Principle of operation

Fluoresave is a microprocessor-controlled energy saving unit for gas dischargre lighting (fluiorescent, sodium, etc.). Installation is simple and straightforward.

Fluoresave design is based on the operation of the light. When the lights are turned on, the Fluoresave unit supplies mains voltage to the lights for ignition. After a short time period to ensure the stable operation of the lights, Fluoresave switches to a lower energy saving voltage.

The Fluoresave continuously monitors the variation in the output of the current and the input mains voltage. Based on this information, the microprocessor switches the output voltage between the mains (input) voltage and the lower energy saving voltage.

Fluoresave will also have a positve effect on the Cosine Phi (Power Factor) of the circuit.

Fluoresave is fitted with status indicator lights to indicate when the unit is in energy saving mode or to indicate any fault condition, if a fault occurs in the energy saving circuit of the Fluoresave, the microprocessor will ensure that the mains voltage is supplied to the lighting network.

When a Fluoresave unit is installed it becomes operation as soon as the lights are swithed on and dependent on the energy saving time delay setting (3 minutes for Fluorescent & incandescent and 8 minutes for gas-filled lamps), the unit will switch over to energy saving mode.
