4.7” Round Std. DC

LED Light Engine Module

Step Dimming:

This Light Engine can be step-dimmed, with a recommended

TRP dimmable driver and SD series step-dimming module.

See the SD2 or SD3 data sheet for wiring information.

Maximum Run Lengths

The max number of boards wired in a chain

(series) is limited by the

max current rating of the first board wired to the driver. The sum of the

board currents, in the chain, funnels through the first board. Multiple

chains can connect directly to the power supply in parallel. See table

for max chain length.

Mounting Notes

The LED assembly is supplied with mounting holes, per the dimensional

drawing. It is important to mount the board in such a way as to maintain

the Tc point below the max. The steady state thermals in application

will dictate if the board needs to be mounted directly to metallic housing

and/or include a thermal pad. For example fully enclosed recessed

fixture will require better thermal mounting than an open air pendant.

Thermal Application Notes

This board requires additional heat sinking to run above 45ºC

ambient at nominal specifications. Heat sink is also required when

operated above specified drive currents.

Maximum Current

Max Current: 900mA

Voltage at max current: 40V, Power at max current: 36W

The total maximum current reflects the LED maximum forward current

only, without considering thermal needs. Driving the LEDs this hard will

likely violate their thermal limits, depending on the application.

Tc point

must remain at or below the max temperature, or the warranty will

be voided. Temperature is directly correlated to LED current.

Static Sensitive Device

Handle only at static-safe work stations.

Packaging

50 per box standard.

Series/Parallel Configurations

Parallel: The positive and negative of one board is connected

to the respective positive and negative of the next.

Current adds, so the supply must be 2x the current

for 2 boards.

Series: The negative of one board is connected to the

positive of the next. Voltage adds, so the supply

must be 2x the voltage for 2 boards.
