Timer lighting controls – an essential device for homes, villas, shopping malls, outdoor advertising. It automatically turns the light on and off (lights, lights, billboards) at specified time. Many timers today are equipped with features motion sensor and photocell, which when it gets dark automatically turns on the lights.
For one of the three lamps are enough devices with a maximum load of 6 Amps, powerful spotlight will monitor the timer to 10 Amps, and to optimize the operation of lighting fixtures throughout the house, or in a few street lights should buy a timer no less than 20 Amps. The exact maximum load, which is necessary to sustain your timer is calculated as follows: fold the power of the appliances (in Watts) that will connect you divide by the standard voltage is 220 Volts and get the perfect amount of Amps.
Mechanical lighting control devices «distinguish» only time of the day, more expensive electronic «know» days, weeks and even months. During a power failure mechanical timers stop in time, and electronic for another six months will be able to tell the time.
The device can be used to adjust the light in the garden, around the house or separate rooms, stairways, tanks. Travel lovers, whose house is often empty, use a timer-guard. It randomly turns on and off the light in the room and simulates the presence of people.
Normally, the common lighting control devices, the top power, and bottom contacts is switching, that is, to directly control lighting. If the terminals are arranged in one row, the first two are responsible for «zero» and «phase», the remaining terminals are responsible for enabling, disabling, and switching contacts. The blue wire traditionally means «Zero», red «phase», the brown wire is responsible for access to the bulb. Jumper between the group of terminals «zero-phase» and a group of contacts also have to be supplied with power.
