Legrand AlphaRex 3 and MicroRexadvanced programmable time switch technology

Legrand's AlphaRex³ and MicroRex me switches are designed for easy programming and ensure high-clock precision in industrial, commercial and domesc environments. Legrand devices, with advanced me switch technology, are used to switch an electric circuit on or off at selected mes during a pre-programmed me period. These analogue and digital me switches also have an automac return facility and a permanent forced switching on or off override control.

The AlphaRex³ series has a user-friendly standardised text guided programming facility, with a high-resoluon digital display and backlight. There is a standard, single data key for all devices in this range to allow quick and easy transfer of programmes to other me switches and for creang back-up copies.

Programming with clock precision to the second is controlled directly on the me switch, or outside the distribuon board using a PC and Legrand's AlphaSo programming soware. Other features include an EEPROM memory, which prevents sengs being lost and the facility to programme the clock prior to despatch. Once the unit has been programmed, the informaon will remain installed even if the switch is not connected to power. The baery can be removed without having to uninstall the me switch from the distribuon board. AlphaRex³ me switches are available with standard and mulple funcons, with a daily or weekly programme facility and a clock working reserve of six years. Typical applicaons for this series include industrial pump staons, security alarms, indoor and outdoor lighng, air condioners, heang and venlaon systems and swimming pool heaters. These me switches are also compable with alternave renewable energy systems, like photovoltaic panels.

MicroRex me switches offer easy plug and play installaon for daily and weekly programming. By simply seng the analogue switching dial during start up, the me is automacally set using the fast-run mode. In the event of a power failure, the me is automacally reset.

MicroRex devices, with analogue and digital dials, are 24 hour and seven day me switches for DIN rail and wall mounng, with a five year running reserve. These units have the capability for mulple programmes, which ensures opmum me seng flexibility. MicroRex me switches have an

LED status indicator, a precision clockwork of 0.2 s/day and are controlled by either a quartz or synchronous motor. For increased safety and user convenience, there is an automac and manual and advance/over-ride facility

The MicroRex series is designed for dependable use in many applicaons, including periodic lubricaon of machines or regularly repeated switching of pumps, feed conveyors and sprinkler systems. This device is also suitable for short periods of controlled defrosng.

Other me switches in the Legrand range are designed for precise control in security installaons – for access points; electric fences and alarms – as well as for use in industrial installaons, including pump staons, filters and conveyors. Legrand me switches are also used for the lighng of commercial boards and signage, as well as for street lighng. Time switches in agricultural applicaons are used for irrigaon and sprinkler systems and for cyclical programmes, like animal feed systems.

This range is available naonally from Legrand's distributor network and a technical advisory and back-up service is also offered.
