Product overview

• Replace your batteries and multiple power supplies with this useful power supply
• Output between 1.5 and 35 voltage at up to 1A
• Easy and fun to assemble with 14 parts
• Requires a power supply with a maximum voltage of 28V (AC) and 40V (DC)

What can do with this kit?
Run almost anything off this DC power supply (manufacturer’s code K1823) with a 1.5-35V 1A output power. Control motors, circuit boards, models or really anything that needs a DC power input. Use an input power source of between 28V AC and 40V DC to run your devices. You can fit this kit onto almost any project with a 52mm x 30mm board, and it is easy to connect to as it has screw terminal connections for your output and input. With 14 parts, this kit is easy for anyone to assemble no matter their skill level.

What can I learn from this signal generator kit?
Practise soldering and learn about electronics and circuits with this signal generator kit. It uses resistors, capacitors, potentiometers and an integrated circuit (IC) chip, and will help you learn how to connect a circuit. The kit uses a LM317 regulator to give remarkable better ripple (80 dB rejection). The IC chip has a built in current limiter and thermal overload protection. A heatsink (not included) is recommended for the heat produced by the IC chip. This kit requires a soldering iron and solder, and may require wire cutters.

How easy is this kit to solder?
This is a great kit those looking to improve their soldering skills or those needing an adjustable DC power supply for a project. Putting the kit together is just the start – you may want to create an enclosure (not included) for the kit to protect the electronics. If you do so, make sure you don’t block the inputs, outputs or potentiometers and allow any heatsink (not included) to work efficiently at removing the heat from the immediate area. This kit requires a power supply with a maximum output of 28V AC or 40V AC (power supply not included).

Rated 5 out of 5 by from This little power supply is very flexible, i needed a bit more current at 13.80 volts so substituted the LM317 for an LM338T this is a 5 amp big brother of the supplied regulator, also changed the rectifier diodes for 6 amp one's the supply delivers the 3.5 amps i need now. Very good product.

Rated 5 out of 5 by from Great Little Board Used this to power a mini tv and video reciever, works great, 22vdc stepped down to 12.7vdc with a little fluctuation of about 0.1-3 vdc, stayed at 12.7vdc untill supply volts dropped to14.2vdc, then they dropped together untill minni tv turned off at about 10.3 volts dc. A little tricky to solder if your a beginner, but plenty of heat on the solder gun 40-50 watts a steady hand and some patients. easy diagram to follow and easy manual to under stand , as they say it does what it says on the tin, ps getts a little warm but an heat sheald sorts it out. 5*****

Rated 5 out of 5 by from Fantastic little supply. Stable and accurate adjustment. I used this to power four current loop ultrasonic rangefinders in parallel.

What heatsink is recommended for use with this kit

Asked by: Davidw
As Les has said, the heatsink needed depends on heat dissipation and enclosure size; he hasn't indicated how to work this out. As this is a "linear" power supply (i.e. not switching), the amount of heat generated depends upon both the current being drawn and the difference between input and output voltages. This means that, for example if the difference is only 5Vdc and 1A is being drawn, the regulator needs to dissipate only 5Watts (5V times 1A), so would only need a fairly small heatsink, however, if the input difference were 38.5V (the max input (40V) minus the min output (1.5V)), at 1A this would mean the regulator would need to dissipate 38.5W - nearly an 8-fold increase, so would need a seriously beefy heatsink, with the size implications that go along with this. Hope this explanation makes things a little clearer!

On this occasion Maplin do not stock a product that exactly meets your requirements, or indeed anything close enough to offer you as an alternative.

I'd like to build a power supply to run six Blackstar HT guitar effects pedals requiring 22v 1.1A each.  Would it be feasible to setup six of these power supply kits in one box therefore having one 240v input and six 22v 1.1A outputs?

size need a metal box to fit it in with space for an adjustable voltage pot to fit inside

Asked by: organiser
Unfortunately we would need to know the dimensions of the item once you have added the adjustable pot for us to be able to suggest a suitable.

I have a motor with a single coil flywheel generator. Output is 4.2 volts RMS A/C max, frequency is not known, amperage is 2 max. I want to obtain a DC output of 6v. Can I use a K18231A ?.

Asked by: Sandy
I am sorry but the item in question does not support use in your intended application, as it can only provide a 1 amp output not a 2 amp as yours requires.
