5.1.2 MOSFET Dimmer Power Supply
The MOSFET dimmer is specifically designed to dim capacitive loads such as dimmable fluorescent
lamps and electronic ballast. Secondarily, it can also dim resistive loads such as incandescent, halogen,
and dimmable LEDs. The MOSFET dimmer is designed to dim 100–120VAC up to 350W.

and dimmable LEDs. The MOSFET dimmer is designed to dim 100–120VAC up to 350W.
The MOSFET Actuator also provides a class-2, 12VDC output used to power the MODEVA logic and touch
user interface and to provide connection and power for a wired S5-bus IRAS network.

5.2 Load Assembly Dimming
With the MODEVA product offering, INNCOM presents a “lighting control system in a box” that provides a
multifaceted range of modular and component level flexibility competitors cannot offer. Because of this,
INNCOM’s lighting control hardware quality must be on par with or exceed the competitions’. To achieve the
highest level of smooth dimming operation with both the MOSFET and TRIAC dimmers, a clean power line must
be available for the Load Assembly actuators. Corrupt zero crossing information will affect turn-on points and
turn-on time of the TRIAC and MOSFET dimmers, which ultimately affects dimming quality. Zero crossing
information and accurate line frequencies are a problem for dimming products because they are more sensitive to
line voltage problems. AC line evaluation to ascertain that it meets INNCOM’s minimum technical requirements
for dimming light loads is essential.
