Description
The ESM-240SxxxLx series is a 240W, 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.

When the actual NTC resistance value is
lower than R2, the output current will stay at
