2 Mounting the driver/controller

2.1 Realizing the right thermal conditions

LINEARdrive 180 can be operated without a heat sink, as its own heat generation always stays
within an acceptable temperature range.
Being the most powerful of its range, LINEARdrive 720 must be mounted onto a heat sink. To
ensure the best possible contact between the LINEARdrive 720 and the heat sink, LINEAR-
drive 720 features a dual heat spreader.
The general rule of thumb you can use when calculating a heat sink's required dissipating ca-
pabilities is that an eldoLED driver/controller adds 10% at the very most to the power consump-
tion of the connected LEDs. In other words, if the connected LEDs consume 90W, the driver/
controller will add a maximum of 9W: the heat sink will have to be able to deal with a total of
99W.
It is recommended to keep ambient temperature values between -20
°
+122 F). If the ambient temperature exceeds these limits and causes the LINEARdrive to heat
up above normal operating values, its built-in overheating protection will make it shut down.

2.2 Removing the cover

To remove the driver/controller's cover:
1. Take hold off the driver/controller as indicated by arrow 1 in Figure 2.1: "Removing the
cover".
2. Pull the cover off the base unit in the upward movement indicated by arrow 2.
