Low Bias Fiber Ring Gyro Three Axes Optical Gyro
This product is a three-axis fiber optic gyro, The fiber ring and circuit acquisition board are designed separately,
which can avoid the influence of the circuit temperature changing to affect the fiber accuracy. We can provide
customers with separate three-axis gyro, and we can also customize the installation to the structure according
to customer requirements to complete the three-axis calibration.
The product is powered by + 5V DC power supply and does not need negative power supply. Its power supply requirements are as follows: Table Shown:
| Serial number | Name | Request |
| 1 | Power supply accuracy | ±5% |
| 2 | Power ripple (Vpp) | 20mV |
| 3 | Supply current | >2A |
