ERG driver boards employ a dc-dc boost circuit that supplies voltage to a constant-current driver and LED rail. The compact-sized boards come standard with input voltages of 12, 24, or 48 Vdc, in single, dual, or three-channel versions. The LED driver board with 48-Vdc input measures just 34 × 60 mm. Highly efficient thermal management gets the heat out of LED rails and the display assembly for higher reliability. Standard features include separate enable/disable and PWM high-ratio dimming controls.
