Model: RD6018P-W Input voltage range: 7-70.000V Output voltage range: 0-60.000V Output current range: 0-18.000A Output power range: 0-1080W NOTE about the noise about 1200W PSU:There is a high-frequency noise when the switching power supply is unloaded, Due to the large output power range of the product, in order to reduce the power consumption of the switching power supply when no-load, the PWM control chip will jump some control cycles. Assume that the original working frequency is 60KHZ. If there are more skipping cycles, the working frequency will be reduced to less than 20KHZ. This Sometimes a noise audible to human ears is produced. The size of this noise is also related to the production process of the transformer. These are normal phenomena. It is recommended to turn off the AC switch when the product is not in use! If you mind it, please do not buy it.
