The H72 series panel meters are used for metering.
1. 72 x 72 mm dimension
2. For amperemeter, with a direct connection, the maximum current can reach 50 A in AC circuit, while maximum current is 20 A in DC circuit
3. For voltmeter with a direct connection, the maximum voltage can reach 600 V in both AC and DC circuits
4. Accuracy for amperemeter and voltmeter is class 1.5 and accuracy of frequency meter is class 1.0
H72 panel meters are used for measuring current, voltage, and frequency; they are also mainly used as indicating instruments for high or low-voltage switch cabinets, power supply cabinets, control cabinets, and other electric-control facilities in the AC transmission circuit system.
