Line-interactive UPS 400VA~3000VA

Main Features
1. Microprocessor-based digital control.
2. Boost and buck AVR for voltage stabilization.
3. Auto sensing frequency.
4. Wide input voltage range.
5. Power-on self test.
6. Cold start.
7. Auto restart when mains power is restored.
8. Auto track mains phase to ensure that inverter output voltage has same phase with utility voltage, reducing transfer time and peak surge.
9. Intelligent battery management: battery temperature compensation to extend the battery life; three-stage charging to shorten recharge time.

Technical Parameters

UPS Overview

DSP Technology: The advanced DSP digital control technology enable UPS more stable performance.

Environment Friendly: This UPS is eco-designed and manufactured to meet the China local pollution control requirement of Electronic Products, which means it will cause no harm to environment and human beings in normal usage.Active input power factor correction (PFC): Digitalized control of the PFC enable the UPS to keep input power factor above 0.99 to prevent possible electric grid pollution and meanwhile mostly save the cost.Widened range of input voltage and frequency: We intentionally widen the range of input factors to make sure the UPS can apply to various environment, which will effectively sustain the battery charging even in unstable power environment so that the service life of the UPS copd be obviously prolonged.Zero power switch delay: When the utility power fails, UPS will automatically switch from AC mode to battery mode with no delay, which will ensures stable power supply of operating system.Adaptive Load Management: This technology allows the UPS to be set up at a fixed 50Hz or 60Hz output, while it also can intelligently monitors power usage and automatically sheds and reconnects loads in order to prevent generator overload.Sufficient Expansion Slots: The pre-allocated smart slots enable flexibility in choice of USB cards,AS400 cards, CMC monitoring cards, SNMP cards, RS485 cards and EMD environment monitoring cards.The load power factor is 0.8: it adapts the features of most current electric equipment and elevates the load-bearing capacity of the machines.Support the Generators: The wide range of input voltage and frequency can effectively separate the harmfp electric wave produces by the generators and provide safe and reliable power supply.Large-screen LCD
