Why Choose the APM Shunt Meter
The APM Shunt Meter is an ammeter designed for measuring DC current in conjunction with an external shunt. It measures DC currents from 0 – 1,000mV with 0.1% accuracy. Alternative meters for specific applications include:
- APM Amp Meter: auto-detects AC or DC currents up to 5A with 1% accuracy
- APM CT Meter: measures AC currents from 0 – 10,000A with 0.5% accuracy
The unique display combines the instant readability of an analog meter with the precision and functionality of a digital meter. Get quick recognition and precise functionality for the easiest to use and easiest to read panel meter available.
Easy-to-Read Display Technology
The APM Shunt Meter’s display combines the best of both digital and analog amp meters, making it easy to read even in challenging conditions.
- Two Contrast Options: Order the positive display for bright sunlight, or the high-contrast negative display for indoors.
- Large Readout: Optimize readability and accuracy with four 12mm [0.47″] digits.
- Adjustable Brightness: Change the backlight brightness to accommodate changing conditions.
- Wide Viewing Angle: Operators can read the meter from a range of positions.
- 40-Segment Curved Bar Graph: Get an immediate visual indication of parameters.
User Configurable Ammeter
The APM Shunt Meter is highly configurable using the APM configuration software. The easy-to-use, free software allows you to tailor the meter to your specific needs.
- Color Changing Backlight: Configure color and intensity, with flashing or static alerts for specific conditions.
- Configurable Scale & Range: Adjust offset, gain, linear scale, and min/max range with 20-point non-linear scaling.
- 10 Independent Alarms: Set conditions and actions to meet your requirements.
- Messaging Area: Display custom messages and annunciators.
- 16 Pre-set Configurations: Use position switches on the back of the meter to select pre-set standard configurations without software.
- Digital Output Delays: Set delays from 0.5 to 120 seconds.
Remote Monitoring
Every APM comes with a free lifetime subscription to Trumeter Cloud so you can remotely monitor the status of your systems. Just add on our plug-and-play APM Gateway to get:
- Customizable alarm conditions and thresholds for notifications
- Unlimited email notifications, plus options to add instant text messages
- Exportable data stored securely in the Cloud
Output & Communications
The APM Shunt Meter comes standard with two outputs to communicate with other systems: 1 digital (open collector) or 1 analog (4-20mA). In certain circumstances we can customize the APM Shunt Meter with Modbus RTU for further communications.
