High-Efficiency LED Drivers from ERG
LED drivers for large-format industrial displays.
Endicott, NY — Display power supply specialist Endicott Research Group (ERG) has introduced its Large Display Solutions: low-cost, high-efficiency LED drivers and rails specifically designed for LCDs in the 19 to 27-in. (483 to 686mm) diagonal range. Used in test and measurement, control, outdoor signage, gaming, medical and other applications requiring a larger display with high reliability, these LED driver modules power multiple LED strings and offer economically priced power solutions.

The new series includes the SFDZ, SFDQ and SFDT driver modules. All are available as standard products with wide input voltage design, small form factors, wide range dimming, and full brightness and enable control. They are plug-and-play compatible with most OEM LCD panels and are designed, manufactured and supported in the USA, with a one-year warranty.

The SFDZ Series driver provides high efficiency power (max. current 180mA per string) to LED backlights used in LCDs up to 24-in. (610mm) diagonal. It measures 1.35 x 5-in. (34.3 x 127mm), is less than 12mm high, and includes open/short circuit protection, over voltage protection, under voltage lockout and an adaptive string voltage, with onboard and external PWM dimming (0-5 V).

It provides total output power of 40 Watts (20W per side), powers up to 8 LED strings (4 per side) and is suitable for displays with dual light bars. The SFDQ Series driver provides power (max. current 140mA per string) to LED backlights used in LCDs up to 27-in. diagonal, with a maximum string voltage of 70V — the highest in the ERG LED Driver family — with external PWM dimming to 500:1 and onboard PWM dimming to 255:1. It measures 1.5 x 5-in. (34.3 x 127mm), and is less than 14mm high.

The driver provides total output power of 30 Watts and powers up to 4 LED strings.

The SFDT Series driver is capable of driving up to 12 discrete LED strings (6 per side) with a typical input voltage of 12V. It provides an onboard and external PWM dimming ratio of 255:1 and is compatible with several OEM LED backlit panels up to 27-in. diagonal.
