OSRAM HALOTRONIC COMPACT Transformers

If your project involves the space-critical installation or different cable types, consider a HALOTRONIC COMPACT transformer. The HTN version is extremely compact and ideal for use where space is tight, while the HTM has strain relief suitable for different cable types. They are dimmable on the leading edge (without HTN) and trailing edge, very energy-efficient and have electrical isolation between the primary and secondary sides. HALOTRONIC COMPACT protects from short-circuit, overtemperature and overload (electronically reversible), and is ideal where you wish to install accent and/or effect lighting, to light objects and for surface-mounted/recessed furniture luminaires. Other applications include living rooms, event and conference rooms, shop lighting and restaurant lighting. High levels of efficacy mean that HALOTRONIC COMPACT loses little power, and its protective operation throughout the partial-load range promotes lamp life.

The OSRAM HALOTRONIC COMPACT Transformers are available in two power rating options to choose from:
• HALOTRONIC HTM 70W/230…240 - 281-8128
• HALOTRONIC HTM 105W/230…240 - 281-8134

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.
