Description
The ESM-320SxxxMx series is a 320W, constant-current, programmable and IP66/IP67 rated LED driver that
operates from 249-528Vac input with excellent power factor. Created for smart lighting application, this family
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.
