The sheet metal chassis is usually designed with a circuit breaker element. It is connected to the line power supply, which can help the frequency conversion control cabinet to complete the circuit's on-off operation, and can provide protection when the circuit and the inverter are short-circuited or overloaded. In addition, the frequency converter cabinet can also cut off the power supply during motor maintenance to ensure the safety of operators.

The chassis of the sheet metal cabinet houses all kinds of electrical components, including the inverter, in the cabinet. This reduces the degree of influence of the external environment on the electrical components, reduces the degree of contamination of the electrical components due to the environment, and reduces the operation of the inverter cabinet. Personnel are at risk of electric shock and therefore have a good safety protection effect.

The appearance of the chassis of the sheet metal cabinet is made by SPCC high-quality cold-rolled steel plate. The structure is stable. The maximum static load weighing is 800KG. The appearance design is noble and elegant, the craftsmanship is superb, the dimensions are precise, and the atmosphere is very contemporary; the slopes on both sides of the equipment installation are more beautiful. , generous; can be closed at the bottom of multiple alignment channels, bottom wiring hole, the size can be adjusted as needed; the bottom of the mounting hole optional casters to make transport more convenient and flexible; colorless transparent glass front door, glass around Screen printing black mesh; strong and efficient parallel connection device; removable upper mounting plate on both sides, easy to enter the upper part of the cabinet; removable front and rear doors improve the flexibility of the cabinet; multiple grounding screws inside the cabinet; Full range of optional accessories.

The heat generated by the inverter in the sheet metal chassis is caused by internal losses. The inverter must be cooled, and we usually use a fan to dissipate the inverter.
