MEAN WELL LP Family: LPC, LPV, LPH & LPHC Series LED Drivers
Series Overview
The LP family (LPC, LPV, LPH, and LPHC) represents MEAN WELL’s specialized plastic-encapsulated LED drivers. They are engineered to provide robust, waterproof performance at an economical price point, making them the industry standard for high-volume signage, architectural, and decorative lighting projects.
- LPV Series (Standard CV): Standard Constant Voltage power supplies, ideal for traditional 12V/24V LED strips and modules.
- LPC Series (Standard CC): Standard Constant Current power supplies, ensuring stable, flicker-free output for direct-drive LED chips.
- LPH Series (Compact CV): Slim/Compact Constant Voltage power supplies, optimized for narrow light channels and space-constrained areas.
- LPHC Series (Compact CC): Slim/Compact Constant Current power supplies, designed for compact fixtures requiring direct mA driving.
Key Features
- IP67 Waterproof Rating: Fully potted with thermal-conductive silicone, providing complete protection against dust and water immersion. Perfect for damp, wet, or outdoor locations.
- Class II Design: No earth pin required (double insulated), significantly simplifying installation and reducing wiring complexity in light boxes and fixtures.
- Dual Driving Modes Available: Flexible design choices with dedicated series for Constant Voltage (CV) and Constant Current (CC) requirements.
- Fanless & Maintenance-Free: Completely silent operation utilizing passive free air convection cooling.
- Rugged Reliability: Built-in short circuit, over-voltage, and over-temperature protections. Designed to withstand a 300VAC input surge for up to 5 seconds.

Application & Selection Guide
Choose the correct LP series based on your LED load requirements (Voltage vs. Current) and installation space:
| LED Load Type | Standard Size | Compact / Slim Size |
|---|---|---|
|
Needs Constant Voltage (CV) (e.g., LED strips & modules with internal resistors) |
LPV Series | LPH Series |
|
Needs Constant Current (CC) (e.g., Bare LED chips, high-power COBs directly driven) |
LPC Series | LPHC Series |
Design & Installation Tips:
1. Thermal Management: Because these units are fully potted for IP67 protection, they efficiently conduct heat to the case. Always mount the unit on a thermally conductive surface (like a metal chassis or beam) to maximize lifespan in high-heat environments.
2. Voltage Matching (CC Models): When using Constant Current models (LPC/LPHC), ensure the total forward voltage of your LED string falls strictly within the DC voltage range specified on the datasheet.
