Suitable for outdoor street lights, corridor lights, courtyard lights and other LED lighting light controller components, to achieve sunrise bright and out of the surrounding environment, sunset around the dark environment

MOV (Metal Oxide Varistor):

Surge arrestor used to suppress voltage transients and reduces the likelihood of damage to the fixture or the

control caused by voltage surges or line noise.

MULTI-VOLT:

One unit designed to operate within the range of 105-305 volts.

NON-SHORTING CAP:

A device (with a weather seal) that provides an open circuit between line and load when a photocontrol is not

used. Also called an "open cap". Non-shorting caps are color coded red.

PHOTOCONTROL / PHOTOCELL / PHOTO ELECTRIC CELL / LIGHT SENSOR:

A light-sensing device used to control luminaries, which turns the lamp off during the day, and turns the lamp on

at night, in response to detected light levels. A socket for the photocontrol is usually built into, and is part of the

luminaire housing.Photocontrols sense ambient light and turn electric lights (or other electric devises) on when

natural light levels are low, and off when light levels are higher, most commonly, but not necessarily,

corresponding to dusk and dawn.

PLUG:

A cluster of blades fixed to a photocontrol, shorting cap, or non-shorting cap to establish an electrical mechanical connection when inserted into a mating receptacle.

RECEPTACLE:

An outlet that is intended to be equipped electrically and mechanically to receive the plug.

SHORTING CAP:

A device that provides a closed circuit between line and load when a photocontrol is not used. Shorting Caps are

color coded black.

SURGE PROTECTION:

A unit designed to protect electrical devices from power surges and voltage spikes. Surge protectors attempt to

regulate the voltage supplied to an electric device by either blocking or shorting to ground voltage above a safe

threshold. Photocontrols most commonly use MOV's.
