High Voltage Solar Cable Connector FDCT-250 Auto DC 250A Amp Contactor

Parameters

Conditions of usage

Overcurrent faults can be divided into acceleration, deceleration, and constant speed overcurrent. It may be caused by reasons such as too short acceleration and deceleration time of the inverter, sudden changes in load, uneven load distribution, and output short circuit. At this time, it is generally possible to extend the acceleration and deceleration time, reduce the sudden change of the load, add energy-consuming braking components, carry out load distribution design, and check the line. If the inverter is disconnected from the load or the overcurrent fault occurs, it means that the inverter circuit is broken and the inverter needs to be replaced.

Overload fault

Overload faults include variable frequency overload and motor overload. It may be caused by the acceleration time being too short, the grid voltage being too low, the load being too heavy and so on. Generally, it is possible to extend the acceleration time, extend the braking time, check the grid voltage and so on. The load is too heavy, and the selected motor and inverter cannot drive the load. It may also be caused by poor mechanical lubrication. For the former, high-power motors and inverters must be replaced; for the latter, the production machinery must be overhauled.

Fault summary

1. In short, you must follow the instructions of the inverter manual when designing, installing and using the inverter;

2. All electrical designers and on-site electrical debuggers can improve the
