How many lamps can I run on a transformer?
Electronic transformers, both single and multi-output (ELT,EPC,ET,LP and PC ranges).
Between min. and max. rating of the transformer,
e.g. PC060/D rated at 20-60W, min load = 20W, max load = 60W (3x20W),
up to the maximum rating of the individual transformer.


How do I wire up my terminated electronic transformer?
All IBL terminated electronic transformers are clearly labeled with mains supply and secondary connection details. The termination covers are removed either by unscrewing the single clamp screw (ELT, PC), or by prising-off the cover (EPC) with the aid of a terminal screwdriver as described in the installation instruction leaflet.
Further information can be found in the IBL DATA SHEETS or INSTRUCTION LEAFLETS in the download section.


Can I join the terminals together on a multi output electronic transformer to get a single output?
Joining terminals together is not recommended, as it is possible that the individual terminal current rating will be exceeded. This could result in the terminal overheating.

What are the dimensions and weight of my electronic transformer?
Please refer to the product datasheet (available to download from the product page), or refer to the IBL catalogue.

What type of dimmer can I use with my IBL dimmable electronic transformers?
IBL dimmable electronic transformers are designed to work with either leading edge, or trailing edge phase control dimmers.

Why do IBL electronic transformers give no output drive until a lamp is connected?
IBL electronic transformers require a lamp to be connected to the output to enable the drive circuit. If a lamp is not connected, the transformer will shut down. This feature protects the transformer against damage resulting from driving into an open load, and conserves energy by shutting down the transformer in the event of lamp failure.

Why do I get strange voltage readings when I measure the output of my IBL electronic transformer?
The output from an IBL electronic transformer is at a high frequency, about 35kHz, modulated at 100Hz. If you use a ‘standard electrician’s multimeter’ to measure the output voltage you will get a reading that bears no relation to the actual output voltage. This is because the meter is not able to convert the complex waveform into an accurate rms voltage reading.
To be able to get an accurate measurement, a ‘true-rms’ meter should be used with a bandwidth of at least 50kHz.
