Manufacturing Overview
The Powerstar voltage optimisation systems are designed and manufactured by EMSc (UK) Ltd in the UK using locally sourced components wherever feasible.They are manufactured to BS171-IEC60076-IEC60726, using low loss core steel, close coupled copper and high quality components.
Powerstar operates at ambient temperature plus a maximum 5 degrees celcius. (ie. if ambient is 20 degrees celcius, the Powerstar temperature will be between 20 degress celcius and 25 degrees celcius.)
The Powerstar unit has a design life in excess of 50 years for the wound components; also it has been designed so that over 98% is recyclable.
Efficiency under various loads
Voltage optimisation works best on inductive loads - motors and lighting for example - and significant savings can be achieved on motors in particular, especially if these are not loaded at 100% of their capacity for 100% of the time.
All Powerstar systems are fully tested under BS171 and these tests include:
- 25,000V surge/transient protection
- 50,000A fault level tests
- Efficiency tests at 25%, 50%, 75% and 100% loading
- Impendence testing
- Overloading test at 100% of the Powerstar capacity for 4 hours
