Model MP & ML Power factor and Phase angle meters, designed of a balance type with universal & flexible application feature, can be applied to measure single phase 2 or 3 wires, 3 phase 3 wires & 3 phase 4 wires only under the specified terminal connection. The units accept ac voltage & current inputs with detection of phase relation between the measured phase voltage & phase current of power factor COSØ for MP & phase angle for ML. The designed specifications compliant ANSI, DIN & VDE standards with full protection for unusual surge intrusion and input over assuring reliable operation.
