The DP90S ThruPower module gives you the ability to add new lighting fixtures - incandescents, LEDs, moving lights and more - without worrying about circuitry. It has three output options - dimming, switching, or direct power - to control any lighting load. There is virtually no minimum load for the DP90S module, so even a single LED or fluorescent fixture can be dimmed. The DP90S module is plug-in compatible with all standard DP90 modules, so a single circuit or entire existing FDX system can be upgraded to receive the latest future proofing benefits. A plug-in upgrade kit for existing systems also allows processor upgrades to CEM3, so the same smooth fades and remote system management found in FDX3000 can be brought into FDX systems of any age.
