H05VV-F 3×1.5mm² Locking C19 to Locking C20 IEC320 Power Cord for PDU Server
Product Description
LOCK c19 to c20 power cord
H05VV-F Locking C19-to-C20 Power Cable – Locking connectors on both ends to prevent disconnection, 16A/250V high-power rating, 3×1.5mm² pure copper conductors, CE/VDE certified, specifically designed for high-reliability power connections in data center PDUs, servers, and core switches.
About the product
Specification
Features: Similar in appearance to the standard C19, but incorporates a locking mechanism that securely locks an inserted C20 plug in place. In industrial applications, some designs support rotary locking (e.g., Legrand products) or sliding unlocking (e.g., S-Lock, IEC-Lock).
Typical Applications: Installed at the power input terminals of equipment such as servers, switches, and blade enclosures. It ensures that power cords do not come loose during equipment maintenance or cabinet vibrations, preventing business-critical operations from being interrupted by power outages.
Features: As a “plug” designed to be inserted into a C19 port, it features locking mechanisms or latches in addition to standard prongs. Some highly compatible locking C20 plugs (such as S-Lock) are designed to fit any standard C20 outlet without requiring specialized equipment. For some brands (such as APC), the locking function requires a dedicated PDU to operate.
Typical Applications: Typically connected to the end of a power cord, it is inserted into the output port of a PDU (Power Distribution Unit) or UPS to provide a reliable power input for downstream C19 connections.
About the product
1. Dual locking connectors prevent accidental disconnection due to vibration
Both C19 and C20 ports are equipped with integrated locking mechanisms, with an extraction force exceeding 100N. Once locked, the connectors cannot be easily disconnected, ensuring that power to critical IT equipment remains uninterrupted even when cabinet fans are vibrating continuously or cables are accidentally pulled. This eliminates the risk of server downtime caused by accidental power disconnection.
2. 3×1.5mm² pure copper conductors, 16A/250V supports 4000W high power
High-purity stranded copper conductors with a cross-sectional area of 1.5mm² provide low resistance and efficient power transmission. Rated at 16A/250V with a continuous power rating of up to 4000W, it perfectly meets the power supply requirements of high-power equipment such as blade servers, core switches, and storage arrays in high-density cabinets.
3. H05VV-F flexible PVC jacket, heat-resistant, flame-retardant, and easy cable management
H05VV-F cables comply with the HD 21.5 S3 / VDE 0281-5 standard. The flexible PVC jacket facilitates routing through cabinet cable trays and cable management arms, and is heat-resistant, oil-resistant, and abrasion-resistant. With a flame-retardant rating of VW-1 / IEC 60332-1, it ensures electrical safety within the cabinet. The standard 2-meter length is compatible with mainstream cabinet layouts.
4. CE/VDE certified, internationally compliant for worry-free export
With dual CE and VDE certification, the product complies with the EU Low Voltage Directive and German electrical safety standards. It can be exported seamlessly to Europe and other markets that recognize CE/VDE certification, simplifying the global compliance process for equipment manufacturers. The C19 and C20 connectors comply with the IEC 60320 standard.
Application
Designed specifically for high-reliability power connections for data center PDUs, servers, and core switches
