In the application of the linkage console, the crane resistor is typically used in 50 Hz AC and 660 V low voltage circuitry, and is usually used with the controller instrument to control the start and braking of the crane motor, in order to ensure the normal use of the crane resistor. There are still many restrictions in use.
The first is the requirements for temperature, and can no longer be used in a high temperature exceeding 40 degrees Celsius, and the average daily temperature should not exceed 35 degrees Celsius; according to different regions, the temperature is different. For example, in a cold place, a lower temperature requirement is zero 40 degrees Celsius. Crane resistors are not only required for air temperature, but also have certain requirements for the environment. At a high temperature allowed, the relative humidity should not exceed 50%, but at low temperatures, the relative humidity requirements will be relaxed. When installing a crane resistor, you must pay attention to the installation angle, especially the inclination. Standard conditions is that it should not exceed 5 degrees.
The above is the condition that the use of the resistor needs to meet the conditions, I hope that the above can help you answer questions, and we also welcome your users to come to our factory.
