Electronic lighting transformer Osram HTM 70/230-240 — 70 W, 230–240 V, protective class II, compact size

Osram HTM 70/230-240 is an electronic lighting transformer for low-voltage halogen and compatible LED lamps with a rated output of 70 W. It accepts 230–240 V mains voltage and meets protective class II. The unit has a compact functional design (108 × 52 × 33 mm) in a turquoise/white housing and is intended for installations where space is limited and a Class II transformer is required.

Advantages

The transformer supports dimming on both leading-edge and trailing-edge dimmers and features very low power loss due to high efficiency. It includes strain relief suitable for different cable types and ensures protective operation across the entire partial-load range to extend lamp life. Its extremely compact form factor makes it suitable for highly space-critical installation conditions.

Suitable for

• Low-voltage halogen lighting circuits up to 70 W
• Compatible LED lamps requiring electronic transformers
• Residential and commercial recessed or cabinet installations with limited space
• Installations requiring protective class II devices

How to use

Install the Osram HTM 70/230-240 in accordance with local electrical regulations and wiring standards. Connect the mains supply (230–240 V) to the input terminals and the low-voltage lamp circuit to the output. Use appropriate strain relief for the cable type in use. Verify correct dimmer compatibility by testing with the intended dimmer and lamp combination before final installation.

Usage recommendations

Use with lamps and dimmers specified as compatible with electronic transformers; ensure the connected lamp load falls within the rated 70 W output and avoid continuous operation beyond the specified load range to maintain protective operation and lamp life.
