What is Voltage Optimisation?
Voltage optimisation is a generic term given to the managed
reduction of voltages received from a supplier down to a value
that more closely meets the designed rating for all your electrical
appliances.
Electrical appliances manufactured for the UK and Europe are
rated at 230V, reducing the voltage towards this level can lead
to;
• Lower energy consumption
• Reduced carbon emissions
• Extended lifespan of electrical equipment
• Lower operating temperatures
Meters charge us for kW/h used. An appliance at 2400 watts and at 240
volts will use 10 amps of current.
Watts=Volts x Current, so by using Ohms law V/I x R, the resistance
would be 24 ohms.
Current is proportional to Voltage, so at 220 volts, resistance is fixed
at 24 ohms so current is 220/24 = 9.2amps. Power consumed is now:
220 x 9.2 = 2024 watts, a saving of 376 watts

What equipment benefits most
from voltage optimisation?
•Lighting
SON – Metal Halide – Fluorescent Tubes – Tungsten – Halogen
•None Thermostatically Controlled Heating
Towel Rails – Hand driers – Hair Driers – Over Door Heaters (Air Curtains) –
Electric Showers
•Fixed Speed Motors
Refrigeration – Air Conditioning – Pumps – Fans
• White Goods
Microwaves – Fridges – Freezers – Washing Machines - Dishwashers
Equipment Protection
Voltage Optimisation ensures electrical appliances operate closer
to their optimum design condition, this can help prevent
excessive heat build up often caused by over voltage. Therefore,
protects electrical goods from premature failure often cased by
over voltage.

• Light weight and compact with simple wire in wire out connection
allows for ease of installation.
• 8 hour continuous operation fully rated transformers
• Product range from 60 amp single phase through to 400 amp three
phase units
• All models with Over Current and Over Temperature Protection as
Standard
• Under voltage protection (intelligent units only)
• Direct PV connection (PV connect units only)
• Designed and manufactured in the UK
Simple Installation
All matt:e units are very simple to install with simple wire in wire
out connections on all models.
Saving on time and costs during installation.
B60 Single Phase
B100 Three Phase
Robust design. Built to last.
All matt:e Voltage Optimisers are designed to cope with
100% of the load 100% of the time.
Without any moving parts or delicate switch gear, matt:e voltage
optimisers are built to last , with a life expectancy of 25 years.
Giving total peace of mind and ensuring the maximum return on
your investment
All matt:e products have a standard 5 years parts warranty
Single Phase Voltage Optimisers
Voltage Optimisation and Solar PV
Get more usable power form your PV
installation
Solar PV systems have to increase the supplied voltage to enable them to export
their generated electricity back onto the National Grid, inevitably the voltage into
your property will also increase.
Installing a voltage optimiser alongside your PV system prevents this precious
generated energy from being wasted due to inefficiencies caused by over voltage at
appliances. Potentially leaving more of the “Free energy” available for use around
the property helping to speed up the return on investment.
An example, if you are generating 3kW of power from your Solar PV System, a 3kW
kettle operating at 250V will consume additional 250W. This is additional power
that you will have to buy from the grid, by optimising the voltage your kettle could
be boiled from the power generated by your Solar System.
Three Phase Voltage Optimsers
As all site and applications are different matt:e designs and builds the Three phase
voltage optimisers to suit your exact requirements. From 60amp through to 400 amp
per phase with fixed voltage reduction of 10V, 15V, 20V and 25V.
Toroidal Transformers
matt:e uses our own Toroidal type
Transformer that is more efficient
and runs cooler than in-efficient
Laminated type transformers.
Standard Product Features
• Mains switch
• MCCB over current protection
• Over temperature protection
Optional Extras
• Manual bypass switch
• Metering monitoring Solutions
Remember …
• 220 is plenty. Most appliances are optimal at 220V
• You pay for over supply
• Typically 10 – 20% of annual billing as a saving
(dependant on loads)
A quote from the electrical guide to the 17th Edition of the IEE Wiring Regulations (BS
7671): 2008 and Part P of the Building Regulations by John Whitfield
“Since the present supply voltages on the UK lie within the acceptable spread of
values, supply companies in the UK have not reduced their voltages from 240V.
This is hardly surprising, because such action would immediately reduce the
energy use by customers (and the income of the Companies) by more than 8%”
