AC220-380V wide voltage wireless two-way remote control switch, using a professional switching power management chip, power supply voltage stability, completely solve the resistive buck and use the power supply voltage instability, resulting in the phenomenon of the whole switch is not stable. This remote control switch adopts 30A relay, can learn more than one remote control, operation is simple supporting flexible; point, self-locking, interlocking can be arbitrarily for ease of use, in addition to the new manual mode of operation. Suitable for many fields and uses. Working voltage: AC220-380V Maximum power: 3000W Standby current:less than equal 15mA Signal sensitivity: -105dBm Modulation mode: Working Frequency: 433MHz Colour:White & Yellow Note: Due to different production batches, there are differences in label printing, which does not affect use. Material:Plastic Package Contents: 1 * Controller 1 * Remote control 1 * Antenna Only the above package content, other products are not included.
