Legrand, specialists in electrical products and systems, has extended its range of time switches, with the launch of a new generation of digital time switches for industrial, commercial and domestic environments.
“This new generation of digital time switches is designed for precise automation in various applications, including heating and cooling control,” says Luk Ivens, general manager, Legrand Southern Africa. “For example, digital time switches are ideal for controlling air conditioning systems and are also designed to work with thermostats, pressure switches or humidity sensors.
“These energy efficient time switches are user-friendly, reliable and easy to programme and read – even for a non-technical person. The functional programming facility ensures optimum safety, performance and reliability, as well as enhanced aesthetics.”
These programmable time switches, with a digital display, switch an electric circuit – for lighting or heating – on or off at selected times during a pre-programmed time period.
Important features of these new environmentally-friendly time switches are a changeable battery and special adaptation for energy saving lamps. Once the date and time have been sent, no adjustment is necessary. The new design and graphics on the display of these units offers improved visibility. A terminal block with high torque enhances safety of the system.
Legrand’s digital DIN rail mounting time switches with multiple functions and programmes for precise control and optimum flexibility have a unique double display, showing at a glance, the on and off actions, as well as the corresponding days. Additional features include a manual or automatic override ON/OFF facility, as well as a running reserve of six years.
This flexible range encompasses time switches, with a daily or weekly programme for standard or multiple functions, as well as special function time switches with expanded offset programming for astronomical functions. There are also time switches with an annual programme for multiple functions.
Standard units, with a daily or weekly programme, have a clock with a six year working reserve and a precision of 1 second a day. These time switches have an automatic summer/winter changeover and are compatible with alternative energy systems, including solar panels.
Time switches for multiple functions have a daily or weekly programme facility, in 15 languages. This programme consists of an on and off time facility, with assignment to certain days. There is also the option to suspend the programme for a specific period, with the instruction to start up again on a certain date.
The minimum programme setting for this series is one second, with a high precision clock of approximately 0,1 second per day. This range is particularly well suited to irregular cycles in security and industrial installations.
Digital time switches with multi functions and an annual programme have a high precision clock of about 0,2 seconds per day. These flexible units offer about 28 programmes per channel for weekly, annual, astronomical and exceptional programmes.
Only one data key is necessary to create, save, transfer and store programme settings made directly on these new multifunction and multi-programme time switches.
These time switches for distribution board mounting, are ideally suited for OEM’s, as well as panel builders who can pre-programme the time switch when they install it. At a later stage when the panel or product is connected to power, all the end-user has to do is set the real time, which is done simply, like adjusting a digital clock.
Legrand and its distributor network offer an advisory and support service throughout Southern Africa.
