Trumeter 数字面板仪表, 测量安培、频率或功率、电压, 4位数字, 切面68mm宽 x 68mm高, 45mm深

The APM-MAX-M21 is a multi-function panel meter designed for 0-600V DC/AC applications. It is configurable as an ammeter, voltmeter, frequency meter or power monitor (Watts, VA & Power Factor).

The unique display combines the instant visual representation of analogue with the accuracy of digital for instant recognition and precision measurement. It has a 25% larger screen than our standard APM, incorporating a 60-segment bar graph display, large 4 digit display, separate Starburst display area for messages and alarm info and a full colour RGB dynamic backlight for instant alerts.
Programmable Scaling and Range (min and max), annunciators, backlight colour and intensity, two independent alarm set-points, two independent digital outputs, a 4-20mA analogue output and serial MODBUS® RTU for communication with other components in a system as well as an IP65 rating.

The positive display, designed for bright environments, features black figures on a colour-changing background.
