Power Distribution Units (PDUs) are the key devices in Data Center and Server Racks. Mounted in standard 10 or 19 inchracks, these devices ensure your servers, switches, and storage systems get reliable, organized power. Let’s break down why PDUs matter, how they work, and how to choose the right one.
A PDU is standard Rack-Mount power strip. Unlike household power strips, PDUs handle high voltages and support dense equipment configurations. Webit team mainly split them into 3 types: Basic model , Metered model and Smart PDUs. They plug into your main power source (like a UPS or wall outlet) and distribute electricity to multiple devices in the rack.
Key Advantage: Organization & Reliability
No More Tangled Cables: PDUs mount vertically or horizontally in racks, keeping power cords neat and accessible.
Prevent Overloads: Built-in circuit breakers protect against electrical surges and overloads.
Maximize Uptime: Ensure critical equipment stays powered, reducing downtime risks.
Basic PDUs
What they do:Power distribution
Best for: Small setups where cost is key and no special request
Example: 12-outlet vertical Schuko PDU with 16A rating.
Metered PDUs
What they do: Display real-time power usage (amps, watts) via a built-in screen.
Best for: Capacity planning and avoiding circuit overloads.
Example: Metered PDU showing total rack power draw.
Monitored (Smart) PDUs
What they do: Monitor per-outlet or total power usage and send data via network (SNMP, TCP/IP, TELNET).
Best for: Remote monitoring, energy efficiency reports, and alerts.
Example: IP-enabled PDU with web interface for tracking usage trends.
Switched PDUs(Smart) PDUs
What they do: Allow remote on/off control of individual outlets via network.
Best for: Rebooting frozen devices without visiting the rack.
Example: Switched PDU used to power-cycle a server from a smartphone.
Data Centers: Power hundreds of servers in a single rack.
Network Closets: Feed switches, routers, and firewalls.
Audio/Video Racks: Power mixers, amplifiers, and streaming gear.
Industrial Control Systems: Reliable power for manufacturing or lab equipment.
Q1: Can I plug a PDU into a regular wall outlet?
Yes, it can be used in daily life.
Q2: What is the difference between 10-inch and 19-inch PDUs?
Only the mounting width! 19-inch is the global rack standard (e.g., server racks). 10-inch PDUs fit smaller telecom/network racks.
Q3: Do PDUs provide surge protection?
Available, Webit produce the PDUs as per customer request, Surge protector is one of the functional kits.
Q4: How many outlets do I need?
Count your rack devices, then add 25% for future expansion. PDUs offer 8–48+ outlets.
Q5: Can smart PDUs save energy?
Absolutely! By identifying underused devices and enabling remote shut-offs, they cut wasted power.
