Input filters or 12 pulse rectifiers?
With current recommendations demanding lower levels of input harmonics (THDi) it is more common for larger systems to require some form of input filtering to achieve this. Twelve pulse rectifiers can improve upon more standard 6 pulse systems and offer the ability to correct the problem across the whole load range. Passive input filters added to 6 pulse designs are usually cost effective and improve the input power factor, but often only effective at higher load levels of the load, typically...

What is ECO mode?
ECO mode is often referred to as 'Active Standby' and is mainly used on sites where the general mains supply is relatively stable or the load is not senstive to mains interference. The UPS runs in bypass for normal conditions and transfers the load, without break, to inverter when the mains fails. This configuration is available on our entire UPS range upon request. This mode provides an improved system efficiency of around 98%.

What is a Static Inverter?
A static inverter is virtually the same as a UPS system except they are configured to operate in 'active standby' mode with the bypass supplying the load during normal conditions. 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...

What does Autonomy mean?
The battery duration at a specified load level is referred to as the battery “autonomy”. A UPS battery can be sized to support loads from a few minutes up to several hours, however the cost of a large battery at a high load level can sometimes mean that a Diesel Generator should be considered. Increasing the ‘autonomy’ is achieved by adding extra battery strings connected in parallel, however it is important that the charging capability of the UPS system is considered.

What is a 10 years battery?
10 years is the generic term given to high integrity batteries that fully comply with IEC60896-2 in terms of construction, performance and design life. Usually costing slightly more than standard sealed lead acid products, they offer 10-12 year design life, threaded copper insert terminals, flame retardent case material (UL94-VO) and are generally selected for premium installations such as Hospitals and Telecommunications.

What does the 'Design Life' of a battery mean?
Battery quality can be determined by the ‘design life’, typically between 5-12 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. From experience, we generally expect a good quality 9-10 year design life product to need replacement in approx 6-8 years.

What is a Temperature Compensated Charger?
Variations in ambient temperature presents the greatest threat to battery installations. Special circuitry can be incorporated in the UPS to compenstate for any variations in the ambient temperature making the recharge voltage temperature dependant - the higher the temeperature - the lower the recharge voltage. This feature ensures optimum battery performance and helps to prolong their life.
