In the world of high voltage engineering, precision and reliability are paramount. EAK’s HVR series of high voltage resistors is designed to meet the most demanding requirements across industries such as X-ray technology, high voltage measurement systems, and energy transmission. These thick-film resistors offer exceptional performance, combining durability with low inductance and pulse-proof capabilities, making them an ideal choice for advanced applications.
Key Features of EAK’s HVR Series
The HVR series stands out due to its robust design and superior electrical characteristics. With resistance values ranging from 10 KΩ to 50 GΩ and a tolerance as tight as ±0.5%, these resistors ensure accurate and stable performance even under extreme conditions. Their temperature coefficient ranges from 25 ppm/°C to 200 ppm/°C, allowing operation in environments where thermal fluctuations are common. Additionally, their voltage coefficient is impressively low at <2 ppm/V, ensuring minimal resistance variation under changing voltage loads.
One of the standout features of EAK’s high voltage resistors is their dielectric strength, exceeding 1,000 V in standard conditions. This makes them suitable for both air and oil-based insulation setups, with models rated up to 81 kV in oil environments. The resistors also exhibit excellent long-term stability, with a maximum resistance change of just 0.25% under moisture, thermal shock, and long-term load tests.
Versatile Design and Ratings
EAK offers the HVR series in multiple configurations to suit various application needs. Available in lengths from 27 mm to 153 mm, each model delivers power ratings between 3.8 W and 17 W, depending on size and configuration. They operate within a wide temperature range of -55°C to +175°C, ensuring functionality in harsh industrial or outdoor environments. The round body design and brass end caps provide mechanical stability and easy mounting options, including M4 threaded connections for secure installation.
These resistors are engineered to withstand overloads up to 1.5 times their nominal power rating for short durations (up to 5 seconds), enhancing their suitability for pulsed high-voltage applications. Their epoxy-based coating further protects against environmental stress, offering long-lasting protection in humid or chemically aggressive settings.
