Product information

Description

The Osram HTM 70/230-240 is an electronic lighting transformer designed for mains voltages of 230–240 V. It offers a compact functional design (108 × 52 × 33 mm) and is available in turquoise and white. With protection class II and high efficiency, this transformer delivers low power loss and supports long lamp life through protective operation across the entire partial-load range.

Advantages

The HTM 70/230-240 provides very low power loss due to high efficiency and supports both leading-edge and trailing-edge dimming. Its compact dimensions and versions for space-critical installation (HTN for extremely compact applications) make it suitable where installation space is limited. The device includes strain relief compatible with different cable types (HTM) and maintains protective operation throughout the partial-load range to extend lamp lifetime.

Suitable for

  • Indoor low-voltage halogen and compatible lighting circuits requiring a 230–240 V input
  • Installations with limited space or recessed mounting where compact size is required
  • Dimmable lighting systems using leading-edge or trailing-edge dimmers
  • Projects needing class II protection and reliable partial-load operation

How to use

Install the transformer in accordance with applicable electrical standards and local regulations. Position the unit where its compact dimensions fit the available space and ensure the correct input connection to a 230–240 V supply. For cable routing, use the supplied strain relief suitable for different cable types (HTM). When dimming is required, connect compatible leading-edge or trailing-edge dimmers and verify correct dimming behaviour during commissioning. Ensure adequate ventilation and secure mounting to prevent strain on cables.

Usage recommendations

For reliable operation, use the HTM 70/230-240 within its specified input voltage range (230–240 V) and avoid overloading beyond its rated output. Select compatible dimmers and low-voltage lamps to benefit from low power loss and extended lamp life. Follow manufacturer installation instructions and local electrical codes.
