Meanwell or Mean Well has been producing high quality, low cost, power supplies for nearly 30 years. They produce a large range of Power Supply Units, adapters, Chargers, DC DC Converters and DC AC Power Inverters, all to the highest ISO9001 standards.Their main factory in Taiwan is highly regarded in the switching power supply market throughout the whole world producing well over 2000 different models across their range.Simply Power Supply has access to the whole range of Meanwell power supplie....

Linear Power Supplies are far less common than Switch Mode Power Supplies. This is partially due to the much lower production costs of the latter, but also Linear units are bulkier and heavier too.In general the type of Linear unit which we would be concerned with would be Linear Regulated PSUs, this is because if the output is not regulated it will change with the size of load and input variationsThe one major benefit of using a Linear is the much lower ripple and noise in the output DC. This i....

A Kilowatt is a unit of measurement of power and in our case electrical power. A Kilowatt is actually one thousand Watts.The Watt was named after the Scientist James Watt after his ground breaking work on the development of the steam engine and it was formally adopted as the SI unit for power in 1960, although it was widely used before this.In the case of electrical power a Watt is the voltage multiplied by the current, therefore we get the equation:W = V x IIf we are discussing the power of a D....

The output jack on an adaptor or desktop power supply is the part which is hardest to define for a citomer over the phone.It is very easy to work out the voltage and current you would need to replace a failed power adaptor, however when it comes to the size and type of output jack there is almost always some confusion.With this in mid what do you need to know? Firstly it would be useful to know the polarity of the jack, most are Centre Positive (C+ve) which means that the inside of the jack carr....

A power supply is often described as galvanically isolated and this manes that there is no direct path for the flow of current from the input stage to the output stage, this is a safety feature which is there to protect the load. It also means that the ground reference on the output can be different from that of the input, this is often refered to a floating ground and allows for power supply units to have their outputs wired in such a way as to give either a positive or negative output voltage.....

Grid Connect (or Grid Tie) inverters are DC to AC inverters which are able to export the ac power which they produce to the grid.The basic idea is that you produce DC via solar panels (PV) or a wind turbine and then you push this through the inverter and out to the grid. For this electricity you produce you will be paid by the energy company, based upon a contract which has previously been signed.In order to do this in the UK you need for the inverter to comply with (amongst other regualtions) t....

Frequency here refers the the frequency of AC electricity and typically these are either 50Hz (UK Mains), 60Hz (US Mains) and 400Hz (used by many aircraft).The term Hz means Hertz and is named after Heinrich Hertz and it is the designated SI unit for frequency. The ferequency is the number of cycles per second.The main issues which are presented by the different frequencies required either by different countries or industries is the fact that certain types of electrical equipment either will not....

Electricity comes in two main forms which are Alternating Current (AC) and Direct Current (DC).AC is what is distributed by the national grid and is so called because the "direction" of the current changes - through zero - every 50 seconds (or 60 seconds depending on where you live).In general DC power is the type of power which we deal with at Simply Power Supply. Most indutrial controls and processes will employ a DC voltage, often 12Vdc or 24Vdc, and almost all telecoms systems work....

The term Desktop Power Supply can be confusing as this is often what the ATX type power supplies found in desktop computers.I this case we are discussing small enclosed power supplies which are either line in and out or have an IEC inpt with a line out. These are also sometimes refered to as Lump in Line or destop adaptors.Generally these units are used in applications where the power supply is esposed and often in IT situations (for example to run a printer or monitor) and the unit is therefore....

Chassis Power Supplies or Chassis Mount Power Supplies are used in a variety of applicaitons and are very basic in style. They are often called enclosed power supplies because the internal electronics are enclosed by a case (which is often vented too).The case will have a series of threaded holes for fixing it to a base plate or other mount in order to hold the unit in place within the panel, instrument or machine which it is housed.Simply Power Supply has a very wide range of units from 5vdc to....

Battery chargers are part of our core range at Simply Power Supplies. In the main we offer chargers for lead-acid (or sealed lead-acid) batteries, although we are able to offer solutions for a range of other batteries.There are a few things whihc you will need to know before you buy a battery charger, the first is obviosly what voltage you need. Normally you will select one by the nominal voltage of the batteries which you are charging, this can be 12v, 24v, 36v, 60v, 110v or even 220v, although....

The unit of measurement Amp is short for Ampere and is the measurement of electrical current.It is the way in which we measure electrical charge passing any given point in an electrical circuit, in many ways we can think of this measurement as a flow rate (think about flow of water through a pipe).When thinking about a power supply you will often have two of three very important pieces of information, the Voltage, Power or Current which you need. These three units of measurement are linked throu....

Over the next few months we will be trying to cover some of the (sometimes) confusing terms which seem to crop up when discussing Power Supplies and DC Power in general. We will start with A and see where it take us.Keep checking back for more!A is for AmpsB is for Battery ChargersC is for Chassis Power SupplyD is for Desktop Power SupplyE is for Electricity
