To ensure uninterrupted and consistent operations in your production lines, it is crucial to maintain secure power quality and prevent voltage sag, swell, interruption, and fluctuation.
A recommended solution for high reliability and robustness, even during motor switch on and off, is the transformer-based Uninterrupted Power Supply (UPS).

The transformer based UPS

Is designed to withstand inrush currents, making it the ideal choice for industrial manufacturing plants and other sensitive equipment.

Protecting production lines from power disturbances can prevent costly downtime and help improve production output.

By implementing a UPS, you can rest assured that your facility is receiving secure and reliable power, allowing you to focus on your core business operations.

Intelligent fan speed control
Perfect hardware and software protection

Digital control

It adopts advanced DSP control technology that effectively improves the product performance and system reliability.

Rear air draft radiating

Rear air draft can be used to effectively reduce the corrosion from the dust, water and other impurities on power lines and internal components and improve the reliability of UPS in harsh environment.

Intelligent fan speed control

The fan speed can be controlled intelligently according to load, which can reduce the noise around the device and extend the service life of the fan.

Perfect hardware and software protection

Integrating a variety of functions, such as AC input over/undervoltage, overload, short circuit, over temperature, IGBT current-limiting protection, battery undervoltage alarm and battery overcharge protection. This securely guarantees stability and reliability of system operation.

Miniaturization design Adopting full digital control technology; realizing device miniaturization and reducing the occupied area via optimizing circuit structure and duct.

High Availability

Wide input voltage range
High output power factor
Fast and stable charging
Cold start function
Zero transfer

Wide input voltage range Input voltage 165V~275VAC, frequency 45Hz ~55Hz. It is suitable for harsh grid environment, greatly reduce the number of battery discharge, extend the service life of the battery and match the small capacity generator easily.
High output power factor The output power factor is 0.9, which can take more 12.5% loads than the conventional products.
Fast and stable charging Optimized charging mode makes the charging speed doubled. Floating charge and equalizing charge voltage are settable, which can match more battery brands and extend the service life of battery.
Cold start function When mains power is not available, the inverter can be started by battery to meet the requirement of emergency application.
Zero transfer Online double-conversion design; the transfer time of UPS power supply mode is zero when the mains power is instable, which effectively ensures the safety and reliability of load operation.
