Technical characteristics

Automatic adjustment of three-phase imbalance: after adjustment, the imbalance degree is less than or equal to 15% (adjustable) to realize the average load distribution;

Protection function

Short circuit protection: the device can automatically cut off the power supply in case of short circuit;

Power off locking: the output circuit can be locked on a certain phase automatically to ensure the normal power supply of the line due to the internal failure of the device or the long commutation time leading to the power off of the load;

Under voltage protection: when the line voltage is lower than 338v, the device can automatically lock the output circuit on a certain phase to ensure the normal power supply of the line;

Overcurrent protection: when the load current of the device is ≥ 90a, it can automatically lock the output circuit on a certain phase to ensure the safe operation of the equipment;

Real time detection: when the unbalance threshold is reached, the automatic action can realize the load balance dynamically;

Real time acquisition: three-phase current, voltage, power and other data of transformer;

Reversing time: less than 20ms, automatic switching, does not affect the normal power supply to the user;

Maintenance free: the device is maintenance free, saving labor cost.
