Description
Product Overview
BK-G11 Single -Input Single-Output Series Online UPS centers on superior power conversion technology, employing a dual-transformer topology design to establish a comprehensive power purification system from input to output. The input integrates a high-performance harmonic suppressor, effectively filtering over 90% of grid-side harmonic interference, significantly improving input power factor to above 0.99, and reducing pollution to the utility grid.
The inverter core employs SPWM (Sine Pulse Width Modulation) technology and high-frequency IGBT power modules, combined with microprocessor-based digital control. This achieves nanosecond-level pulse regulation precision, ensuring total harmonic distortion (THD) ≤2% in the output waveform. The output is equipped with an isolation transformer, providing not only electrical safety isolation but also completely blocking common-mode and differential-mode interference. This ultimately delivers a frequency-stable (±0.1Hz), voltage-precise (±1%), electromagnetic interference-free, high-purity sine wave power supply to the load.
This series features exceptional load-bearing capacity and broad compatibility, supporting various inductive/capacitive loads such as servers, precision instruments, and medical equipment.
Notes：Industrial Power Frequency UPS is also as known as Uninterruptible Power System, Uninterruptible Power Supply, Transformer Based UPS, Online Low Frequency Uninterruptible UPS.

FAQs
What is UPS?
UPS stands for Uninterruptible Power Supply and is a device that provides a continuous supply of power to protect critical loads from power failures or fluctuations.
What is the main role of UPS?
The main role of a UPS is to provide a backup power source to ensure that critical equipment can continue to operate when utility power is interrupted or unstable, avoiding data loss or equipment damage.
What are the types of UPS?
UPS is mainly divided into three types: offline, online and online interactive.
How to choose the power capacity of UPS?
When choosing the power capacity of the UPS, you need to consider the total power demand of the load, it is usually recommended to choose a slightly larger than the total load power of the UPS to ensure sufficient standby time.
How is the standby time of a UPS determined?
The standby time of a UPS depends on the battery capacity and load power. Standby time usually ranges from 10 minutes to several hours, and the specific needs can be determined according to the actual application scenario.
