Electronic Control Gears:
Electronic Control Gears generates high frequency alternating voltages
with frequencies of about 30~70 KHz, because of which the luminous
efficacy of Fluorescent lamps is increased approx. By 10% vs. 50/60 Hz.
Operation of Inductive ballast, thus the High frequency allows to lower
the system rating without reducing the luminous flux of the lamps.
Energy savings:
In order to compare the power consumption and the efficiency of fluorescent
lamp circuits, the system consisting of the lamp and ballast has to be regarded,
in consideration of the achieved luminous flux of the lamp. For ex. A
fluorescent
lamp rated as 36 watt, requires system power of approx. 48w, when it is operated
via conventional inductive ballast. When using an electronic ballast an
electronic
control gear unit the same system rating amounts to 36 watts. Based on similar
lighting
levels a lighting installation with the conventional inductive ballast therefore
requires
at least 30% more energy than an identical lighting installation fitted with
Electronic
control gear.
C.E.L.M.A.: Energy Efficiency Index [EEI]:
CELMA the federation of National Manufacturers Associations for Luminaries
and electro technical components for luminaries has introduced the parameter of
Energy efficiency Index which serves as a basis for an objective evaluation of
the
efficiency of a ballast Lamp- system. The EEI measurements are based on
European Norms EN50 294 “ Measurement method of total input power, Lamp,
ballast, circuit.

MELCON electronic control gear units are designed developed and
manufactured
in accordance with the stringent quality control system of DIN ISO 9001
MELCON electronic control gear can detect when a fluorescent is reaching the
end of its normal operation and deactivate the lamp. Thus abnormal phenomena,
which can occur with conventional ballasts are prevented.
With MELCON electronic control gear in use time consuming mains switching
is no longer necessary as replaced lamps are automatically re-ignited.
