The ESM-1K2TxxxMx series is a 1200W, 3-channel, constant-current, programmable and IP66/IP67 rated LED driver that operates from 249-528Vac input with excellent power factor. This driver can support 3-channel luminaires to adjust current separately. 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 troublefree operation, protection is provided against input surge, input under voltage, input over voltage, output over voltage, short circuit, and over temperature.
