Description

Dual Moving Iron AC meter – EA19D

 
Dual Moving Iron AC meter – EA19D DESCRIPTION
EA19D meter is destined for the measurement of AC currents for frequency range of 15…400Hz and voltages in the frequency range of 15…100Hz.

Meter has two different movements and two different scales. Any combination Ammeter / Ammeter, Voltmeter / Voltmeter and Voltmeter / Ammeter is possible.
Dual Moving Iron AC meter APPLICATION

The panel electromagnetic meter with a double measuring system is designed to measure AC current with a frequency of 15 … 400 Hz and a voltage of 15 … 100 Hz. The meter will be used, among others, in switchgears, control cabinets of generators and wherever there is a limited space for measuring two electrical quantities. EA19D meters are designed for mounting into panels with thickness not exceeding 25 mm in the holes 92 x 92 mm.
