Range of products for energy efficient designs

28 May 2008 Power Electronics / Power Management

Legrand’s range of energy saving electrical products and systems, designed to minimise the effects of power outages, includes emergency lighting devices, energy saving occupancy sensors and surge protection units.

"These emergency lighting systems and occupancy sensors, which improve safety and minimise inconvenience when power goes out, are enhanced by surge protection units designed for localised protection of the mains supply of computer and electronic equipment against voltage surges and lightning," says Timothy Mountjoy, national sales manager for Legrand South Africa.

Legrand's emergency lighting devices, which automatically light up in the event of a power failure, will last for up to three hours, giving a light output of up to 140 lumens. There are three types of emergency lighting in the range - non-maintained, maintained and combined. For South Africa's current power situation, the company recommends the non-maintained unit, as it is off when power is on and comes on when the power fails. This range includes basic units, as well as decorative fittings for commercial buildings and hotels.

WattStopper occupancy sensors, based on passive infrared and ultrasonic technologies, monitor and control lighting, occupancy and motion, saving users hours of wasted lighting each day. These occupancy sensors are designed to switch lighting off in unoccupied areas, or to automatically turn it to a lower level.

WattStopper Smartset technology means that no adjustments are needed at installation. Smartset monitors usage patterns and automatically adjusts the time delay and sensitivity settings for optimal performance and maximum energy efficiency.

Mosaic surge protection devices, which have a nominal discharge current of 20 shocks at 2,5 kVA and a protection level of 1,5 kV, can be connected to a socket. Display of operation is evident by a voltage surge protector indicator. Two models are available - one which consists of a voltage surge protector and the other, which offers greater protection against lightning and voltage surges, is fitted with a filter. A replacement module which must be fitted after lightning or a surge, is also available.
