CyberPower MBP63A2 Maintenance Bypass PDU
The CyberPower MBP63A2 is a rugged, 63A Maintenance Bypass Power Distribution Unit designed for data centers and high-demand electrical environments. It ensures uninterrupted operation for your mission-critical equipment by allowing a seamless power transfer from UPS power to utility power during UPS maintenance, battery replacements, or system upgrades.
With its 2U form factor and flexible mounting options, the MBP63A2 is a vital component for maintaining 100% uptime in professional IT infrastructures.
Key Performance Features
Seamless Maintenance: Allows qualified personnel to bypass the UPS without shutting down connected equipment.
Manual Bypass Switch: Features a clear “Normal” vs. “Bypass” selector. LEDs indicate at a glance which power source is currently active.
Integrated Safety (MBP Detection): Includes a detection cable that communicates with the UPS. When the bypass cover is removed, it signals the UPS to transfer to internal bypass mode, preventing potential hardware damage.
Industrial Durability: Encased in a rugged metal housing that resists impacts and abrasions, making it suitable for both standard racks and challenging industrial sites.
Versatile Mounting: The 2U form factor supports horizontal or vertical rack mounting, wall mounting, or tower configurations.
