Selecting high voltage DC contactor relays
Speed to market can make or break a company’s competitive chances in the global electric vehicle (EV) market. However, in the rush to entry, quality and functionality cannot be left behind. A deep understanding of the dos and don’ts with high voltage DC relays can prevent issues and enable a high-performance design that wins customer satisfaction.
In the race to electrify vehicle designs, engineers may encounter applications having DC voltages higher than they are used to seeing. At these moderately higher voltages (48 to 1800 V), a properly selected contactor electrical relay can mean the difference between catastrophic failure and success. A proper system design will reduce the risk of a relay erupting, starting a fire, or disabling a critical function.
In this whitepaper by Littelfuse, you can explore what considerations should be put into finding the right high voltage DC contactor relays for your EV design including, relay technology, key specifications, and special problems of high-voltage DC applications.
