Our Unique Turnkey Approach

Where Specialist Power Systems are different is that we can offer the complete turnkey solution to your standby power strategy, offering the entire range of products to build a complete solution.

Why not look at our other products which are often included as part of the broader standby power strategy. See our range of UPS and Emergency Lighting/Central Battery Systems.

Specialist Power Systems don't just look at the initial generator requirements. We also offer whole life support using our extensive generator service and maintenance contracts.

Often, we are placing the standby diesel generator into a much greater overall design. We take into consideration other sizing factors for equipment such as (ATS) Automatic Transfer Switch, (UPS) Uninterruptible Power Supplies and (AC) Air Conditioning.

We look at what type of loads are involved and whether they might be inductive, capacitive or reactive. By doing this we ensure overall system resilience from the outset.

How a Standby Generator Works

Backup power can be provided for short to medium periods of time using just a UPS. However, this can become costly when applications require extended runtimes.

This is when a generator solution will be more suitable due to the high capital cost of large battery banks and the need for those to be replaced at the end of their respective design life (5 or 10yr intervals).

Typically for a backup generator to work in an automated way, an Automatic Transfer Switch (ATS) is connected to the mains power, the standby generator, and the load. If the mains power should fail for any reason, the ATS sends a signal to the backup generator to start up and automatically switches the connected load from the mains supply to the emergency generator supply.

It will take approximately 10-20 seconds following a mains failure for the backup generator to re-energise the load. To keep your critical systems up and running until the emergency generator takes over, you will need a UPS to sit between the ATS and the load for a seamless transition from mains to backup generator power.

Usually, critical systems will be fed from a UPS which will provide zero break in power in the event of a mains failure with other non-essential circuits going off for a short period before being re-instated from the generator supply.

The main advantages of a generator setup are that they provide longer runtimes, have significantly lower life cycle costs versus a UPS only setup with a large battery bank and can often hold a higher residual value over a longer time period.

The Difference Between a Central Power Supply System and a UPS

A Central Power Supply System (CPSS) looks very similar to a standard UPS but has some unique features that make CPSS’s more resilient, such has higher fault clearance capability and quicker battery recharge times.

It is especially important that in a mains failure situation the inverter sizing is sufficient to clear downstream protection devices in the event of a fault.

Emergency Lighting or a CPSS is a specific type of back-up power system used with emergency and safety-related applications such as lighting, alarms, and security systems. They share many of the design and operational features of a typical online UPS but have significant differences that conform to strict Pyro ratings and regulations.

Since emergency lighting is a critical life safety installation, it is vital that a central power supply system used to power emergency lighting is designed with specific features conforming to BS EN 50171.

British Standards EN 50171 and What It Does

All Central Power Supply Systems must meet the strict criteria outlined in EN 50171 for use with essential life safety protection systems. The standard governs the below key safety features to ensure compliance.

  • Enclosures to be resistant to heat and fire
  • Battery chargers to be capable of automatically charging their batteries that have been discharged so that they can perform at least 80% of their specified duration within 12h of commencement of charge
  • Inverters shall be capable of permanently handling 120% of the load requirement for the rated duration
  • Inverters shall also be able to start the full load of a previously unpowered system, within the response time of EN 1838 in the mains failed mode
  • Batteries for central power systems shall be of a type having declared life expectancy of at least 10 years at 20°C ambient temperature
  • The battery and system design shall be capable of meeting the declared performance initially, during and at the end of the stated life

Power Distribution

Icon showing a PDU

A Power Distribution Unit (PDU) is an advanced version of an extension lead you would find in your home used to power more than one electrical device.

PDU’s are usually placed within a 19” equipment rack and are designed to distribute power to multiple devices, these are often mounted vertically at the rear (Zero U type) or horizontally in a rack (for example 1U, 2U).

PDU’s have multiple outlets and can be made up of many different socket types to suit any specific requirement. They also come in single and three phase options and various power ratings from single phase 10 amp right through to 3 phase 32 amp typically.

There are many different PDU form factors and levels of sophistication and on this page, we try to explain the benefits of each type. Here is a quick overview of the different products we offer but please read on for full details of our PDU products.

  • Basic
  • Metered
  • Monitored
  • Switched

We cover more details about each of these products below but if you would rather speak to one of our experts, call us today on 01234 851155 or email us at [email protected] to discuss your PDU requirements.

Basic Rack PDU

Basic PDUs provide reliable power distribution to critical IT equipment within a rack or cabinet which are low-cost entry-level strip solutions with no intelligence.

They meet a broad range of applications with almost unlimited different configurations available, typically providing a single input with multiple output receptacles in various socket types 3 pin UK plug, C13 10A and C19 16A and in both single and three phase versions.

Metered Rack PDU

Metered PDUs allow users to view power consumption data instantly from a local display which is ideal when deploying or moving equipment to monitor power usage and prevent overloads.

A metered PDU is normally best suited for environments where seeing basic information at the rack position is deemed sufficient.

Some models will show power by socket and some will only provide the power of a branch of circuits so careful consideration is needed when specifying this option.

Metered rack PDU icon from Specialist Power
Monitored rack PDU icon from Specialist Power

Monitored Rack PDU

Monitored PDUs provide a comprehensive view of power usage, both at the rack and via remote access typically via the client’s local area network. Monitored PDU's are available in socket-level and branch-level remote monitoring options depending on the requirements and level of sophistication required.

Monitored version offer quick access to critical information to evaluate energy usage trends as well as provide alarming capabilities to alert users of breaches in user-defined power thresholds. They are recommended for high-density data centres that want to monitor or improve power usage effectiveness (PUE).

Switched Rack PDU

Switched PDU's provide a comprehensive view of critical IT equipment power usage, both at the rack and via remote access with the added ability to remotely turn on, turn off, or reboot power at each outlet.

Switched PDU's also tend to provide all power monitoring benefits of the metred and monitored types but in addition have the capability to remotely control each socket.

They are extremely useful for data centres that require a quick and easy way to power cycle equipment in a large facility or, in some cases, an entire network of facilities. These are the PDU’s of choice for unmanned sites generally.
