Product Details

HALOTRONIC Transformers

Electronic transformers for converting and lowering voltages for 12 V, very low-voltage halogen lights.
Operates on 230 → 240 V power supplies; 0.50 → 60 Hz.
Maximum admissible ambient temperature of 50 °C.
Able to work on all variable controllers, at the start or the end of phase.
Able to tap into the primary circuit to supply the other HTLs.
Designed for surface or flush-mounted devices, tubular lighting systems and domestic lighting.
For use with direct current and emergency lighting installations.
Reversible electronic safety protection against short-circuits, overheating and overloads.

Low Voltage Lighting Transformers

Dimming Methods (where applicable):
Leading Edge:
The control device is either a thyristor or triac which blocks power until they are switched on by the control signal. At that point the current flows almost instantaneously and continues to flow until the end of the half cycle of the mains waveform. When the signal reaches zero, the device turns off and no more current is passed until it is triggered again. Turning the power on and off in this manner averages out creating a constant intensity level and by altering the precise trigger point over a period of time the lamp can be dimmed.

Trailing Edge:
Since this method of dimming uses transistor technology it is not limited to just switching, therefore current can be controlled gradually. Transistors can be programmed to pass current at the start of each half cycle, and gradually switch off later. This will control the full amount of power reaching the lamp without the side effects of a step increase in current.
