Huawei PAC600S12‑CB 600 W AC & 240 V DC Power Module

The Huawei PAC600S12‑CB is a high‑quality 600 W AC & 240 V DC power module engineered for enterprise‑grade access and aggregation switches. Designed for systems requiring flexible power options, this unit supports a wide input range from 100 – 240 V AC at 50/60 Hz and 190 – 290 V DC, ensuring compatibility with global power environments. It provides a 12 V DC output at up to 50 A, delivering a total of 600 W of stable power to the host chassis, and is equipped with a built‑in fan for active cooling via a back‑to‑front airflow path, with exhaust directed through the power panel for optimized thermal performance. The “CB” airflow designation is ideal for rack architectures where chassis draws air from front to back. Comprehensive protections include input undervoltage/overvoltage, output overcurrent/overvoltage, short‑circuit, and overtemperature safeguards. The module also supports hot‑swapping, enabling replacement without powering down the host device — critical for enterprise uptime. Compatible with a range of Huawei CloudEngine and S‑series switches, it’s a reliable choice for network power redundancy and expansion.

Key Features:

• 600 W Output: Provides up to a full 600 W DC output (12 V/50 A) for high‑power chassis.

• Wide Input Range: Works with 100 – 240 V AC and 190 – 290 V DC sources, suitable for global installations.

• Back‑to‑Front Airflow (“CB”): Engineered for chassis airflow that exhausts through the power panel side.

• Hot‑Swappable: Replace or install without shutting down the switch.

• Comprehensive Protection: Includes overcurrent, overvoltage, short‑circuit, and overtemperature protection.
