CtrlTech – Power Distribution Unit - PDU in UAE

Distribute network power to several devices by the CTRL Power Distribution Units (PDUs). PDU's supply power to servers, network/telecom equipment and other devices from an uninterrupted power supply (UPS), a generator or a utilities power source. The PDU depends on the output voltage, number of devices, types of outlet, and mounting options for your needs.

Load Capacity & Rack PDU Power Rating

The rack PDU power capacity versus load capacity can cause confusion. The confusion arising from an incomprehension of approval agency regulations and from the use of misleading terminology by some factories. Typical circuits can carry the maximum current in North America and use disrupters or fuses at 15A, 20A, 30A, etc. If a 20A circuit experiences more than 20A current for a period, a PDU with a 20A fuse will blow or a 20A breaker. Duration is dependent on the current magnitude and the type of fuse or circuit breaker that protects the circuit.

Circuits in North America must be loaded to a maximum capacity of 80%. Thus, for instance, a 15A circuit must not exceed 12A, a 20A circuit not exceeding 16A, a 30A circuit not exceeding 24A, etc. For a 20A loop, for example, the value of 80% is often called the derived value or the load capacity. In North America, there may be a few current carrying requirements for rack PDU vendors. The given specifications and the terminology used may vary from vendor to vendor.

  • Current line by phase: 30A
  • Current rating by stage: 24A (30A derated to 80 percent )
  • Current drawing maximum: 6 x 16A

Evident energy in VA or VA amps is specified (volts x amps). In VA, where the amps are the rated current, i.e. the derived value is specified the load capacity. The rated current (not a maximum current) of 24A is for example used to determine the load capacity (5,0 kVA) for a single-phase rack PDU with a nominal voltage of 208V and maximum line current of 30A. (208V x 24A).

It is good to know math, but when you have to repeatedly crunch your numbers, it is not always so fun. Learn how smart PDUs can devise us to understand your ability.

Distribute network power to several devices by the CTRL Power Distribution Units (PDUs). PDU's supply power to servers, network/telecom equipment


A power supply unit (PDU) supplies multiple devices with reliable network power. It does not generate and/or condition power, but delivers AC power to servers, networking hardware, telecom devices and other equipment via a continuous power source (UPS), generator or utility source.

A PDU does the same work as a power strip in its most basic form. It uses a single source, usually a wall outlet, to power a number of different devices including computers, peripherals and networking equipment. PDUs are designed to be installed in equipment racks that keep power from racking devices like servers, switches, routers or Air Condition fans within reach.

In data centres, network closets, VoIP telephone systems and industrial environments, PDUs are often used. Whilst you may be fortunate that you dry the equipment out, it will be necessary to replace the damage caused by water mostly permanently damaged. To ensure your server room is properly monitored, you need to replace expensive equipment due to preventable damage.

Do PDUs offer protection against Surge?

Power protection units from a single source are distributed to several devices, but not strictly PDUs. They are designed for use with equipment that must be protected from spikes and voltage surges without battery backup. Since these units are primarily protected from over voltages, surge protectors and PDU are not considered.

When searching for your power supply options, it is important to know as much about power strips and PDUs as possible. Both of them have their uses and in different situations most facilities use them. A power strip is likely to be enough for everything you need for less critical areas. In areas where critical business equipment is operated or where additional features are required, it is only logical to invest in a good PDU. CTRL provides you with a range of power lines and PDUs, and we are more than happy to work on your specific requirements.

Basic PDU

Distributes the AC power to multiple outputs without filtering.

Metered PDU

Distributes AC power and measures total consumption to balance the load optimally. This includes only a display, no LAN.

Monitored PDU

Spreads AC power and measures current use, whether in total or at single outlets. It includes both a display and a LAN (SNMP/Modbus/TCP) connection.

Switched PDU

Spends AC power and enables individual connectors to be switched on/off. Includes an SNMP v1 / SNMP v3 LAN connection.

Switched Metered-by-Outlet

Distributes AC power, includes a network connection and can both activate and switch on/off consumption at individual outlets. Includes an SNMP v1 / SNMP v3 LAN connection.

For horizontal mounting PDU models usually are available in 1U or 2U heights. It can also be vertically mounted, called 0U. They can be mounted on a wall or under a rack depending on the model.

For mounting in EIA-310 standard 19-inch equipment racks, horizontal PDUs are designed. They can be placed above, below or between their power components.

Vertical PDUs look like high strips of power. They fit on the right rails of a rack box and do not remove horizontal mounting from other equipment.

You can have either single- or tri-phase power depending on your location and type of building. Ask a licenced electrician if you're not completely sure. The difference is here:

The rate is 60 cycles per second in the United States. Single-phase power Alternates between positive and negative tension. That means that each time it moves from positive to negative and back the wave has zero voltage. Most household and office electricity are single phases, with the following types of receivers (outlets):

By offsetting three simultaneous waves, Three-phase power eliminates these zero voltage moments. The other two are positively and negatively affected when one wave reaches zero voltage. In commercial and industrial environments, three-phase power is common.

Most agencies have single-stage power – but before you purchase any new equipment, make sure you know.

The volts and amps (VA) or watts (W) in the user handbook or the equipment itself must be the power consumed by each device. Add your equipment and write down the total consumption. Your power source — a service panel's utilities power, a general energy source or a USV backup power — should be higher than that.

Note: Many devices are equipped with automatic power supplies which may be used with 120 to 240 voltages. Base your calculations on this figure when your energy is 120V (typical in North America). Use the higher number when the system is 200V/230V (typical for Europe and Asia). Use the figure on the device or its user manual for input amperage.

A PDU connected to a UPS can supply a smaller network with conditioned power. Lengthy and more complex systems may require several PDUs and a large-scale UPS system.

Probably the easiest answer to this question, but take it seriously. At least as many outlets as the number of connections you must link should be available on the PDU that you choose. Adjustment of your count if a device has more than one plug, or if one device needs to be connected to another. And don't forget to leave room for other devices like lights or fans.

Multiple devices can be supported by each PDU. The shape of the plug is the voltage and amperage required. CyberPower provides the following plug types of PDU models:
