Made in china MC AH30A 220V lead rail switch box 30A Digital Timer Switch 

When the power switch (electrical time switch) refers to a predetermined time opening and closing circuit, control power load distributed power load control device, also known as the timer switchThe clock. It is the time according to the preset program, cut off or switching circuit to switch system, is used to close the power switch to control need regular operation of electric equipment, measuring instruments, etc.

Specification

The opening of the control of home appliances. When the switch is an electronic circuit with single chip microprocessor as the core of a power switch control device, more time by day or week cycle and control the opening and closing of home appliance. Time setting from one second to 168 hours, can be set to daily "1-4 groups, and a multi-channel control function. Set a long-term effective. Suitable for all kinds of industrial electrical, automatic control of household electrical appliances, is both safe and convenient and save money to save power. Output current can be 10 to 25 a, as well as the normal control of 2200 w to more powerful electrical work. Can also be combined with relay, contactor control other forms of high-power power equipment.

The working principle of electric control switch

Power switch working principle is to use the clock at different times of the electrical contact, timing control the output relay, achieve the goal of on-off circuit on schedule!

When power switch in the application of China

China will main power switch used in the control unit or part of electrical equipment, electricity make these units or equipment to avoid during the peak load of power grid electricity control of electric energy metering device measuring time, to meet the needs of the electricity load adjustment or practicing time-sharing electrovalence at fixed time switch electrical equipment such as street lamps and so on.
