Regulated AC to DC Adapters

ac dc adapters

Regulated AC to DC Adapters available from NTE Electronics, Inc.

These AC-DC switching power supplies constantly supply a steady, regulated voltage in any situation, as opposed to non-regulated AC to DC Adapters which have a tendency to vary widely in voltage.

Available in 5V, 6V, 9V, 12V, 18V and 24V outputs and a variety of wattages from 2.5W to 72W, with output currents from 500mA to 6A.

Now available are two Universal AC-DC regulated adapters. These Level VI Efficiency Standard Compliant power supplies are available in 1A (15W) and 2.5A (30W), have switchable, multi-voltge outputs ranging from 3V to 15V, and inclues 2 reversible polarity tips. In addition to our fixed output adapters, we're sure you will find the right device for your application.

Also available are:

Features include:

  • 100 - 240VAC, 50/60Hz Input
  • Available in Wall Mount & Desk Top types

Choosing the Right AC Adapter

Inspect the device and look for any labels or symbols that indicate either the voltage or mAh/A, if not, check the user manual or do a quick Google search.

Important symbols to look for are:

  • V = An input Voltage for example 12V
  • AC or DC – as indicated by a symbol.
  • mAh/A – current consumption

Choose the right specs by matching the V and equal or beat the mAh, so if you are choosing an AC adapter, make sure you check the following:

  • The adapter output V matches the rated input V of the device
  • The adapter output is greater or equal to the devices rated mAh or A
  • The plug fits into your device and has the correct polarity

Usually, all of this info is on the adapter sticker, remember you are always looking for the output V and mAh or A.

Once you have the V and A determined, most appliances will have a circular connector with the inside hole carrying one pole and the outside carrying the other.

The most common is center positive (+) connectors.

There is also the less popular center negative (-) connector.
