5.6.2 Resistance to
Overvoltage up to
400V
Usually, electronic control gear work with input voltages between 220 V and
240 V in a standard three-phase installation.
If the contact of the neutral conductor is missing or faulty, this value can
rise – depending on the load distribution – up to a maximum value of
√
2 * 230 V = 400 V
The resistance to overvoltage of non-dimmable QTi is 300 V for the
duration of two hours. Depending on the load distribution in an installation
normally values between 280 V and 400 V are achieved. To integrate an
optical warning signal without additional stress of components
QUICKTRONIC
®
INTELLIGENT units shut down the lamps at voltages
greater than 290 V. At the input of the ECG the input voltage is measured
in an interval of ms and the lamp is automatically restarted once the voltage
drops below 290 V, thus avoiding to influence the lamp life.
5.6.3 Lamp-ECG-
Combination
5.6.3.1 Straight Fluorescent
types
Besides the combination of T5/∅16mm-fluorescent lamps of equal length
additional fluorescent lamps can be operated in combination with QTi. All
lamp combinations have an ENEC approval, which means that the
fluorescent lamps are operated without loss of lumens compared to single-
wattage types.
