The voltage tolerance of a 24VDC auxiliary power supply is ±10%.
The voltage tolerance of a 100~120VDC auxiliary power supply is %.

The input range is approximately ±10% of the central frequency.
Example: In the case of 400Hz, input 360~440Hz.
Transducers with positive/negative bidirectional output based on the central frequency can also be manufactured.
However, the manufacturable ranges in regard to output are ±0.1~±5mA and ±50mV~±10V.
Example: Input 45~50~55Hz; Output -1~0~1mA, -5~0~5V.
When only auxiliary power supply is applied, positive-side burnout output occurs.
