Description
The ESM-1K2SxxxMx series is a 1200W, constant-current, programmable and IP66/IP67 rated LED driver that
operates from 249-528Vac input with excellent power factor. Created for many lighting applications including high
mast, sports, UV-LED, aquaculture and horticulture etc. It provides an auxiliary voltage and dim-to-off functionality
for powering low voltage, wireless controls. The dimming control supports 0-10V dimming as well as two-way
communication via Digital Dimming, a UART based communication protocol. The high efficiency of these drivers
and compact metal case enables them to run cooler, significantly improving reliability and extending product life.
To ensure trouble-free operation, protection is provided against input surge, input under voltage, input over voltage,
output over voltage, short circuit, and over temperature.
