1. Product outline
1.1 Usage of product
This single unit can measure and monitor phase voltage ×3, line voltage ×3, zero-phase voltage, frequency.
3-phase voltage can select two types, a phase voltage input product and a line voltage input product, according
to a usage. Distinction of ground fault phase can be performed by zero-phase voltage and phase voltage.
The intensive monitor united with the system is made in an addendum of analog output.
1.2 Features of product
Phase voltage input product can distinguish the ground fault phase at the case of ground fault occurrence
by measuring zero-phase voltage and a phase voltage. (However, the maximum value and the minimum value need
to be reset of DI or switch operation after a startup.)
Bar graph 1 measurement and digital 4 measurement are displayed simultaneously.
Analog output 4 circuit and alarm output 2 circuit can be taken out. (Option)
And, an output factor can be selected by setting.
Two external operation inputs are possible. (Option)
And, selection of reset input and a display change input is possible at setting.
Power supply is AC85 to 264V，DC80 to 143V (for both AC and DC uses).
The mounting method of this unit is compatible with the mounting method of conventional 110 square mechanical
meter. This unit is mounted at 2 diagonal points.
Setup of the measurement response time is possible for a phase voltage and zero-phase voltage.
(High-speed 0.05 to 5 seconds. Arbitrary settings.)
Time interval setting is possible for a line voltage.
The function which changes a measurement display to a maximum of zero-phase voltages and the minimum voltage
of each phase automatically at the case of ground fault detection is attached.
(Function ON / OFF is possible at a setting)
Analog output is with a lower limit limiter.
The backlight function is equipped (White LED backlight).
Selection of backlight on, backlight off, and auto backlight off and setting of brightness are possible.
