Hitachi Energy 560CVD03 Multimeter

560CVD03 Multimeter, 1A/5A, 3U3I

CT/VT Interface with 3 Voltage and 3 Current Inputs for Direct Monitoring of 3-Wire 85.... .400 VAC

1/5 A input for AC transformer

RTU500 serial interface (RS-485)

APPLICATIONS

The multimeter 560CVD03 is used to monitor input signals from three independently phased 3-wire or 4-wire connections.

Voltage, current and power can be measured directly for each phase and a number of other parameters can be derived via software. The measurement results are transmitted to the RTU560.

Several versions are available:

Power measurement display

It automatically switches the screens of the measurement page and displays each screen for 6 seconds.

Six seconds.

If changed to key mode, each screen will automatically display 240 seconds. Scroll mode can be set with the RTUtil560.

Features

Multimeters are microprocessor-based Intelligent Electronic Devices (IEDs) used to measure current, voltage, power, and energy.

Derived parameters are calculated once in 500 milliseconds and then scaled according to user-programmed constants for current and voltage transformers.

The current and voltage inputs of the 560CVD03 are connected only through the appropriate transformers (see Figures 3 and 4).

The multimeter can be mounted on a 35 mm DIN rail.
