MOD-7S12A

TRUE-RMS – 3½ DIGITS AMMETER
The MOD-7S12A is an advance, loe cost True -RMS ammeter which computes the true – root – mean – square value of complex signals. AC coupling allows the measurement of the component (or ripple) from a signal with both AC and DC componets.
DC coupling allows the measurement of total rms or “heating value” including DC and AC components to over 30kHz. Maximum crest factor (Ap/Arms) is 3:1.
Screw terminal allow the selection of AC/DC coupling. True -RMS ammeter are especially useful in monitoring voltage supply to motors or heaters cotrolled by SCR or Triac circuit. For AC currents over 5a and isolate the meter to avoid common mode problems.The current transformer specifed by turns ratio such as 200:5.
