What is Mini Sun Power Saver (MSPS) ?

Mini Sun Marketing offers reliability and functionality through a range of energy efficiency systems that can meet the needs of an organisation.

Mini Sun Power Saver (MSPS) uses advanced German electrical technology to regulate your current supply and stabilizes the voltage, thus optimising electrical consumption in electrical appliances and machineries in residential, commercial or industrial facilities. Simultaneously, it improves the “power factor” of your electrical supply and minimizes energy wastage in equipments that may be old, faulty or of inferior quality. MSPS combines the following technologies:

• Power factor correction

• Surge and spike protection

• Noise filtration

These technologies provide several benefits:

• System efficiency

• Protection of equipment

• Savings of energy and money

How do MSPS units work?

They provide power factor correction through can-type capacitors. They provide surge and spike protection from capacitors. They provide noise filtration through a standard RLC filtration circuit.

How many units will I need?

The number of units required are primarily based on the average kVAR consumed by a facility. However, in some cases, installation of MSPS units are solely based on the requirement for surge protection. Please contact us for more information.

What benefits will I get from MSPS units?

You will reduce energy costs, protect equipment and machinery, and improve the quality of electric power coming into your facility. You will also increase system capacity; lower utility bills; achieve lower operating temperatures, longer equipment life, and enhanced equipment operation.

Tell me more about the consoles themselves

MSPS units are:

PSB & SIRIM tested
No moving parts
Maintenance free
Moisture proof, tamperproof, and dustproof
Connected in parallel, typically to a circuit panel or motor control center

What does "in parallel" mean?

Units connected "in parallel" means that the electricity flows into our unit and your load simultaneously, as opposed to "in series", in which the electricity would flow through our unit to get to your load. In parallel means that despite whatever happens to our unit, your load will still have electricity applied to it.

What are demand charges?

Utilities charge for total monthly electrical consumption by charging for each kilowatt-hour. However, they also charge for the rate at which electricity is consumed. A customer who uses 1000 kilowatt-hours evenly at a steady rate all month requires a certain size meter, transformer, and cabling to support that use. A customer who uses the same 1000 kilowatt-hours, but all on the same day, requires a bigger and more expensive distribution network for service. The utilities recover these additional costs by requiring customers to pay a demand charge, based on the highest hourly-rate of energy consumption during the month.

How does MSPS reduce kWh consumption?

MSPS  units reduce kWh consumption through the following mechanisms:

Reducing I2R losses, or line losses
Reducing in-rush power going into a motor during startup
Increasing overall efficiency

What is Power Factor?

Power Factor is the ratio of the useful power (kW) to the total power (kVA). This is a measurement of how efficient your electricity usage is. The higher the power factor, the higher the ratio between useful power and total power, and the more efficient the system is.

What are harmonics?

Harmonics are a form of noise, produced in frequencies which are a multiple of the basic 60 cycle sine wave. They are caused by switching power supplies and in other sophisticated machines, including computers and variable frequency drives. Harmonics can distort the basic sine wave, as well as cause high currents on the neutral and ground wires in a system.

What does MSPS do about harmonics?

Harmonics are complicated and each system is very individualized so there is no easy answer. In most systems, harmonics are not a problem and the introduction of MSPS units doesn't change that. In some systems with harmonics problems, the addition of MSPS units can create a resonant frequency in the circuit that makes harmonics worse.

In other units with harmonics problems, the existing harmonics are attracted to the SES unit (and away from other system loads) because MSPS represents the lowest impedance path to ground. In any case, if harmonics are suspected to be an issue in an application, Mini Sun Marketing will assist in the measurements to confirm that MSPS installation is suitable.

How do MSPS units save money?

MSPS units save money in four primary ways:

Through the elimination of power factor penalties on utility bills
By reduced demand charges on utility bills
By reduced kWh charges on utility bills
Through savings in facility costs, ranging from longer motor life, to lower temperatures, to increased capacity, to better machine operation

How much kWh savings will I get?

While the effect on demand and power factor can be easily calculated, the effect upon kWh consumption is highly system dependent and cannot be exactly predicted in advance. Based on many different installations, MSPS has experienced typical savings of between 10% and 30% of a given inductive load. MSPS will usually make a conservative estimate of kWh savings and confirm those savings at the time of installation.

Will I see the savings in my monthly bill?

You will usually see the 10% or 30% savings as a result of the demand and usage reduction because a typical utility bill varies 20% from month to month. Imagine your monthly checking account balance and how much it varies.

How are the units sized?

Units are sized by voltage/phase configurations and reactive power (kVAR) per unit. The number of units required in a facility is primarily determined by the average running kVAR. Contact Mini Sun Marketing for more details.

Where are the units installed?

For home usage, MSPS units can similary hooked up onto any available 3 pin power point. For industrial usage, MSPS units are installed throughout the facility or system close to large inductive loads. They are physically wired into circuit breakers or disconnects which are in turn connected to circuit breaker panels or motor control centers.

What does the utility say about the product?

Utilities like our product because it helps them reduce their costs, increase capacity, and improve power quality.
