KV-R Series Portable Dividers
- RATIO ACCURACY <0.01% dc
- LOW TEMPERATURE & POWER COEFFICIENTS
- RUGGED CONSTRUCTION
- WITH INTEGRAL METER
- NEW MODEL KV-30R WITH AC CAPABILITY
Ohm-Labs’ –R series are precision portable high voltage dividers. Ohm-Labs has added a new model to measure up to 30 kV dc and 20 kV ac rms (50/60 Hz).
The KV-R dividers use precision, wire wound resistors which are selected and matched to reduce errors caused by high voltage. They may be operated continuously up to their full rated voltage without damage.
A front panel meter provides indication of applied voltage. The meter requires no external power.
Three standard models are available: the original design KV-5R and KV-10R, and a new model KV-30R.
All KV-R models have an impedance of 1000 ohms per volt. Leakage and corona effects have been minimized by careful internal design and layout.
All dividers are supplied with ISO 17025 accredited, traceable reports of calibration up to full rated voltage.
Special ratios or case styles can be supplied upon request.
For the highest accuracy in both DC and low frequency AC measurement, please see our HVA series of laboratory dividers. For compact precision dividers upto 10 kV, please see our model KVVB.
Ohm-Labs offers calibration and repair service to high voltage dividers.
