HPE Hardwire -48VDC 3.5M 2000-2200W Power Cord - P73874-B21

HPE P73874-B21 -48VDC Hardwire Power Cord

Overview

The P73874-B21 is a -48VDC hardwire power cord rated for 2000–2200W delivery over a 3.5-meter run. This accessory connects high-capacity DC power distribution to surveillance and network infrastructure where direct wiring replaces standard connectors — the install scenario for enterprise data centers, telecom shelves, and distributed outdoor surveillance networks that cannot tolerate plug-disconnect points. The -48VDC standard is foundational in telecom and mission-critical backup systems; this cord bridges bulk power to modular equipment racks without intermediate conversion.

Compatibility

Verify compatibility with your target equipment's power input specification: -48VDC hardwire terminals rated for 2000–2200W input. Common use cases include HPE Intelligent Power Distribution Units (PDUs), backup power systems, and surveillance infrastructure operating on -48VDC bus architecture. Do not assume compatibility across brands or voltage standards — -48VDC is distinct from standard AC mains and +48VDC systems. Check your equipment datasheet for exact DC input terminals and amperage rating before order.

Installation Notes

The 3.5-meter length suits wall-mounted cabinet runs and intermediate rack-to-distribution distances typical in server rooms and telecom closets. Hardwire termination requires direct crimping or soldering to equipment terminals — no standard barrel connectors are present. Ensure qualified personnel perform termination to avoid arcing and thermal stress at the connection point. Verify wire gauge and terminal contact area meet or exceed the 2000–2200W capacity specification; undersized terminal crimps are a common failure mode on high-power DC circuits. Do not route the cord through areas subject to mechanical stress, chemical exposure, or high ambient temperatures — -48VDC systems often operate near battery banks and chargers that generate heat and hydrogen gas.
