LED driver is a power transformer, which is responsible for regulating and supplying the constant and uninterrupted DC current for the variable needs of LEDs.
From client’s after-sales survey, the defective rate of our led driver is less than 0.2% after 3 year usage.
The outdoor IP65 LED power supply for circuit board integration is a premium, high-density power conversion component engineered specifically for rugged outdoor luminaires, industrial smart nodes, and architectural LED systems. Fully encapsulated in a resilient, silicone-potted IP65 weatherproof enclosure, this board-level power module delivers exceptional thermal dissipation efficiency and absolute protection against dust ingress, heavy downpours, and severe localized humidity fluctuations.
Resilient CC/CV Power Topologies: Engineered with robust isolated flyback or resonant switching topologies, utilizing premium solid capacitors and industrial-grade MOSFETs to maintain flawless, ultra-stable voltage regulation and line efficiency (up to 91%).
Advanced Active PFC & Power Quality: Integrated with advanced active Power Factor Correction (PFC) control circuitry, achieving a Power Factor (PF) > 0.95 and Total Harmonic Distortion (THD) < 12%, ensuring strict compliance with global power grid interference and harmonics standards.
Ruggedized Surge & Circuit Protection: Equipped with an autonomous safety suite, including over-voltage protection (OVP), short-circuit protection (SCP), over-temperature thermal throttling (OTP), and robust 4kV/6kV surge suppression to withstand volatile outdoor power grid spikes and lightning transients.
Optimized EMC/EMI Compliance: Designed with multi-stage electromagnetic interference (EMI) filtering to prevent radio frequency noise generation, guaranteeing flawless co-existence with localized wireless IoT control nodes, smart meters, or radar sensors on the same circuit network.
