2009
The start of 2009 has seen several product developments with the introduction of our new high performance Sirius P range from 100 to 250kVA as well as a re-designed higher power version of our cost effective Power Dialog range from 5 to 10kVA. CPS has also launched a Central Battery System (CBS) range designed for emergency applications and compliant to key elements of EN50171.

2008
With increasing stock and staff levels the company moved to a larger premises in 2008. Warehouse space more than doubled and an open planned office enabled all internal functions to be operated on a single floor improving departmental communication. The new premises also has the added benefit of a dedicated room for customers that is now home to several of our UPS units providing the opportunity for hands-on demonstratons and training. This led CPS to developement it's own official CPD presentation entitled "Static UPS Principles and Selection Criteria". This year has also seen our Starlet M series developed to include 30 and 40kVA designs.

2007
2007 has seen many product developments allowing our rack based Dialog Dual range to extend up to 10kVA, the new Hyperion range extended downwards to include 100, 125 and 160kVA models as well as the introduction of the new high performance Starlet M series.

2006
During 2006, CPS became an integral part of an international manufacturing group enhancing access to a wider range of established transformerless UPS designs with the option of active filtering and advanced communication facilities. CPS have also introduced the new highly competitive Hyperion range from 200 to 300kVA which incorporates a power factor corrected rectifier for low THDi and excellent performance.

2005
Since the beginning of 2005, CPS has seen greater expansion into the ‘total power solution’ having installed a 900kVA Generator and switchgear, 700kVA generator complete with switchgear and cabling, plus a turnkey supply of 500kVA generator, 200kVA UPS and all associated switchboards for distribution and auto changeover.
This year has also seen CPS consolidate their position as a major UPS supplier to Hospital and Health Authorities throughout the UK working with specialised partners to fullfil the increasing need for secure isolated power systems in today’s NHS Hospitals.

2004
In the early part of 2004 CPS launched the new website containing many more pages with improved content about our products and services. Improvements are now being made regularly ensuring that specs, news and products are kept up to date. This year also saw CPS successfully complete two significant combined UPS/Generator projects consisting of a 275kVA Genset with a 100kVA UPS module and a 400kVA Genset with
2 off 200kVA UPS modules. Due to the increasing workload throughout this year CPS invested in it’s staff by adding two new engineers to the service team, designating a permanent contracts engineer and employing an in-house sales support engineer.

2003
In 2003 CPS appointed an exclusive agent to represent business interests in Scotland.

1997
During 1997, the company acquired the adjacent premises with a view to expanding the warehouse operation and storage capacity. This extra space also enabled CPS to bring CAD capabilities back in house. The extra test facilities now mean that customer witness testing could be carried out without disturbing normal test programs
and heat run requirements. This year also saw CPS secure it’s first combined UPS/Generator order.

1995-96
In 1995 CPS invested in a new Italian manufacturing plant through R&D and shareholding. Early 1996 saw the introduction of the Planet UPS with an initial model range from 10kVA to 125kVA. The range proved to be extremely successful, a completely new design, researched and developed by CPS and our European partners. Minor facelifts and enhancements have enabled us to ensure these products stay at the forefront of technology with the extension of the range up to 500kVA.

1990
The premises in Hitchin virtually doubled in size during 1990, to further benefit customers with an extended test area and training facilities.

1988-89
Constant Power Services Ltd was originally formed in the late 1980’s to provide a reliable source of service support and engineering expertise in the field of uninterruptible power supplies and power conditioning.

The company initially commenced trading near Peterborough, but at the end of 1989 it acquired it’s own premises in Hitchin to ensure that stock levels and spares could be increased to support an expanding customer base.
