Amp Meter

The APM Amp Meter is a digital panel amp meter that provides a more effective way of monitoring, measuring and displaying current. It measures up to 5A directly, or up to 10,000A in conjunction with a current transformer.

APM Ammeter Digital Panel Meter
The APM amp meter has been specifically designed for panel mounting and is ideal for a range of applications. Its unique LCD display combines the advantages of traditional moving coil meters with the accuracy and features of the leading digital panel amp meters.


Programmable digital panel amp meter

With a programmable scale, both minimum and maximum values on the bar graph can be configured and the ammeter customised as required. The amp meter’s set points and alarms can be programmed using the free to download and easy-to-use configurator software. The LCD display can be set to flash, change colour, change message or a combination of all three to alert the user when a critical point has been reached. Custom alarms can be set to trip when values exceed, are lower than, between or outside the set point.

Direct Current Measurement

The APM ammeter achieves an accuracy of 1% or better across the input range for precise control where accurate measurement is paramount. It has a direct input for measuring AC and DC currents up to 5A.


Current Measurement with a CT

The amp panel meter can be used in conjunction with a CT to measure AC current up to 10,000A, however we would recommend our APM CT Meter for most current transformer applications.

When using the Amp Meter ensure any CT has a maximum input of 5A and is 1% accurate, therefore the reading is accurate to +/- 50mA. When selecting a CT, use one with a primary that matches you maximum input and a secondary (output) of 5A.


Unique LCD Display

The LCD display boasts a super-wide viewing angle, which significantly improves visibility and can be read from almost any position. It is ideal for panel builders, system integrators and maintenance or electronic engineers that require a modern, versatile panel mount digital amp meter. The APM’s slim-line design requires only 53mm depth for panel mounting.
