HVC27 High-Voltage Contactors

TDK HVC27 High-Voltage Contactors safely and reliably switch off continuous DC currents of 300A to 500A and operating DC voltages of up to 1000V in lithium-ion batteries in ≤20ms. This achievement is due to the gas-filled ceramic arc chamber. These high-current contactors are available with single or double coil and working voltages of 12V or 24V. The single-coil version requires 6W in continuous operation, and the dual-coil version only 4W. The service life for resistive opening (450V/300A) includes 1500 operations for the single-coil variant and 2000 operations for dual-coil devices. At 750V/300A, these values are 150 and 1000 opening cycles, respectively. An optional Hall-effect sensor for the auxiliary contact is used to detect the switching state of the main contacts.
