Matrix Railway LED Taillights/Marker Lights incorporate a low profile design and an advanced wide range power supply. The operating input voltage range of from 22Vdc to 95Vdc. This voltage range covers most of industry’s voltage standards such as 24 Vdc, 37.5 Vdc, & 74 Vdc +/- 20%.
The marker light circuitry designed with 6 redundant LED circuits so that in case of an LED failure, operation and maximum safety is maintained throughout entire car daily run.
The Marker Light’s regulators eliminate EMI/EMC emissions, and its input protection circuitry protects against Over/Under voltage, Over/Under current, reversed voltage, and fast transients. Matrix Railway Marker Light is provided with a 5 Year Warranty.
