High Output Wide Range LED Power Module
DATA SHEET Page 6 of 9
External On/Off Control
Where a manual on/off control is desired, the potentiometer in Figure 14 may be replaced by a
pushbutton or toggle switch. The output current will be zero and the input current will drop to the
quiescent level when the switch is closed. Figures 16 and 17 show external dimming control combined
with on/off control.
Thermal Management
The FlexBlock can run many LED load configurations with no additional heat sinking in an ambient of
25 ° C. In situations with elevated ambient temperatures, such as those that might be experienced inside
an enclosed fixture, additional heat sinking may be required. If the temperature of the driver (as
measured at the T marking on the label) exceeds 60 ° C, additional heat sinking is recommended. If the
temperature of the driver exceeds 80 ° C, additional heat sinking is required.
The best surface for removing heat form the FlexBlock is the back side (opposite the labeled side). The
module can be attached to a heat sink with thermal grease and a mounting bracket that presses the unit
firmly against the heat sink, or with double-sided tape that provides both the thermal path and
mechanical mounting. When using tape (such as 3M F9469PC, a Very High Bond (VHB) tape suitable for
permanent mounting), using a thinner variety (0.005” thick or less) will aid in getting the heat through
the tape and to the heat sink. Care should be taken when positioning the FlexBlock module with VHB
tape as the high bond strength makes removing or repositioning the module very difficult.
If the FlexBlock becomes too hot during use, it will reduce the output current to limit the power
dissipation. If the temperature continues to rise, the driver will turn off until the temperature drops to a
safe level.
Connections
In all cases, the LEDs being driven should be located as close to the FlexBlock LED output as possible.
18AWG wire should be adequate for most wiring, but a heavier gauge should be considered when
long leads are required.
The power input wires should also be kept short. Where the power source is located several feet from the
unit, a 100μF or larger, 50V capacitor may be required across the input terminals as shown in Figure 20.
