Power Distribution Unit PDU12 (220V UK 12 ways)

SGCCTV-PDU12 12-Way Power Distribution Unit with Auto Circuit Breaker for 42U Server Rack Singapore

The SGCCTV-PDU12 is a 12-way rack Power Distribution Unit (PDU) designed for vertical installation inside 42U server racks, CCTV racks and network cabinets.

Its purpose is to provide centralized AC power distribution for rack-mounted equipment while incorporating an automatic circuit breaker for overload protection.

Why Install the PDU Vertically in a 42U Rack?

A vertical PDU is particularly useful in a full-height 42U server rack because it can be mounted along the side or rear of the cabinet instead of consuming valuable horizontal rack space.

Horizontal PDU

May occupy 1U or more of equipment space.

SGCCTV-PDU12 Vertical PDU

Mounted vertically inside the rack, helping preserve rack units for:

NVRs • Servers • PoE Switches • Firewalls • Fiber Equipment • Patch Panels • UPS Systems

This is commonly described as a Zero-U PDU arrangement, provided the rack has suitable vertical mounting space.

12-Way Centralized Power Distribution

One PDU can provide organized power distribution to multiple rack devices.

Typical 42U CCTV/network rack:

UPS
↓

↓
NVR
PoE Switch
Core Network Switch
Fortinet Firewall
Fiber Switch
KVM
Server
Monitor/Console Equipment

This is substantially cleaner than installing multiple domestic extension sockets throughout a professional equipment rack.

Auto Circuit Breaker Protection

The integrated auto breaker provides an additional protective point for the PDU circuit.

If an abnormal overload occurs, the breaker is intended to disconnect the circuit rather than allowing excessive current to continue through the PDU.

However, a PDU circuit breaker should not be treated as a replacement for the building's correctly designed electrical protection.

A professional rack should consider:

Upstream MCB/RCBO/RCCB → UPS → Rack PDU → IT Equipment

depending on the site's electrical design and equipment requirements.

Recommended with UPS

For critical CCTV, network and server applications, the PDU can be installed downstream of a properly sized UPS:

NVR + Switch + Firewall + Server + Network Equipment

This provides centralized rack distribution while the UPS supplies backup power to the connected critical equipment.

The UPS capacity must be calculated from the actual combined load, required runtime and future expansion.

Ideal for CCTV Equipment Racks

The SGCCTV-PDU12 is suitable for organizing power to:

HIKVISION NVR

DAHUA NVR

Hanwha Vision NVR

PoE Network Switches

RUIJIE Network Switches

Fortinet Firewall

Fiber Media Equipment

KVM Switches

CCTV Servers

Access-Control Network Equipment

Rack Cooling Accessories

Other compatible IT equipment

Professional 42U Rack Design

A typical CCTV/server rack can be arranged as:

42U SERVER RACK

Top
Fiber Patch Panel
Cat6 Patch Panel
Cable Management
Core Network Switch
PoE Switches
Firewall / Router
NVR / VMS
Servers
KVM
UPS
Battery Equipment

Vertical Side / Rear:

This keeps AC power distribution separated and organized while preserving front rack space.

PDU Load Calculation Is Important

Do not determine PDU suitability simply by counting the number of outlets.

For example, having 12 outlets does not mean 12 high-power devices can automatically operate at maximum load simultaneously.

The calculation should consider:

Total Equipment Wattage

PDU Rated Current

Circuit Breaker Rating

Input Plug Rating

Supply Circuit Rating

UPS Output Capacity

Cable Rating

Continuous Operating Load

For professional installations, the PDU's electrical rating must be equal to or greater than the designed load and must remain within applicable electrical requirements.

CCTV Rack Example

For a commercial CCTV system:

Fortinet Firewall
↓
RUIJIE Core / Managed Switch
↓
PoE Switches
↓
HIKVISION / DAHUA NVR
↓
Storage / VMS Server

Power architecture:

Firewall + Switches + NVR + Server

This provides a much more organized approach to rack power management.

PDU vs Ordinary Extension Socket

For a professional 42U server rack, a rack-mounted PDU provides several practical advantages over loose consumer extension strips:

Secure Rack Installation

Cleaner Cable Management

Centralized Power Distribution

Dedicated Rack Layout

Integrated Circuit Protection

Reduced Loose Power Adaptors and Extension Strips

Easier Maintenance

Better Equipment Identification

A properly installed rack should make both the network path and power path easy for technicians to trace.

Recommended Installation Practice

For a professional installation:

1. Calculate the total rack load

2. Confirm PDU maximum current and breaker rating

3. Confirm UPS capacity

4. Mount PDU vertically inside the 42U rack

5. Separate AC power cables from data/fiber where practical

6. Label each PDU outlet

7. Avoid cascading extension strips

8. Keep cables properly dressed and secured

9. Leave allowance for future equipment

10. Document which PDU outlet supplies each rack device

Example:

PDU-01 → Firewall
PDU-02 → Core Switch
PDU-03 → PoE Switch 1
PDU-04 → PoE Switch 2
PDU-05 → NVR 1
PDU-06 → NVR 2

This greatly simplifies future troubleshooting.
