EAK High - Voltage Resistors: Precision and Durability for Demanding Applications

 

In the world of electrical components, EAK's high - voltage resistors stand out as a reliable and high - performance choice. Inspired by the excellence of resistors like the HVR 968 series, EAK has developed a range of high - voltage resistors that are tailored to meet the most challenging requirements.

These high - voltage resistors are thick - film resistors, engineered with heavy - duty construction and high dielectric strength. This makes them ideal for a wide variety of applications, including X - ray technology, high - voltage measuring technology, and energy transmission systems. Whether it's dealing with high - voltage pulses or registering constant high voltages, EAK's high - voltage resistors deliver consistent and accurate performance.

EAK's high - voltage resistors offer a wide range of resistance values, similar to the standard values of 10 K, 100 K, 1 M, 5 M, 10 M, 25 M, 50 M, 100 M, 1 G, 2 G, 5 G, with the flexibility to provide other values upon request. The tolerance levels are impressively tight, ranging from 0.5% to 20%, allowing for precise control in different electrical circuits. The temperature coefficient, which can vary from 25 ppm/°C to 200 ppm/°C, ensures stable performance across a wide temperature range of −55 °C to +175 °C during operation and −55 °C to +100 °C for storage.

The voltage coefficient of EAK's high - voltage resistors is less than 2 ppm/V, minimizing the impact of voltage changes on the resistance value. With an insulation resistance of 10,000 MΩ (at 500 V, 25 °C, and 75% relative humidity) and a dielectric strength of the insulation greater than 1,000 V (at 25 °C and 75% relative humidity with a maximum ΔR/R of 0.25%), these resistors provide excellent electrical insulation and can withstand high - voltage environments.

They also have remarkable stability under various conditions. The thermal shock resistance, moisture resistance, and long - term stability all exhibit a maximum ΔR/R of 0.25%. Additionally, the overload capacity of 1.5 x P[nom] for 5 seconds (not 1.5 x V[max]) ensures that the resistors can handle short - term high - power demands without failure.

EAK's high - voltage resistors come in different types, each designed to meet specific requirements. For example, they are available with different power ratings, voltage ratings for air or oil operation, and connection types. The connection type includes brass caps, which can be wired, and are optionally available with an inner thread M4 for easy installation. The cover options, such as epoxy - based varnishes (glass or silicone - based encasing), provide protection and enhance the durability of the resistors.

In conclusion, EAK's high - voltage resistors are a top - tier choice for applications that demand precision, reliability, and high - performance in high - voltage environments. Their wide range of specifications, excellent stability, and diverse design options make them suitable for a multitude of industries.https://www.eak.sg/blogs/high-voltage-resistors-precision-and-reliability-for-demanding-applications/

Energy Production in Maglev Systems and the Role of EAK Liquid-Cooled Resistors

Image
Magnetic levitation, commonly known as maglev, represents one of the most advanced transportation technologies of our time. By utilizing powerful electromagnets to lift and propel trains above a guideway, maglev systems eliminate friction, enabling unprecedented speeds and smooth rides. However, behind this seemingly effortless gliding lies a complex energy production and management system. One critical component of this system is the EAK liquid-cooled resistor , which plays a pivotal role in ensuring the safety, efficiency, and reliability of maglev operations. Where Does the Energy in Maglev Systems Come From? The energy required for maglev systems originates from electrical power supplied by the grid. This energy powers two primary components: the electromagnets responsible for levitation and the linear motors that drive propulsion. Levitation Energy : Maglev trains use superconducting magnets or electromagnets to create a magnetic field strong enough to lift the train off the guide...

Understanding Braking Choppers and Liquid-Cooled Resistors in Industrial Drives

Image
In modern industrial automation and motor control systems, managing energy during deceleration is critical for system safety, efficiency, and reliability. Two key components that play a vital role in this process are the braking chopper and the liquid-cooled resistor . These elements work together to ensure stable operation of variable frequency drives (VFDs), especially in applications involving high inertia loads or frequent stopping and reversing, such as elevators, cranes, and conveyor systems. What Is a Braking Chopper? A braking chopper , also known as a brake斩波器 (zhǎnbōqì), is an electronic switch integrated into the DC bus of a VFD. Its primary function is to protect the drive from overvoltage conditions that occur when the motor acts as a generator during deceleration or downward motion (e.g., in lifting mechanisms). When a motor slows down, it feeds regenerative energy back into the drive’s DC link, causing the DC bus voltage to rise. If left unchecked, this voltage spike ca...
