ROTARY DIMMER 500 VA AND 1200 VA
W FUNCTION
Dimmer operated by a rotary knob for the power control of all standard types of illuminations, such as e.g. incandescent lamps,
high-voltage and low-voltage halogen lamps with electric or conventional transformers.
The these resistive-inductive loads or resistive-capacitive loads the dimmer can work in a normal or reverse phase control mode. If
the operating mode has been set incorrectly, or if a short-circuit occurs, the dimmer will automatically disconnect the load. In
addition, the LT 500 M and the LT 1200 M are equipped with thermal overload protection, electronic short-circuit cut-out, overvoltage protection and a soft-start function.
The device is also provided with electronic half-wave balancing and idle monitoring. This ensures the prevention of magnetic bias
when conventional mains transformers are connected and of overvoltages when idling.

W TECHNICAL DATA – Continued
Conventional transformers for LV halogen lamps should be loaded least 20%. Too high an inductivity will result in the
dimmer´being switched off (idle detection). It is imperative tu use only trasformers ap¬proved by the manufacturer für phase angle
control (i. e. dimmer control at on).
a)
In the case of LV halogen lamps the transformer´s own power consumption has to be added to the lamp´s wattage when determining the total dissipated energy. With a matched transformer this may be assumed to be approx 10% of the lamp´s wattage.
b)
The dimming capacity is dependent upon the ambient temperature and applies to the specified range. Always allow for sufficient
ventilation in the distribution board. If serveral dimmers are mounted next to each other in the distribution board and also subject
to high loads, a ventilation space of approx 10 mm is recommended.
c)
d)
Observe the manufacturer´s specifications.
