    Be interested in any feedback/experience using the Osram ET-Redback electronic transformers. They seem to be the preferred stocked electronic transformers up here and quite cheap by comparision to the Atco Possum.

    I have used the Possums in the past with very good reliability, before I made a switch to the Et-Redback thought I would ask what others have experienced.

    Thanks and regards,

    Fleetz

    Based on no positive comments on the Osram ET-Redback transformers I will go the Atco Possums at a few extra dollars per electronic transformers.

    Red-back trannies

    I have about 20 installed around the house. All about 3 years old. The first one failed today. I opened it up and a component that connnects direct to the 240v had obviously failed. Blackened and black soot sprayed on the case.

    I could not identify it. Not sure if it is a small coil, capacitor, or diode else I would replace it. Can anybody help with a circuit diagram and/or component list?

    Osram = no problem.

    I just had a product brochure come through on my email about the new improved red back, so thought I would share it with you, since you asked.
    I've used a lot of Osram product over the last 11years and had very few issues. Admittedly I've only used the redbacks 2 or 3 times, but the odd time there was an issue, Osram were excellent with replacement product.

    I certainly DO NOT advocate using MR16 or GU10 Led lamps in general, but there are many folk who do and in some instances, there is little other option, and in those cases I've used Osram and have been pleasantly surprised.

    "The new and improved REDBACK has arrived!
    The ET-REDBACK 40VA replaces the highly successful ET-REDBACK 60VA electronic transformer for halogen lamps."

    "Apart from being smaller and more compact in design, the REDBACK looks the same and retains all the great features of its predecessor, along with improved performance and reliability. Dimmable with both leading and trailing edge dimmers*, it is available as hard wired or pre-wired and features simple wiring for easy installation."
    " Compatible with C-Bus, Dynalite and HPM dimming systems*."

    "Why the reduction from 60VA to 40VA?

    — MEPS bans introduced in 2012 meant that MR16 halogen lamps >37W were no longer allowed to be sold into the Australian market. In the majority of cases, 40VA is ideal for most downlight applications. For higher wattage halogen loads, OSRAM also offers the HTM series of transformers available in 70VA, 105VA and 150VA.

    — Reducing the maximum capacity (60VA to 40VA) also means that the minimum load threshold can be lowered (20VA to 10VA), leading to improved compatibility and stability with lower loads as seen with LED retrofit lamps.

    Application areas

    — For use with all domestic halogen and LED** downlight applications

    * Dimming compatibility only guaranteed with halogen lamps. Dimming performance and compatibility cannot be guaranteed with LED lamps. When dimming LED lamps, always refer to the lamp manufacturer’s specifications and recommendations. Dimming behaviour may vary between different dimmer types. Independent tests are recommended to confirm the dimming performance before commencing a large scale installation to ensure acceptable performance.
    
    **Compatibility with LED lamps cannot be guaranteed. Always refer to the lamp manufacturer’s specification sheet for transformer compatibility and recommendations."

    hope that helps
    P.S. I'm an independent consultant, I do not work for Osram, but do like there stuff.
