The SM3185 and SM3215 are part of a range of Handy Mains adaptors which convert battery power into a nominal 230 V ac rms 50 Hertz supply, suitable for operating small power tools, domestic appliances, etc.
Please note that only heavy duty batteries are suitable. These power inverters have a nominal continuous power rating into resistive load of 700 Watts. An audible warning indicates when the battery is becoming discharged. The SM3185 and SM3215 are packaged in a powder coated folded metal box. Input wires enter on one side face and the outlet socket is mounted on the top face.
