Transformer For Tension Wire Systems - Polished Chrome

This drum transformer for tension wire systems is available in two outputs 100 and 200va. Both sizes are supplied in a polished chrome housing.

To find the right size transformer for your needs add up the wattage of the lamps and ensure the wattage of the transformer matches or is higher than your total i.e. 5 x 35w lamps would need a 200va transformer.

That said you should aim to use at least 80% of the capacity of the transformer i.e. 80w on a 100va, 160w on a 200va for optimum performance.

Dimensions and details:

100va (100 watts) 125mm diameter and 95mm deep

200va (200 watts) 155 mm in diameter and 115mm deep

On some lighting circuits, a Type C MCB may have to be used to avoid tripping because of the higher current associated with this type of transformer - this only cost a few pounds. While toroidal transformers are dimmable they often have an issue with harmonics (a buzzing noise) that may be present.

IMPORTANT NOTE: when installing the cable into the 12v output ensure they have a good connection. Cables that are not sufficiently secured create resistive connections which may cause excessive heating or fire. We recommend tinning the cable with solder for a good connection. Periodic checking of the tightness of any connections is recommended.
