1500*1200*1800 mm, 220V/400V/480V/540V/600V/800V
Dongguan City, Guangdong Province, China
Product Description
1. The primary side is 4 loops with 6 contactors are configured each to control the output of 220V/400V/480V/540V/600V/800V separately.
2. Push-button switch is used to control the output of the contactor. Each loop contactor interlock can only have one voltage output.
3. Only the same voltage gear can be used when multiple loops work at the same time.
4. The equipment is equipped with temperature monitoring (winding temperature, core temperature) switching, and the fan is started to cool when the internal temperature is higher than 60 degrees Celsius, and the fan is stopped when the internal temperature is lower than 45 degrees Celsius. Alarm sound occurs when the internal winding temperature exceeds135 degrees Celsius. The transformers automatically shuts down the total input power when the temperature is greater than 150 degrees Celsius.
5. Product total weight 2000KG.
