Compared to TC 2ppm/°C, the allowable tolerance is 0.01%! Pressure divider 'USVD'

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℃)
