JD2529800Features:1. Output voltage: Light in the measurement of the output voltage and the input voltage is the same,needs to be connected to more than 20 w load can measure the output voltage.2. Alternating current (ac): The output is also an alternating current, it is not a direct current (dc).3. Work load energy impedance: The work load energy impedance is 4000 W, inductive load is 1/3 impedance load, load impedance refers to light, heat wire, etc, inductive load is only series motor, etc.4. Metal material:The metal Housing of electrical equipment provides security for you.5.Wide application: It can be used as power supply for large electrical devices of 10000W, enough for household appliances or for small factory. Description:It could be widely used as heat controller on electric stoves, water heaters, light dimmer on lamps, speed controller on small motors, or temperature controller on electric soldering iron.
