Choosing whether to install AD10's or LD11's

?

Be careful when deciding whether to use AD10 or LD11 modules for your lights.

In our own installation we installed mostly AD10 modules, but later found we wished we'd installed LD11's. Although LD11's are physically bigger than AD10's, and therefore require extra room for installation, the added functionality is well worth it. Being able to dim and brighten the lights is a real bonus, as is the silent operation of the LD11.

AD10's contain a large relay which allows them to control high currents, whereas the LD11 contains a triac which allows the LD11 to dim/brighten and also to turn on and off silently.

Obviously you must never use a LD11 for controlling appliances as they will draw too much current and fuse the module. It is also inadvisable to dim any appliance as the transformer inside might not be able to cope with the voltage drop and blow up !!
