Are low voltage transformers the same as control transformers?

No, they are not the same. Low voltage transformers are electrical devices that convert high voltage electricity to low voltage electricity. Control transformers step down high voltage to a more manageable voltage that can power control devices. While they both help to reduce an overload of high voltage, low voltage transformers are for use in landscape lighting and other general lighting purposes. Control transformers, on the other hand, were created for control circuits.

How to test a low voltage transformer?

Before testing the transformer, disconnect the power source. Then, use a multimeter to measure the input voltage and verify if it matches the transformer’s rating. Next, check the output voltage at the secondary terminals to ensure it meets the specifications. Test both primary and secondary windings for open circuits.

Perform a load test by connecting a load and monitor the output voltage for stability under the operating conditions. Now, inspect for overheating, noises, or physical damage.
