- EXCELLENT STABILITY
- COMPACT SIZE
- LOW TEMPERATURE COEFFICIENT
- 0.025 % RATIO ACCURACY
Originally designed by Julie Research Laboratories, the KVVB is an economical, stable, highly accurate voltage divider. It allows measurement of dc voltages up to 10 kV.
A recent design upgrade has upgraded the output terminals to low thermal emf 5-way binding posts, and has improved standard specifications to conform to the higher precision –C option. Now all models feature < 0.025 % ratio accuracy as standard ratio acccuracy. The original JRL design is still available and supported.
The KVVB consists of precision resistors encapsulated in silicon resin in a diallyl phthalate housing. Careful internal layout and design reduce leakage and corona effects.
The KVVB has a temperature coefficient of resistance (tcr) of less than 5 ppm / °C. The KVVB is equipped with gold plated tellurium copper binding posts for ground, low and output. The ground and low are internally connected. High voltage input is with a ceramic post terminal with a 10-32 threaded post. The input terminal is fitted with an anti-corona ball for reduced risk of arcing. Four mounting holes are provided at the corners.
All Ohm-Labs high voltage dividers are supplied with ISO 17025 accredited, traceable calibration.
The KVVB is a compact, rugged divider.
Special ranges and ratios are available by special order to suit customer measurement needs.
Please see our KV-A portable dividers to 30 kV dc / 20 kV ac, and our HVS High Voltage Standard for the highest precision measurement applications.
Ohm-Labs offers ISO17025 accredited calibration of high voltage instruments by all manufacturers.
