Memory Off Function: Automatically saves a value, automatically starts the last set value after power on When testing, you must connect to the download! The EU plug can insert for this Socket Model: GT-10000W (knob section) Input voltage: AC220V Output voltage: 0-220V adjustable (output voltage is less than input voltage) Maximum power: 10000W (when inputting 220V) Voltage regulation range: 0-220V stepless adjustable (with load conditions) Really achieve step-down to 0V, boost 0V Rated current: 25A Maximum current: 45A Product features: zero hysteresis, zero delay, with peak voltage absorption circuit to effectively protect high power thyristor Anti-surge, anti-spike, RC absorption multiple protection Product size: length 13X width 7.5 height 6cm installation size: length 10.5X width 8.5CMX 4 Precautions and instructions for use 1. When the load is idling, the output voltage is the same as the input voltage. It must be connected to a load of 10W or more to measure the output voltage. 2. Input AC power, the output is also AC, not DC. 3. The above mentioned 10000W refers to the power when working under resistive load, and the inductive load is 1/3 of the resistive load. The resistive load refers to the electric lamp, the heating wire, etc. The inductive load refers to the series excitation motor, etc. There are electronic smart products that are used with caution. 4. Metal enclosure electrical appliances, please safety grounding
