PTB20W-0420-42-ZN ERP Constant Current LED Driver

The ERP Power PTB20W-0420-42-ZN is a programmable Class 2 constant-current LED driver designed for reliable performance in architectural and commercial lighting applications. Delivering adjustable output current from 250 to 420 mA with a factory default of 350 mA, this driver supports LED loads operating between 28 and 42 Vdc for precise lumen control and consistent light quality. Its wide 120–277 Vac input range makes it suitable for a variety of commercial installations, simplifying inventory and specification across multiple projects.

Engineered with Enhanced Tri-Mode dimming, the PTB20W-0420-42-ZN ensures smooth, flicker-free dimming across TRIAC, ELV, and 0–10 V systems, including dim-to-off functionality for modern lighting designs. The compact IP20-rated enclosure with mounting clips allows for easy integration into LED luminaires, while high power factor, low inrush current, and Class 2 compliance support energy efficiency, safety, and regulatory requirements in professional lighting environments.
