External power supplies convert ac power from a wall outlet into a lower voltage, we stock a large range of external power supplies these can be anything from desktop switch mode power supply, interchangeable power supply, fixed plug ac/dc switch mode power supply, lugged power supply to ac/ac linear power supply. All Ideal Power units are fully ErP II compliant. The external interchangeable PSU range from Ideal Power can include the following approvals: UL, cUL, TUV, RCM (C-Tick), CB, LPS, CE, FCC, ErP II, CEC-V, RoHS II, REACH. (Other approvals such as CCC, PSE and KC are available on some models, please contact us). For further information regarding approvals and standards relevant to power supplies, view the standards conformity page. If you know what you are looking for click here to find your product with the help of our product selector or read more about the types of different external power supplies. Alternatively please free to contact us if you would like help finding the right power supply. The external interchangeable PSU range from Ideal Power further improves the versatility of external PSUs by allowing multifunctional use as either a desk-top or a plugtop PSU in one unit. Switch Mode Power Supplies With the limitations of linear power supplies, you might think using a switch mode power supply would make more sense, especially given that they are a smaller, lighter and more efficient choice. However, the challenge lies in the noise and ripple performance. AC/DC Power Supplies often produce variable frequencies together with output power, rather than the static frequencies linear PSU’s work at (Though they can be manipulated to operate at a fixed frequency, these models are specially manufactured for audio applications). This is not to say that standard switch mode PSU should be written off at all, as there is still a lot of scope for audio PSU within this range. Linear Power Supplies Linear power supplies are often a quick and economical fix in the audio industry and work particularly well with products such as amplifiers. This is because AC/AC power supplies possess a low operating frequency, producing optimal noise and ripple performance. However, the size and weight of linear power solutions increase with the power they produce; which results in limitations on the output power of linear power supplies. The technology used in linear PSU also means they are rarely as efficient as their switch mode counterparts. At ideal Power, we can offer AC/AC power supplies ranging from 6 Watts to 40 Watts, with a proportion of units conforming to ErP II (Level 5) efficiency (up to approx. 16VA), or even Level VI efficiency standards in some instances.
Variety of easy-fit AC Plugs (Pins)
A simplified purchase solution for procurement professionals by offering the four most popular AC Plugs covering UK, European, United States (North America) and Australian mains-input types. This means the external power supply unit can be instantly converted to operate in another part of the world by simply sliding in a different AC plug type. Alternatively, any of the external interchangeable PSU range can be supplied with a single designated AC plug type which assists with budget targets.
Ensure maximum compatibility with an optional 8-way set of DC connectors
The polarity of the DC connectors can be changed by alternating the position on the output lead. This allows the PSU to be used in both centre positive or centre negative configuration.
