SHA-512 is part of the SHA-2 family of hash functions with a 512-bit output and a 256-bit security level.
SHA-512 is one of the algorithms in the SHA-2 sha-2 family of cryptographic hash functions defined by NIST. It processes input in 1024-bit blocks, and has a 512-bit output, for a 256-bit security level. It is defined in terms of operations on 64-bit words.
