Application Notes
IEC 60320 C20 to C21 VS-Lock power cords are engineered for high-reliability applications where accidental disconnects are not an option. The C21 connector (S-Lock) features a retention system designed to work with any C20 or C22 inlet. The C20 (V-Lock) is designed to work with both V-Lock and W-Lock inlet designs, providing broad compatibility across a wide range of PDUs and equipment without requiring a single proprietary standard.
The C20 plug on the source end mates with standard C19 outlets on rack PDUs and UPS systems, while the C21 connector secures to any compatible C20 or C22 inlet on the equipment side. This dual-standard compatibility makes VS-Lock cords a flexible choice for mixed deployments and environments where PDU and equipment brands may vary.
C20 to C21 VS-Lock cords are ideal for servers, switches, storage arrays, blade chassis, and high-density power paths in data centers, colocation facilities, and mission-critical environments where connection security and uptime are paramount.
Product FAQs
What is a VS-Lock power cord?
A VS-Lock power cord has retention system engineered to work with both V-Lock and W-Lock inlet designs. It locks to any compatible C20 or C22 inlet, preventing accidental disconnection in high-reliability applications.
What is the difference between VS-Lock, V-Lock, and W-Lock?
V-Lock and W-Lock are two locking connector standards used across different PDU and equipment brands. VS-Lock is designed to be compatible with both, making VS-Lock cords a flexible choice for mixed environments where PDU and equipment manufacturers may vary.
