OverviewTDK Corporation announces the HVC50, a high-voltage DC contactor designed for connecting or disconnecting lithium-ion battery systems up to 1500 V for traction, energy storage systems (ESS) and megawatt charging systems (MCS). The HVC50 provides fast DC disconnection, bidirectional main terminals and features designed for safe arc quenching and reliable integration in demanding industrial and vehicular environments.
Main applications- Traction battery systems
- Energy storage systems (ESS)
- Megawatt charging systems (MCS)
Main features and benefits- Maximum cut-off: 1000 A (DC) at 1500 V (DC)
- Continuous operation: up to 750 A (DC) at 1500 V (DC)
- Bi-directional main terminals (no polarity required)
- Auxiliary mirror contact for switching feedback (IEC 60947-4-1)
- Dual-coil design for 12 V or 24 V operation
- Coil termination protected with TVS diode
- RoHS compatible
