GlacialPower’s RS series of constant current and constant voltage drivers
|
-
The output voltage of the two LED lights ranges from 12V DC to 57V DC. GP-RS45P delivers up to 48W, and
-
GP-RS60P up to 60W of power to the LED
-
Available with a 3-in-1 dimming (1-10V/PWM/resistor) function
-
Robust IP67-approved plastic housing protects the drivers from possible dust or water damage such as rusting
-
Double insulated wiring design ensures that if the wire is externally pulled, the strain relief bushing to the circuit board will not be exposed, preventing possible electricity leakage
-
Universal AC input 90 to 305V AC

ON Semiconductor’s NCL3008x series
|
-
Uses information on the primary side to precisely regulate the current in the secondary side, providing constant current for fly-back and non-isolated buck-boost topologies
-
The series provides best-in-class primary-side current regulation < ± 1% (typ), thus simplifying LED selection
-
Supports wide forward voltage (Vf), simplifying design and reducing engineering cost
-
Features high efficiency quasi-resonance switching with low EMI generation
-
User-controlled thermal current fold-back protecting LEDs from improper usage
