The EDERLUX Voltage Stabilizer-Controller is a fully automatic static luminous flux reducer for public lighting

EDERLUX equipment have a dual purpose:
    - Stabilizing the supply voltage in the lighting installations ensuring a tolerance of + 0.2% in the output voltage of the equipment.
    - Enabling the reduction of the luminous level of the installation, reducing the output voltage, in certain pre-established hours.

These two characteristics lead to significant savings in operating costs of lighting installations (+ 40%) both in electrical energy and replacement and maintenance costs.
The EDERLUX family of converters use a simple AC / AC conversion system with pulse width modulation technology. This system, programmed by a microcontroller, generates a sine wave in phase with the input wave of the network regardless of the form and magnitude of the network. The magnitude of the output sine wave can be pre-set linearly from 100V to 220V thanks to modulation techniques and filters, with a harmonic distortion in voltage of less than 2%.
The new Ederlux converters integrate a PWM High Frequency technology based on cutting-edge IGBT transistors, MOSFETs. This technology, developed for the power supply of modern computers and variable speed drives, ensures a faster response to changes in  voltage and load mains, opening a new field in the application for the stabilization of electrical networks and energy saving.
