What is an LED power supply?

An LED power supply (also called an LED driver) converts high-voltage AC mains or DC bus voltage into precise constant voltage or constant current DC power required to run LED arrays safely and efficiently, protecting components against power spikes and thermal runaway.

How do I choose between Constant Voltage and Constant Current LED drivers?

Constant Voltage drivers (e.g., 12VDC, 24VDC, 48VDC) are designed for LED fixtures with built-in current-limiting resistors or internal regulators, such as strip lights. Constant Current drivers directly supply a fixed amperage to raw LED arrays, preventing thermal degradation and ensuring uniform luminosity.

What ingress protection (IP) ratings are available for harsh environment lighting?

Wall Industries supplies LED power modules ranging from open-frame IP20 units for indoor enclosures to fully potted IP67-rated waterproof drivers suitable for outdoor, damp, washdown, and rugged industrial applications.

What is the difference between UL Class 1 and UL Class 2 LED drivers?

UL Class 2 drivers comply with UL1310, outputting safe power levels (<60VDC / <100W) that reduce fire and shock risks without requiring extensive circuit insulation. UL Class 1 drivers offer higher output power for high-bay lighting arrays but require secondary safety measures in fixture design.

Selection & Application Guide

How to Select an Industrial LED Power Supply

Key technical parameters engineering teams must evaluate when specifying LED drivers for OEM machinery, commercial buildings, and harsh environment installations.

1. Constant Voltage vs. Constant Current

Matching the driver topology to your LED payload is crucial for system longevity:

Constant Voltage (CV): Supplies a fixed DC voltage (e.g., 12V, 24V, 48V). Essential for LED strip lights and fixtures with integrated current-limiting resistors.
Constant Current (CC): Delivers a precise amperage output while adjusting system voltage. Recommended for high-power LED chips to prevent thermal runaway and light output variations.

2. Power Factor & Operating Efficiency

High-efficiency LED power supplies minimize energy waste as heat and lower operating cost:

Select drivers with an efficiency rating of 85% or higher to reduce internal power dissipation.
Ensure high Power Factor Correction (PFC > 0.95) to meet municipal power grid quality standards and industrial facility codes.

3. Environmental Ingress Protection (IP Ratings)

Match mechanical packaging to environmental hazard levels:

IP20 / Open Frame: Suitable for indoor control cabinets and dry luminaire housings.
IP65 / IP67 Fully Potted: Sealed against dust, moisture, high humidity, and temporary liquid immersion, ensuring reliable operation in wet or washdown areas.

4. Safety Approvals: UL Class 1 vs. UL Class 2

Understanding regulatory requirements simplifies final product certification:

UL Class 2 (UL1310): Limits output to <60 VDC and <100W. Reduces shock and fire hazard risks, allowing simpler luminaire wiring without heavy isolation shielding.
UL Class 1: Supports higher power density and output voltages for demanding industrial high-bay applications, requiring safety grounding and isolation inside the light fixture.

Frequently Asked Questions

LED Power Supply Engineering FAQ

An LED power supply (also known as an LED driver) regulates electrical power supplied to LED arrays. Because LEDs run on direct current (DC) at low voltages, the power supply safely converts line voltage alternating current (AC) into stabilized DC voltage or DC current to preserve light efficiency and operational lifespan.

LED output luminosity is directly tied to supply current. Fluctuations in input AC line voltage can lead to rapid current changes, causing LED flicker, overheating, or premature failure. Constant current LED drivers continuously adjust output voltage to maintain a fixed amperage, protecting LEDs against electrical stress.

Wall Industries offers LED power designs compatible with common dimming protocols, including Pulse-Width Modulation (PWM) and TRIAC AC phase-cut dimming. Depending on the series, 0-10V analog and resistance dimming options are also available.

Yes. We frequently provide modified-standard solutions — adjusting output voltage trim, custom wire harness connectors, specialized potting compounds, thermal baseplates, or custom mechanical brackets — allowing OEM clients to shorten development timelines while securing exact physical and electrical specs.
