LES-MT

Designed for checking and testing the lux level of HID light units

Applications

Application - LES- MT designed and manufactured for Vintec Solution Providers or for Applications where the Main Supply Changes
The solution providers use this controller to test and check the level of Energy Saving can be achieved for his customers required.
The LES - MT reduce the supply voltage to the load by three steps manual selector.
15V or 20V or 25V.
The controller is a 3 phase 4 wire advanced microprocessor controlled energy saving controller specifically designed for checking and testing the lux level of HID light units such as High Pressure Sodium, Metal Halide, Mercury Vapour and Fluorescent Lamps.

Implementation

The LES-MT controller is manufactured with Multi Tap Magnetic Coil.
By the manual selector the installer can decrease the voltage supply by constant value if it is permitted (no fault happened, input voltage is sufficient, there is control signal-"energy saver on" and time delay for lamp heating is over).
After the power is supplied to the controller, the programmed delay time will commence, which is fixed at approximately 6 minutes.
After the timer expires the controller is in "Energy Saving" mode and the output voltage is reduced by ∆U (e.g. if the input voltage is 235V, ∆U=25V, the output voltage will be210V.)
In the case of power failure, after the power return (restart) and all the control signals are still present, the controller provides full voltage to the system and energy saving will begins after the time delay as mentioned above.
If, during energy saving mode, it becomes necessary to restart some or all lamps, this can be achieved by opening the connection to terminals 3 & 4 (disable "Energy Saving" mode).The unit will now supply full voltage until "Energy Saving" mode is again enabled via terminals 3 & 4 and the timer has elapsed.

Selector Switch -S

The Selector Switch "S" has 3 possibilities for voltage supply reduction:
∆U = 15V
∆U = 20V
∆U = 25V

Installation

All LES-MT units are designed for installation within the mains supply cable to the distribution boards of the lighting system. The LES-MT is usually mounted next to, as far as is practicable, the lighting distribution board.
