ABOUT US
B2A AC AC Current meter 5-50A
€68.80 Tax included

Description
The B2A AC is a simple open-loop AC ammeter capable of measuring currents from 0A to 5, 10, 20, 30, 50A. It connects to the monitoring system via the VT405 transceiver. For example B2A AC 10A is used for measuring AC current 0-10A. The VT405 converter transmits measured current data to the Vutlan monitoring device. This plug-and-play transceiver easily connects to any analog port of Vutlan monitoring devices.

Use cases
The low-cost, accurate VT490 sensor provides real-time monitoring and control of environmental factors.
- Electrical Panel Current Monitoring: Measures load current from Hall effect transducers installed on feeders and circuits, enabling remote supervision of power consumption and overload detection
- Industrial Equipment Monitoring: Supervises motors, pumps, compressors, and production machinery to detect operational changes and unexpected load variations.
- Overload Detection: Generates alarms when current exceeds predefined thresholds, helping prevent equipment damage and power interruptions.
Required Components

VT405 Current Tranceiver
