorspace.

1.4 High efficiency

High efficiency rates that remain stable even at lower operating power levels.

2. Convenience

2.1 Bottom cable entry

Allows cabling from the bottom without the need of additional cabinets providing footprint savings and flexibility to the installation.

3. Availability

3.1 Most advanced and high frequency DSP technology

The high-performance DSP provides UPS more accurate measurements of output voltage and currents, also Fast response to overload and over-voltage conditions.

3.2 Super overload capacity

Long-time working under the load of less than 105%; switching to the bypass in 10min under the load of 105% (inclusive) to 125%; switching to the bypass output in 1min under the load of 125% (inclusive) to 150%.

3.3 Frequency and voltage regulation

Gives higher application availability by correcting poor frequency and voltage conditions without using the battery.

3.4 Advanced electrical features

Excellent power conditioning, very low harmonic distortion through IGBT rectifier, input power factor correction, and high-power efficiency.

3.5 Parallel-redundant capable

Power the connected equipment with multiple uninterruptible power supplies to increase system redundancy and share the common battery packs to reduce the cost. All parameters of the system can be set and adjusted through software. The current sharing adjustment of each UPS can also be completed automatically.

UPS Redundant Parallel Connection

3.6 Flexible design

Available in a wide range of configurations to suit any operating environment, like suitable for various loads: inductive, capacitive, non-linear, etc.

3.7 Generator compatible

Ensures clean, uninterrupted power to protected equipment when generator power is used.

3.8 Dual mains input

Increases availability by allowing the UPS to be connected to two separate power sources.

3.9 Cold start and mains start without battery

In the abnormal state of the utility power, the UPS can be started directly with the battery to meet emergency needs.
When there is no battery, the UPS can be started directly from the mains and can be used as a high-precision regulated power supply.

3.10 Intelligent battery management

Adopt intelligent battery management function (ABM) technology to reduce the frequency of battery maintenance. The advanced constant current and constant voltage automatic conversion charging technology can activate the battery to the maximum and save charging time. Battery capacity prediction, discharge time estimation, low voltage pre-alarm.

3.11 Protection

Various protections such as surge protection and short-circuit protection are available to ensure the reliability of UPS. It is equipped with battery overvoltage, overcharge, and other protection functions to protect the battery from damage to the greatest extent.

3.12 Lithium-ion batteries compatible

It must be set up separately, not included in the standard configuration.
