One important but often misunderstood factor in LED lighting installations is the power supply needed to operate your lighting. There are different types of power supply available for LEDs, including dimmable and plug-style options.

This article guides you through everything you need to know about using plug-style LED power supplies—including how to choose the right device for your application.

Using plug-style LED power supplies

Plug-style LED power supplies are designed to convert mains AC power into the correct DC voltage for your LED strips, modules, or other low-voltage lighting. They act much like a transformer, ensuring your LEDs receive the right current without risk of damage from surges or undervoltage.

Benefits of plug-style power supplies

  • Protection: Plug-style power supplies offer protection against electrical surges and spikes. Quality units will sense anomalies and help prevent damage to your LED equipment.
  • Easy installation: Most plug-style supplies are “plug and play”—simply connect your LED strip or modules, then plug the supply into a standard wall socket.
  • Simple to replace: If a power supply fails, it’s usually a quick swap for a new one.
  • Immediate use: No complex wiring required—just plug in and go.

How to choose the right plug-style power supply for your LEDs

Aside from your needs and budget, there are several technical factors to consider when selecting a plug-style power supply:

  • Voltage: Always match the output voltage of the power supply to your LED product—12V for 12V strips/modules, 24V for 24V products, etc. See our expert guide on LED power supply voltage options.
  • Current/power draw: Calculate the total wattage your LEDs will use, then choose a supply rated at least 20% higher for safety and reliability.
  • Temperature and weather: If your installation is outdoors or exposed to moisture, check the IP rating. Most indoor plug-style PSUs are IP20; for outdoors, look for IP67 or higher.
  • Class II vs Class 2: Understand the difference: Class II supplies have reinforced insulation for extra safety, while Class 2 supplies limit output power to reduce shock risk.

Frequently asked questions

How do I choose the right power supply?
Add up the total wattage of your LEDs, ensure the voltage matches your products, and allow for some extra headroom. Consider the environment (indoor/outdoor) and check the IP rating.

What’s the difference between male and female DC adaptors?
Male DC adaptors (jacks) have a central pin; female sockets have a hole to accept the pin. Our plug-style PSUs come with 2.1mm male DC plugs. Find matching connectors and adaptors here.
