ELD3-2-M is a CoolLED 500 mA Maintained Emergency LED Driver (240 V).

The ELD family of emergency, maintained and non-maintained LED drivers from Harvard Engineering offer simple, cost effective solutions for locations requiring reliable, low-power lighting in the event of mains failure. A single compact unit incorporates intelligent control of both battery charging and constant current drive to the LED. A separate output is available to power a small indicator LED giving the status of battery charge.

High efficiency operation permits use of a small, 2-cell battery while still providing 3 hours emergency operation.

Additionally, the -M version of the product features a switched-live input to enable use of the LED for general illumination in addition to emergency operation.
