LTF LED 60watt no load electronic AC driver transformer 24VAC ELV 0-10 dimmable 277volt input TE60WA24LEDB15

No-load electronic transformers can only be bench tested with devices capable of measuring at higher frequencies such as a Fluke 289 or better voltage meter. No-load can be measured this way with or without a load on the device. The reason for this is a lower end meter standard electricians field meter would measure voltage that are DC or < 50-60 Hz only and not this transformer.

Measurements done with a field voltage meter will give an incorrect reading or no reading at all. Please be aware of this when testing the transformer. The no-load is designed for both LED Loads, and halogen / Incandescent bulbs.

However, for standard halogen lighting loads a no-load transformer is not necessary. Total lighting supply offers a video on testing standard transformers. Request the video and we will send it to you.

No-Load transformers can be full loaded to the load specifications. However we cannot guarantee full load performance if your circuit is not engineered correctly for lighting loads, lamp type or wire gauge and length. Proper project engineering is required or downgrading the load on the transformer may be a option.

Example: With a 300watt transformer, one single run at 300watts may required a #10 gauge wire depending on the distance.
Low voltage wire when used on some loads have voltage loss based on load type, wire size and distance from the transformer. Splitting the load when available may be a good option as the amperage at full load is very high.
