The current drawn by large numbers of ArcLamps is less than the calculated ideal, which
allows more ArcLamps to be driven by a single bridged channel than you might expect from
calculations.
Note:
All output channels have on-board overload protection. See
Note:
The installation site must consider power requirements at the fixture and allow
for voltage drop with distance. See
.
Voltage Drop
Correct operation of an ArcLamp requires a minimum of 21 VDC provided by the ArcLamp Driver
at the ArcLamp. Voltage drop calculations vary by project and are based on the type, length,
and gauge of wire used between the ArcLamp Driver and ArcLamp. Contact a qualified
electrician or ETC technical services for further information.
The ArcLamp Driver must be installed within a maximum distance of the fixture with ArcLamps
installed. Maximum distances will be reduced when bridging driver output channels together
and are dependent on wire gauge. See recommended wire gauges at
for wall-mount models and
Rack-Mount Driver Installation on page 25
for
rack-mount models. For your convenience, an interactive voltage drop calculator is available at
.
