OMR card - IN.15

IN.15 - 3-phase wattmeter

Plug-in card for measurements of 3-phase power, voltage (VRMS), current (ARMS), frequency (Hz), power P, Q, S, harmonic distortion, angle and cos fi for the OMR 700 is fully isolated from the internal bus with a galvanic isolation also between individual inputs.
The design of the cards allows their use at any position in the device. If during the use of the device appear new requirements to increase the number of inputs or outputs, just order another card and insert it into a free slot. In this manner the device can "grow" with your requirements.
