1. high new 2. Small size, light to carry, powerful easy to use. 3. High-power thyrist voltage regulat, stepless adjustment, helps to adjust speed, temperature, voltage light. 4. switch control, freely control the input power cut off the power. 5. The shell is fireproof heat preservation, high temperature resistant, rust proof, high pressure resistant durable. 6. Adopt multi-functional industrial plug, thickened copper design, good contact, safe reliable. 7. Quiet wk, energy saving, stable anti-noise, wide range of use. 8. Applicable to electrical components, such as: electric furnace, water heater, heat transfer lamp dimming, small mot, electric welding temperature, etc. Input voltage: AC110-220V Output voltage: 0-220V Maximum power: 4000W Voltage adjustment range: 0-220V Rated current: 9A Maximum current: 18A Precautions Instructions f Use 1. When the machine is empty, the measured output voltage is a virtual voltage, a load of me than 20W must be connected to measure the crect output voltage. 2. Input AC, the output is also AC, not DC. 3. The 4000W mentioned above refers to the limit power when wking under resistive load. The inductive load is 1 or 3 of the resistive load. The resistive load refers to the tungsten filament lamp, heating wire, etc., the inductive load refers to the series excitation mot. etc., use with caution in electronic products with circuit boards. 4. This product is a metal shell must be safely grounded Tips: The product may be updated constantly ,Due To Different Batches, The Actual Product May Have Slight Differences Col Differences, Which Does Not Affect Use Plug Type :EU Plug,it applies to Indonesia, Germany, France, , Italy so on. Voltage: AC 220V Colour:Black Material:Metal Package Contents: 1 x Mot govern Only the above package content, other products are not included. Note: Light reflection different displays may cause the col of the item in the picture a little different from the real thing. The measurement allowed err is 1-3cm.
