Description
The ESM-320SxxxLx series is a 320W, constant-current, NFC programmable and IP66/IP67 rated LED driver
that operates from 249-528Vac input with excellent power factor. Created for smart lighting and health
monitoring applications, this family provides integrated AC power monitoring with an auxiliary voltage and dimto-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 that complies with
T/CSA-051. 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.

0-10V Dimming
The recommended implementation of the dimming control is provided below.
Implementation 1: Positive logic
Implementation 2: Negative logic
Notes:
1. Do NOT connect Dim− to the output V− or V+, otherwise the driver will not work properly.
2. The dimmer can also be replaced by an active 0-10V voltage source signal or passive components like
zener.
3. When 0-10V negative logic dimming mode and Dim+ is open, the driver will dim to off and be standby.
