Psoft Dual Power Flexible Switching Cabinet

Product Overview

The Psoft series dual power flexible switching cabinet is designed to address the issue of continuous power supply for critical loads, preventing production interruptions or voltage dips caused by natural disasters, external faults, unreasonable grid structures, and planned power outages. In continuous production environments, critical equipment is typically powered by two different power sources. However, due to significant differences in load power and varying voltage drop parameters after power loss, traditional dual power transfer switches cannot meet the requirements for continuous operation in terms of switching time. Online UPS systems, aside from their high equipment cost, maintenance expenses, and efficiency issues, are unreliable for motor-type loads. In some cases, improper switching processes can generate large transient inrush currents, potentially leading to serious production accidents and failing to ensure the continuous and safe operation of the power supply system. With over a decade of experience in power switching and exposure to hundreds of switching requirements, Guogao Electric has developed the next-generation Psoft dual power flexible switching cabinet based on seamless switching technology after years of extensive domestic and international research.

The Psoft series flexible switching cabinet focuses on safeguarding critical loads by employing a soft switching strategy that integrates digital phase-locking, power frequency phase-shifting, high-power inversion, and high-power tracking technologies. Combined with proprietary intelligent protection technology, it features functions such as intelligent load tracking, constant torque control, and dynamic soft switching. It integrates multiple functions including flexible switching, comprehensive protection, and remote control, offering unparalleled technical advantages over solutions such as online UPS, EPS emergency power supplies, STS static transfer switches, and dual power switches.

This series of dual power automatic transfer switches can be categorized based on application scenarios into utility mutual backup type, utility-generator type, and AC-DC hybrid type. They are widely used in industries such as petrochemicals, power generation, pharmaceuticals, semiconductors, and digital factories.
