Dimming

Dimming options and lamp voltage

Important! The lamp voltage rating must exactly match dimmer output voltage. Installing a
lamp with an incorrect voltage rating may damage the dimmer beyond repair and/or
destroy the lamp as soon as power is applied.
Three dimming options are available for the MAC TW1. Regardless of which option is used, the voltage
rating of the lamp must match the voltage supplied by the dimming device or system (see also Figure 4):
• A model with an internal multi-voltage IGBT dimmer is available. This dimmer is auto-sensing and accepts
power in the voltage ranges accepted by the fixture (100-120 V and 200-240 VAC nominal at 50/60 Hz)
and supplies the lamp with power at the voltage supplied to the fixture. If the internal multi-voltage dimmer
is used, the lamp voltage rating must match the voltage at the fixture's power input.
• A model with an internal 80 V dimmer is available. This dimmer is also available as an accessory but must
be installed by a qualified service technician. If an 80 V internal dimmer is used, the lamp must be rated
80 V regardless of the voltage at the fixture's power input.
• Power from an external dimming device or system can be supplied directly to the lamp in all models via a
Neutrik PowerCon
must match the external dimmer's output voltage regardless of the voltage at the fixture's power input.
We strongly recommend that you keep a record of the lamp voltage rating and internal dimmer type installed
and label these clearly on the fixture.
Do not apply power to the fixture or move the internal/external lamp power switch on the connections panel
unless you are certain that the lamp voltage rating is correct for the dimming system you are using or
switching to.
Damage caused by using a lamp with an incorrect voltage rating is not covered by the product warranty.
