Electric vehicles (EVs) and hybrid electric cars frequently use high-voltage contactors, sometimes known as high-voltage relays without distinction in the industry (HEV). It is an electromechanical switching device with a coil that produces a magnetic field that mechanically moves an electric contact.
a contactor is used to turn on and off heavy, high-voltage electrical equipment like motors, fans, pumps, etc. They employ a contactor because it is safer to control these large, high-voltage electrical devices indirectly and safely through a PLC than to link the PLC to the output devices directly.
An electrically controlled switch used to switch an electrical power circuit is called a contactor. A circuit that has significantly less power than the switched circuit is frequently used to control a contactor, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
The Global EV 900V contactor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
High-voltage contactors of 300 A and 500 A are introduced by TDK. The new HVC300 and HVC500 types of high-voltage contactors from TDK are an addition to the HVC series. The current capacities of the new contactors are 300 A and 500 A, respectively. They have a maximum switching capacity of 900 V DC, and units with a 1,200 V DC handling capacity are also available upon request.
When the current is turned off, arcs are safely and swiftly put out by the gas-filled switching chamber of HVC contactors. According to TDK, the arc duration is exceptionally brief due to the contactors’ incredibly quick switching speed, increasing the components’ dependably long lifespan.
In addition to photovoltaic and energy storage systems, TDK claims that the HVC series is particularly well suited for use in battery management systems, DC charging stations, and e-mobility applications.
Applications requiring high power use contactors. They are typically larger and more robust than control relays because they enable a lower voltage and current to switch a much greater power circuit, allowing them to switch higher power loads on and off for tens of thousands of cycles.
