Current Loop 1 & 2
AVTECH
AVTECH’s Current Loop
monitors the electrical current flowing through a single-phase
powered cable. It outputs a signal of 0 to 5 VDC, which your built-in or external Room Alert
Analog Sensor then converts into an amperage (A) reading. By
pairing a Current Loop with your Room Alert, you can easily
determine the power consumption of an electrical appliance,
device or facility.
Current Loop Package Contents
•
One (1) Current Loop
•
Two (2) #8 x ¾" TEK mounting screws
•
One (1) 25' speaker wire
Select An Input Range
Your Current Loop arrives with its jumper set on the largest input amperage range: 0 to 50 A
on Current Loop 1, and 0 to 250 A on Current Loop 2. Select the High, Middle or Low range
to match the power draw of the appliance / device being monitored for the most accurate
readings.

To change the setting, pull the jumper up to detach it from the “H” pins; then push it back
down onto the “M” or “L” pins.
Install Your Current Loop
Do not use this sensor in hazardous (classified) locations or life safety applications.
The Current Loop has a split core which opens to wrap around a single insulated conductor
running into an electrical box or to an appliance / device.
Consult with a qualified electrician before you begin.
Disconnect power to the equipment and cable before you begin.
Do not insert an exposed wire into the Current Loop.
Step 1: Mount your Current Loop.
Mount the base of the Current Loop on a surface using the included self-drilling mounting
