Description
The EFD-1K2SxxxDT series is a 1200W, constant-current, programmable LED driver that operates from 180528Vac input with excellent power factor. Created for many lighting applications including high mast, sports,
horticulture and aquaculture, it provides a dim-to-off mode with low standby power. 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, under voltage lock out,
input over voltage, output over voltage, short circuit, and over temperature.

Electromagnetic Immunity Requirements Applies To Lighting Equipment
Note: (1) This LED driver meets the EMI specifications above, but EMI performance of a luminaire that contains it
depends also on the other devices connected to the driver and on the fixture itself.
(2) To perform electric strength (hi-pot) testing, the “GDT ground disconnect” (nut and metal lock sheet) on the
driver end-cap should be removed temporarily to prevent the internal gas discharge tube from conducting (as
allowed by IEC 60598-1 Clause 10.2). After testing is completed, these items must be reinstalled to restore
line-to-earth surge protection and secure the end cap.

Notes
When R_NTC falls below R1, External
Thermal Protection is triggered, reducing
output current until R2 is reached.
When R_NTC is less than R2, output current
is reduced to the programmed “Protection
Current Floor.”
Over Temperature Protection
Decreases output current, returning to normal after over temperature is removed.
Short Circuit Protection
Auto Recovery. No damage will occur when any output is short circuited. The output
shall return to normal when the fault condition is removed.
Over Voltage Protection
Limits output voltage at no load and in case the normal voltage limit fails.

0-10V Dimming
The recommended implementation of the dimming control is provided below.
Implementation 1: DC Input
Notes:
1. The dimmer can also be replaced by an active 0-10V voltage source signal or passive components like
resistors and zener.
2. Do NOT connect Dim− to the output V− or V+, otherwise the driver will not work properly.
3. If 0-10V dimming is not used, Dim + should be open.
