Description
Multispan AV-41CT Digital Ampere Meter – Reliable AC Current Monitoring
The Multispan AV-41CT is a compact single-phase AC digital ampere meter designed for monitoring electrical current in control panels, distribution panels, industrial machines and automation systems. It uses a current transformer (CT) input and provides a clear digital indication of the measured current. Multispan’s documentation specifies a selectable CT range up to 4000/5A and Class 0.5 accuracy for the AV-41CT. (Multispan)

⚙️ How AV-41CT Works
The AV-41CT is connected to the secondary of a Current Transformer (CT). The CT scales the high primary current to a standard secondary current, allowing the meter to display the corresponding current value.
High-Current Load → Current Transformer → AV-41CT → Digital Current Display
The CT ratio can be selected using the meter’s CT-selection function according to the manufacturer’s operating instructions. (Multispan)

Its compact 48 × 48 mm format makes it suitable where panel space is limited. (Multispan)
⭐ Why Choose a Digital CT Ampere Meter?
A digital panel ammeter makes current values easy to read directly from the control panel. Using a CT also allows the meter to monitor higher current circuits while keeping the meter input within its specified measurement range.
For accurate operation, the CT primary/secondary ratio must be correctly selected and wired according to the manufacturer’s instructions.
