RIDEN RD6018 1080W Assembled Set 60V 18A USB AC to DC Adjustable Step Down Voltage Lab Bench Power Supply Buck Converter

Note about the noise about PSU: 1. 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. Since the winding and paint impregnation of each transformer coil are slightly different, the noise of each product's operation is slightly different. 2. There is a loud sound when the fan is running; when the ambient temperature is high, the fan may work even if it is unloaded. 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. NOTE: 1. This Set is already assembled, you can connect AC power directly! Now there are 4 choices(US/EU/UK/AU Plug) , the only difference is the AC cable and input AC voltage request. others are same. 2. This set does not have the WiFi card for APP connection, and does not have battery(CR1220) for date/time display. 3. If you want to install the WiFi card, you need to know that you must install the battery first, if you instll the WiFi card, you cannot remove it and install the battery again. 4. 1200W PSU is 1200W under 220V AC input, but it is only 1000W under 110V AC input, please be careful when choosing PSU.
