How do I know what size LED transformer I need?
To decide how much power your LED strip driver needs, multiply the length of LED tape you have (in metres) by the wattage per metre. For example… This means you will need an LED transformer that can supply 35 watts (at least).
Do you need a special transformer for LED lights?
All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally.
How many amps do I need for a relay?
Once in motion, the the motor may consume no more than 5 amps. When driving these types of loads, choose a relay that exceeds the initial requirement of the motor. In this case, a 20-30 Amp relay should be used for best relay life. Induction Suppression Capacitors Controlling inductive loads requires the use of induction suppression capacitors.
What do you need to know about a relay?
So here is an overview of what a relay is, why you likely need it, and how to wire it up. What is a Relay? A relay is an electrical switch. It allows a low current “switch” circuit to control the electricity flow of a high-current circuit load, like your LED Light bar for example.
How to choose a power supply for a led project?
When selecting a power supply for your LED project it is important to know where it needs to fit or be installed. If you wish to put it inside the product you are making, it has to be small enough to fit in the space provided. If it is outside the application, it should have a way to mount close by.
How to determine the limit of a relay?
Volts x Amps = Watts – Never Exceed Watts! An easy way to determine the limit of a relay is to multiply the rated Volts times the rated Amps. Every relay will have two ratings: AC and DC. You should determine the AC watts and the DC watts, and never exceed these ratings.
