3-Phase AC Voltage Transducer, 0~120V/450V to 600V

The SUCH 3-phase AC voltage power transducer converts three-phase AC voltage signals into proportional standard analog or RS485 outputs for voltage measurement, monitoring, and control. It supports 0–120V, 0–300V, 0–450V, and 0–600V AC inputs, with analog output options of 0–1mA, 0–10mA, 0–20mA, 4–20mA, 0–5V, 1–5V, and 0–10V. With a response time of ≤400ms and accuracy of 0.2 or 0.5, it provides timely and reliable voltage signals for industrial electrical systems. Input, output, power supply, and enclosure are electrically isolated, making it suitable for switchgear, power distribution panels, motor control centers, and energy monitoring systems.

Note: This voltage transducer measures three-phase AC voltage for monitoring and control of three-phase power systems.

Feature

• Wide voltage input range — Supports 0–120V, 0–300V, 0–450V, and 0–600V three-phase AC inputs, with custom ranges available for different system voltage requirements.
• Multiple output options — Provides 0–1mA, 0–10mA, 0–20mA, 4–20mA, 0–5V, 1–5V, 0–10V, or RS485 output for direct integration with PLC, DCS, SCADA, and other monitoring or control systems.

Calibration Instructions

PWR – Power indicator light
SPAN – Full-scale (span) calibration potentiometer
ZERO – Zero calibration potentiometer

Note: Calibration potentiometers are for professional instrument calibration only. Adjustment by unauthorized personnel is prohibited.

Calibration Steps

1. Zero Calibration: With no input signal applied, adjust the "ZERO" potentiometer on the front panel until the output signal reads zero (e.g., 0mA or 4mA).
2. Span Calibration: With the rated input signal applied, adjust the "SPAN" potentiometer on the front panel until the output signal reaches the rated value (e.g., 20mA).
