holip drive repair, Shenyang on China (certified), Dalian, Shenyang, drive repair by the China Electric Limited. Shenyang on China Electric Co. (www.zsmsy.com) is specialized in the "high-low-voltage inverter, high and low voltage soft starter, magnetic switches, programmable logic controller (PLC)" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Wei Song. ⑴ drive repair overheating protection fan operation to protect the inverter built-in fan is the primary means of heat inside the box, it will ensure the normal operation of the control circuit. So, if the fan is not functioning properly kebi drive repair, should be protected immediately; ⑵ inverter module cooling plate inverter module overheating protection is a major component of the inverter heat occurs, the inverter is the most important and most vulnerable components. Therefore, all drives are configured in the heatsink pad overheating protection device; ⑶ braking resistor overheat protection nominal power of the braking resistor is selected by short-run. Therefore, once the power-on time is too long, it will overheat. At this point, it should be suspended holip drive repair, be cooled before use. Or use a larger point power resistors; ⑷ cooling duct inlet and outlet must not be obstructed, the ambient temperature may be higher than the allowable value of the inverter. If there are problems, you can call us. Getting drive repair - circuit functions with varistor varistor mainly used transient overvoltage protection mm420 drive repair, but it is similar voltage characteristics of semiconductor regulator, but also it has a variety of circuit elements function, for example, as follows: (1) high-voltage low-current DC voltage component, its stable voltage can be up to several kilovolts or more, which is a silicon regulator can not be achieved. (2) the voltage fluctuation detection elements. (3) DC bottle displacing element. (4) pressure equalization element. (5) fluorescence start element
