What is a Low Voltage Transformer?

Let’s explain what a low voltage transformer is all about, you need to understand the difference between a low voltage transformer and a line transformer.

The line voltage transformer has an average of 120 to 220 volts, whereas the former functions below the 120 voltage level.

Because of this, specific rings lights require a low voltage transformer of 12 volts.

Nevertheless, it depends on the performance, overall construction, and power rating to determine how well a particular low voltage transformer performs.

There are usually two types of low voltage transformers – mechanical and electrical.

Mechanical transformers comprise different windings, which provide several types of automatic loss. Due to this feature, it reduces the transformer efficiency.

Alternatively, the electric transformer doesn’t contain any magnetic loss, thereby providing less electricity loss within the system.

What is The Maximum Life Span of a Transformer?

In most situations, the transformer works efficiently for four to five years without experiencing any significant damage.

Besides these, there are several reasons why your transformer might develop faults; you can learn more on this video

Simple maintenance tips to try

To improve the lifespan of your transformer, you have a role to play. You can try these maintenance tips for your low voltage transformer.

Besides the maintenance tips offered in the manual, these can come in handy to improve the efficiency and performance of your transformer.

  • Don’t connect the transformer with any faulty electric line
  • Don’t allow the transformer to fall from your hand
  • Never use the transformers in a water connection, especially if it doesn’t offer submersible quality
  • Don’t take it close to fire or use it during a thunderstorm
  • After use, ensure you store the transformer in the packet
  • Ensure you keep the transformer from direct sunlight and dust
  • Don’t place any heavy items on the transformer
  • After usage, avoid keeping it in an open space
  • Ensure you troubleshoot the device frequently to prolong its lifespan

Malibu Low Voltage Transformer Timer Not Working?

Although the Malibu low voltage transformer is touted as the best low voltage transformer doesn’t mean it always works. In some cases, you might experience that the timer is not working.

Once you experience a switch failure, the first culprit is the timer. Timer problem is a common problem that occurs in most transformers, and here is where you have to utilize your warranty if you have any.

Therefore, before you think of installing a low voltage transformer, you should do the following.

  • Ensure you use a power surge protector to safeguard it
  • Know the power pack wattage that matches with the wattage of the installed light bulbs
  • Avoid using a cheap timer and a low-quality power pack for your transformer

For instance, if you are using 15 bulbs with each having 20 watts, the ideal power pack is 300 watts. (15 x 20 watt bulbs = 33-watt power pack).

However, if you use a 500 watts power pack for the same number of bulbs, it will be the wrong wattage. For example, using a 500 watt for 15 bulbs with each providing 20 watts.

Therefore, a mismatch of power wattage will burn your power pack and bulbs. Nevertheless, if your timer doesn’t work, the clock motor is leaked, or the motor gear might be stripped.

If it still doesn’t work after doing these, you should reset the timer and restart the system.

Peradventure, it still didn’t work, then you can consider throwing the transformer away and buying a new one. Instead of repairing the transformer, it is advisable to purchase a new one.
