Amplifier
Amplifier M210А1 is used to expand the functionality of the Voltage Transformer Test Set M210/M211 during the calibration and verification of low power voltage transformers (LPVT) with analog output in the form of an alternating voltage.
M210А1 performs precision amplification of the secondary voltage of LPVT and supplies it to the input of Voltage Transformer Test Set M210/M211.
FEATURES AND BENEFITS
- Continuous range of rated secondary voltages of verified LPVT
- High conversion accuracy
- Simple use by intuitive user interface
- Storage of individual voltage settings
- Possibility of using with automated VT calibration system
APPLICATIONS
M210A1 is used by:
- Manufacturers of LPVT
- Calibration Laboratories
- Metrology Institutes
