WARNING: Some 'cheap' switch-mode power supplies are entering the Australian market, many of them will not provide the current output stated CONTINUOUSLY and must be derated especially at high temperature (i.e. Australian conditions). We recommend you use a 'quality' power supply like the Manson or Meanwell. Click here for more info. All Manson power supplies have a 1 year warranty and all Meanwell power supplies have a 2 or 3 year warranty.

Operational tips:
1. Carefully check the voltage of your appliance before connecting and DO NOT switch on until you have checked the following: (a) Check current requirement (the power supply should always have more current output than the device requires). (b) check the connection required (e.g. the plug type) and (c) the polarity. i.e. positive or negative connections.
2. Note, unregulated power supplies have a higher voltage when no load is drawn...if your device is sensitive try using a lower voltage setting or purchase a regulated supply. Also a regulated supply is better for audio equipment because the unregulated supplies often produce 'hum' in the speakers. A linear power supply should be used when AM (Amplitude Modulated) radio equipment is used. i.e. avoid using Switch Mode Power Supplies (SMPS) with AM.
3. With the high-current SPS power supplies we have been advised that, if drawing more than 10 Amps continuously, you should ensure that proper lugs are used and the terminals are tightened securely. If operating continuously at high current we recommend using the SPS9600 60A supply which has HUGE terminals at the rear and remote sensing that compensations for the voltage drop in cables!
4. All Manson switch-mode power supplies have proven to be very reliable and only TWO have been returned faulty to date. All come with 12 months manufacturer's warranty. Manson engineers tell me that the biggest problem they have with the SPS range is with people trying to charge batteries but connecting them with reverse polarity! Please TAKE CARE and ask us for instructions.
5. The SPS8400, SPS9400 and SPS9402 have an internal variable resistor that can be adjusted for a fixed output between 11 and 16 Volts (factory set to 13.8V). Please ask for further information and ensure that only qualified personnel are allowed to open these power supplies (extremely dangerous voltages inside).
6. All SPS power supplies can now be used in series for higher voltage (the terminals are floating or isolated) provided that an external diode is used to protect the supply from reverse voltages! NOTE old versions of the SPS8400 were negative earthed!
7. Another application for the SPS8400 power supply is to replace a 12V car battery when recharging lithium-ion or polymer battery packs and NiMH battery packs as these chargers require high current. Obviously up to ten (more with the SPS9600) such chargers could be connected to the one supply. Take note, model car, aeroplane or helicopter enthusiasts and clubs!
Some suppliers of 'cheap' switch-mode power supplies say their units have a 10% voltage tolerance compared to 2% (maximum 5% on some low voltage units) for Meanwell. I suspect that the 10% is referring to the voltage adjustment range (who knows as they don't provide a data sheet).
Whichever it is, wouldn't you prefer to purchase your power supplies from someone who is ISO rated and knows what they are talking about and can provide reliable and complete specifications and technical backup?
Always check any power supply that is used as a desk-top unit. Are the ventilation holes big enough to insert a screw driver or other metal object? Can you see the components inside? Are the mains power connections properly insulated inside? These units are clearly a safety hazard!
UPDATE: Regarding some 'low-cost', 'no-name' switch mode plug packs and in-line or laptop style power supplies. One has just been returned (which we no longer sell) with the components inside melted due to high temperatures. Some of these 'cheap' plug packs have a maximum temperature of 35°C (for Australian conditions?), a voltage tolerance of +/-8% and MTBF (Mean Time Between Failure) of only 30,000 Hours!
It's hard to even get this data from 'no-name' manufacturers or 'who knows where they're manufactured' suppliers but Meanwell provide the most comprehensive data you'll find!
The Meanwell plug packs have an upper temperature limit of 50 to 60°C (with current derating)*, a voltage tolerance of +/-5% (down to 2% for higher voltages) and a MTBF of up to 711,000 hours.
e.g. The Meanwell high power 120W in-line power supply (AS-120P) has OTP (Over Temperature Protection), active PFC (Power Factor Correction), a fully enclosed plastic case (spill a cup of coffee on a 'cheap' unit and watch the sparks fly) and a life expectancy of 6 years (operating 12 hours/day at 70% load).
AND, as with most Meanwell adapters, it uses an IEC320-C14 3 pole mains inlet with removable lead (that's the same power lead used on most computers) which allows it to be replaced easily if damaged or if using it overseas!
So ... which make of power supply will you buy?
FURTHER UPDATE: I have just examined a Taiwanese made desktop power supply (Avair) sold by a major electronics distributor in Australia and found the following:
1. Although it has some 'interesting' features and was very compact in design it looked cheap!
2. The negative of the DC output was connected to Earth (no mention of this in the manual) - meaning that it cannot be used in positive earthed or series operation.
3. The manual was poor especially the 'specifications' with the ripple being given for 'rated load' only and not 'worse case' (which I found to be 2 to 3 times higher). The temperature of operation was given for the internal 'heatsink' and not, what is normal, the ambient temperature!
4. Poor quality high-voltage electrolytics are used inside, no silcon or glue is used on large components that often move (vibrate) causing cracking of solder joints. As for the design, I noticed there were no ceramic capacitors on the output terminals (this would increase ripple) and I particularly noticed two high voltage bridge rectifiers connected in parallel?!?!?
5. Ventilation holes were completely open and the 240VAC connections inside were openly exposed.
6. The Earth connection was through the PCB rather than using a regulation thickness wire to the outside metal case.
7. The high voltage and low voltage circuits were 1-2mm apart on the PCB, but worse was the high and low voltage heatsinks that were connected together to provide extra heatsinking capability in this 'compact' design. This means that the high and low voltage circuits were only separated by the thin insulator used on the semiconductor devices!
8. It had no Australian approval and the only international approval it 'appeared to have' was CE (printed on the unit). No mention of CE is printed in the manual and no mention of the actual approvals (EN numbers) is given!
What is MEPS?
MEPS (Minimum Energy Performance Standards) is a mandatory ANZ Government initiative effective from December 1 2008 (implementation date in Australia), to eliminate low efficiency external power supplies from the market and encourage the use of high efficiency power supplies (performance mark IV). Many of the existing plug packs on the market today will not comply with the new AS/NZS 4665-2005 standards.
