S380380C-1

Auxiliary Bypass Unit

Product Introduction

S380380C-1 is a control module designed in response to the requirements of PCS system. Its main functions include: system status detection, logic control and protection; responding to the BMS to achieve rapid control and protection; responding to the EMS to achieve power dispatch; linking the communication between the monitoring system and the power module; on-grid/off-grid mode switching control; current distribution control in parallel; and rapid response to power grid mutations. ICU250K380-S/ICU500K380-S power module can realize 10ms on-grid/off-grid switching. In on-grid mode, the N line of the power module is disconnected from the N line of the grid; in off-grid mode, the N line of the power module is connected to the N line of the grid. It is featured with high reliability and miniaturized design, and suitable for on-grid and off-grid energy storage systems.

Miniaturized structural design, suitable for narrow installation space of the electrical cabinet, convenient for product maintenance
Modular design, suitable for fexible energy storage system building
Fast detection speed, strong anti-interference ability, strong signal processing ability
High integration and high reliability
