Series 512 and 522: Compact Current and Voltage Transducers
The Series 512 and 522 transducers are designed for precise measurement of sinusoidal currents and voltages, offering high accuracy and robust performance in industrial applications. These transducers are ideal for measuring nominal input currents (0.05–16A) and nominal input voltages (100–720V) while providing galvanic isolation and reliable signal conversion.
Key Features:
- Compact Design: Ultra-slim 22.5 mm housing for efficient space utilization.
-
Wide Measurement Range:
- Current: 0.05–16A (higher currents with external transformers).
- Voltage: 100–720V (higher voltages with external transformers).
