LED Driver Power Supply Buying Guide

The LED driver is the single most failure-prone component in any luminaire — and the most important one to get right in commercial specifications. Kingseng’s approach to driver selection ensures reliability across our entire range, but understanding the fundamentals helps B2B buyers make informed procurement decisions.

Driver Types Used in Kingseng Products

Constant Current Drivers: Standard in our KS-PL pendant series (KS-PL-001 to KS-PL-013) and KS-WS wall sconce series. Output current is regulated to ±3% accuracy, ensuring consistent light output across the installation.

Constant Voltage Drivers (12V/24V): Required for our KS-T8WH wiring harnesses (KS-T8WH-001 to 004) and linear strip applications. Our matching 24V drivers deliver 94% efficiency with overvoltage and short-circuit protection.

Isolated vs. Non-Isolated: Kingseng uses isolated drivers in all products destined for North American and European markets (UL/CE certified), providing full galvanic isolation for occupant safety.

Key Specs for Procurement

— Power Factor: > 0.9 for all Kingseng drivers (compliance with EN 61000-3-2)

— Efficiency: > 90% across the load range

— Lifetime: 50,000 hours at Tc = 75°C

— Protections: Overvoltage (OVP), overcurrent (OCP), short-circuit (SCP), and thermal shutdown

Our T8 Retro Brackets include integrated driver mounting for clean, code-compliant fluorescent-to-LED conversions. For dimming applications, our KS-LT-22W track light uses a 0–10V dimmable driver with smooth fade-to-black down to 1%.
