Unmatched precision at 450V to 2,000VDC! The combination of USF300 resistors achieves outstanding temperature stability and low load drift.
**Ultra-Precision High-Voltage Divider that Maximizes the Limit Accuracy of DC Voltage Measurement Instruments**
The 'Type USVD' from Cadock, USA, is an ultra-precision divider that offers industry-leading accuracy in the range of 450VDC to 2,000VDC.
**Main Features**
- **Top-Level Divider Accuracy**: Boasting a maximum ratio tolerance of 0.01% and a ratio temperature coefficient of 2 ppm/°C, it eliminates deviations in the division ratio caused by environmental changes and current flow to the utmost extent.
- **Carefully Selected Element Structure**: By optimally pairing and coupling ultra-precision resistors from the 'USF300 series', it ensures outstanding matching performance.
- **Long-Term Stability**: The aging change (shelf ratio stability) is exceptionally low, at less than 10-20 ppm/year in the first year.
- **Applications**: Ultra-high-precision digital multimeters, standard calibration devices, medical precision measuring instruments, and research and development measurement equipment.
**Main Specifications**
- **Maximum Operating Voltage**: 450V / 650V / 1,400V / 2,000VDC
- **Total Resistance Values**: 1MΩ / 2MΩ / 10MΩ / 20MΩ
- **Division Ratios**: 100:1 / 1,000:1
- **Ratio Tolerance**: 0.01% / 0.025%
- **Ratio Temperature Coefficient**: 2 ppm/°C (-40℃ to +85℃)
