Product Advantages
Strong General Performance
Can be combined with various cabinet types such as MNS, GCK, GGD, etc.
Comprehensive Protection Functions
Equipped with multiple safety protection functions including overvoltage, undervoltage, loss of voltage, overcurrent, phase failure, short circuit, and harmonic protection, effectively ensuring the safe operation of compensation capacitors and other electrical equipment, and extending equipment service life.
Accurate and Safe Control
Utilizes zero-crossing triggering of voltage, with no inrush current during switching on, and zero-crossing switching off without generating high voltage during disconnection.
Intelligent Control and Management
Supports automatic control and remote monitoring, with functions such as data collection, analysis, storage, and report output, facilitating user monitoring and management of grid operation status.
