Compatible TRP Drivers:

These are all compatible with this module. Choose the best driver for your application.

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 70ºC

ambient at nominal specifications. Heat sink is also required when

operated above specified drive currents.

Maximum Current

Max Current: 1440mA

Voltage at max current: 27V, Power at max current: 38.9W

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

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.

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.
