Uninterruptible Power Supplies   UPS Options -----------------------------------------------------------------------------------------------------------------------------------------     500va to 10kVA Comms rack and tower UPS models for small sized applications >   UPS Batteries The battery can be seen as the ‘heart’ of the system, it is often the most expensive item with absolute reliability demanded. CPS believe that just as much consideration should be given to the battery as the UPS itself. Batteries can be split into two types, ‘Open-vented’ and Sealed/Valve regulated lead acid (VRLA). Generally, the VRLA types are the battery choice for modern UPS systems as they require low routine maintenance, are environmentally friendly and are usually a more cost effective solution. Battery quality can be determined by the ‘design life’, typically between 8-12 years for VRLA batteries. The ‘design life’ is not and never will be a guaranteed life expectancy and relies on several factors including environment, temperature, maintenance, number of discharge cycles, charging regime etc. Battery & UPS Disposal Constant Power Services Ltd are experienced in the replacement and disposal of UPS and batteries in accordance with the ‘Special Waste Regulations 1996’. CPS hold a waste carrier license and only use approved waste disposal agents. All our batteries are ‘non-hazardous valve regulated sealed lead acid’. Battery Housing Integral Our UPS range offers the option of integral battery accommodation up to and including the 30kVA UPS module. Both the Starlet M & Vega can accommodate batteries in the bottom half of the enclosure and the Planet a single battery string on the right hand side of the UPS enclosure. Open Racks (Drawing) Free standing structures, complete with acid resistant adjustable feet with anti-shock options for offshore or unpredictable environments and anti-seismic options for areas of geological unpredictability or sites such as nuclear power stations. All units designed to provide optimum access for installation and maintenance for the respective battery block type. Provides flexible designs to optimise plant room space and structural limitations. Cladded Racks (Drawing) Enclosed structures designed to provide a cost effective alternative to battery cubicles. Based on open rack type with surrounding panels and raised cover. Provides features such as required venting, matching of BS4800 and RAL colour schemes and the ability to fulfil specific requirements such as IP ratings. Provides flexible designs to optimise plant room space and structural limitations. External Maintenance Bypass Panel The provision of an External Manual Bypass Switch (MBS) gives the ability to fully isolate the UPS enabling maintenance, upgrades or system removal without disturbance to the load. The switchgear meets the electrical regulations for local isolation and allows all AC cabling to be completed even before the UPS is delivered to site. This enables delivery, switchover and commissioning to be performed on a clean site during normal working hours, thereby keeping costs to a minimum and reducing the risk of exposing the UPS to building debris and dust by being installed too early. -------------------------------------------   Modular UPS 30, 60 & 120kVA three phase scalable comms room UPS range > -------------------------------------------   10 to 800kVA Versatile floor standing modules for IT & Industrial applications > Service Agreements 24-7 callout, preventative maintenance, spare parts   Delivery & Associated Services ------------------------------------------- Site Surveys and Pre Sales ------------------------------------------- Low Voltage Switchgear  ------------------------------------------- Diesel Generator Sets ------------------------------------------- Central Battery Systems ------------------------------------------- UPS Network Monitoring   Isolation Transformers An Isolation transformer, housed in a separate floor standing sheet steel ventilated enclosure, provides the opportunity to earth the UPS output neutral thereby eliminating the potentially dangerous effects of four pole switching upstream of the UPS. This unit can also be used to feed the input of a transformer-less UPS system to accommodate two separate feeds from different sources. Active Filtering (Vega UPS option only) The Vega UPS range can be equipped with an Active Filter to provide a very low input harmonic distortion (THDi) of less than 5% and an input power factor of 0.99 to dramitically reduce running costs and meet the more demanding specifications. This option is fitted integrally, therfore has no effect on dimensions and only increases weight by approx 5kgs. Active Standby Mode for Emergency Lighting All our UPS systems can be configured to operate in 'active standby' mode. This term means the bypass would supply the load during normal conditions and when a mains failure occurs contactors are used to transfer to inverter with the standby batteries then supporting the load (typically for 1 hour or 3 hours depending on application). This type of product is generally used in emergency lighting applications, offering efficient backup with reduced running costs, although provides no filtering or protection for more sensitive loads such as computer equipment. This type of operation is a simple configuration on the Vega, Starlet M and Sirius products, howeveron the Plant and Hyperion range this is a factory fitted option. Top Entry Cable Chambers (factory fitted option) Units from 100kVA can be supplied with an optional chamber to allow easy access for top entry cabling. These matching sections incorporate an aluminium gland plate as standard, however they can also be supplied with copper busbar connections for the rectifier, battery, bypass input and UPS output. Steel Plinths Fabricated steel stuctures can be manufactured to support your UPS and batteries up to a raised floor level or to simply enable bottom cable entry on larger UPS installations. Gland plates and angles to support floor tiles can also be incorporated into design as well as adjustable feet or shims. Please note our plinths are designed and manufactured to suit equipment and specific site requirements. Temperature Compensated Charger Typically for areas where fluctuations in the ambient temperature common and the risk of exposing sensitive battery installations to high temperatures is a possibility. CPS can minimise the effects of this problem by incorporating temperature sensing and specialised control circuitry in the UPS module to automatically adjust the battery float voltage, thereby eliminating the chance of plate distortion or gassing often associated with high temperatures. Remote Monitoring A range of wall mounted remote panels are available as well as network and environmental options allowing web-browser monitoring, emails, SMS and safe unattended server shutdown. More details are available on our remote panel and network monitoring pages Fan Failure alarm (factory fitted option) Units from 100kVA can be fitted with a device for monitoring the operation of each individual fan. In the event of a fault, an alarm shows on the front panel of the system via relay contacts and software. Parallel Operation PCB For additional capacity or increased system integrity it is possible to utilize a simple ‘plug and play’ paralleling card which allows easy adaptation from a single module to a parallel module, typically available up to 6 units. UPS Group Synchroniser (UGS) (Sirius & Sirius P UPS only) Our Sirius and Sirius P UPS ranges can be used with a UGS control system that ensures multiple UPS modules provide a synchronised output in all conditions. System incorporates a UPS interafce slot card and a wall mounted control panel. © Copyright Constant Power Services Ltd Part of the Riello Elettronica Group Italy
