ArcLamp System Installation Manual
ArcLamp Voltage Drop
Note:
The installation site must consider power requirements at the fixture and allow
for voltage drop with distance.
ArcLamp is a 180 mA, 24 VDC lamp that contains onboard voltage drop compensation
technology. However, correct operation 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. The table below lists the maximum distance between the ArcLamp driver and
ArcLamp based on using each driver at its maximum rated capacity. These distances will be
reduced when bridging driver output channels together (see
Bridge Output Channels on page 37
). Maximum distances depend on wire gauge. See recommended wire gauges at
Driver Installation on page 15
for wall-mount models and
Rack-Mount Driver Installation on
for rack-mount models. For your convenience, an interactive voltage drop calculator is
available at
