Square D, a brand of Schneider Electric, has a full range of control and command products designed to make savings in every area of consumption and ensure compliance with government regulations.
The range includes:
Simple time control
24 hour time switch, repeating the same pre-set switching sequence each day. Battery back up is included to eliminate the need to reset the device every time there is a power cut.
Electronic time control
Digital time switch, 7 day type. These are available with 1 or 2 programmable contacts.The programme can be set to have different switching times each day or day omission if required. e.g. no switching at weekends. The two contacts of the 2-channel version are programmed completely independently. Battery back up stores the switching programme for at least 5 years. These units can also be combined with light sensitive switches for outside or warehouse lighting.
Remote switching using contactors
The use of contactors in the lighting circuits makes the installation easier to install and simpler to calculate. Voltage drop calculations are greatly simplified as the switching circuit is not part of the main circuit. This main circuit is direct from the distribution board to the luminaries. Delay on timers can be used to stagger the switching surges if required.
Remote switching with relays
Impulse relays are rated at 16A and have two stable operating states: with the main contacts open or closed. An electrical supply does not have to be maintained to the coil to keep the contacts closed. A short impulse to the coil will change the contact state. Another impulse will change the contact back. Thus one pushbutton can be used to switch the lights on or off.
