As with all low-voltage products, ArcLamp installations must take into account voltage drop over distance.
Not to worry - the handy ArcLamp Volt Drop Calculator can help you design your system. Select the ArcLamp driver being used, the total amount of ArcLamps that will be connected to each of the 4 outputs of the driver, and the length
and gauge of cable you plan to use. The calculator will determine if your proposed configuration meets the minimum requirements for the lamp to operate.
ArcLamp driver outputs may also be ‘bridged’ together using the provided bridging kits to increase the lamp capacity of each circuit. Here is an example of how bridging may be implemented using a 350W driver:
1 x ArcLamp 350W Driver has the ability to support up to 60 of the 4.4W ArcLamp.
Option 1 – Connect 15 ArcLamps to each of the 4 outputs - total of 60 lamps on 4 circuits
Option 2 – Connect 30 ArcLamps to 2 bridged pairs of outputs for a total of 60 lamps on 2 circuits
Option 3 – Connect 60 ArcLamps to 1 bridged quad of outputs for a total of 60 lamps on 1 circuit
To determine acceptable cable sizes for ArcLamp Driver applications, please review the
ArcLamp System Installation Manual. For F-Drive applications, find accepted cable sizes in the
R12 Installation Manual.
The ArcLamp Volt Drop Calculator tool is intended to be used for guidance only. Actual results vary depending on external factors, such as cable integrity.
