Functional Features

Voltage stabilization function: It can provide stable power output in situations such as power fluctuations, voltage dips, high voltage, surges, spike pulses, harmonic interference, etc., ensuring the normal operation of backend equipment.

Protection function: It has protection functions such as overvoltage, undervoltage, overload, short circuit, phase loss, and reverse phase (three-phase). When abnormal situations occur, it can quickly cut off the power supply and protect the safety of the equipment.

Bypass function: When UPS fails or requires maintenance, it can switch to bypass power supply without affecting the normal operation of backend equipment, and various protection functions are still effective in bypass state.

Intelligent monitoring: Some bypass cabinets are controlled by advanced digital signal processors (DSP), which have LCD screens to intuitively display the current voltage and current, real-time monitoring of power operation status, and have fault recording and storage functions. They also reserve RS485 communication interfaces for networking.

precautions

Selection and matching: Based on the actual power, voltage, frequency, and other requirements of the load, select a bypass cabinet with appropriate capacity and parameters to ensure stable and reliable power supply to the load.

Installation environment: The bypass cabinet should be installed in a dry, ventilated, and non corrosive gas environment, avoiding direct sunlight and humid conditions, while ensuring the stability and safety of the installation location.

Maintenance: Regularly maintain the bypass cabinet, check the operating status of each component, clean dust and debris, and ensure that its performance is always in good condition.
