Maximum Power: 4000W (connected resistive load) Voltage Regulation:AC 0-220V,Start from AC 10V Dimensions: 85 x 55 x 35MM Protection: Anti-spike, Surge, RC absorption (EOC) How to use: The input is connected with AC 220V, output is connected to the electric stove wire or motor appliances, then rotate the knob for speed, voltage, temperature control. Some Application: Electric furnace, water heater, lamps, small motor, electric iron etc. Attention: Load does not exceed the maximum power, otherwise it will burn module and electrical appliances; use the resistive load as far as possible; reduce inductive and capacitive load power greatly.( it is best to leave more than half of them) Cara penggunaan: Terminal 1 dan 2 : input PLN 220V Terminal 3 dan 4 : output ke beban (load) Jika masih bingung bisa lihat video demo di bawah gambar utama
