Amperor Lauch Their LED Voltage Stabiliser
Undoubtedly, LED light bulbs are looking to be the future of the leisure market as well as industrial lighting due to the many advantages they have over the infamous incandescent light bulbs.
1. The lifespan of LED light bulbs is estimated to be about 100,000 hours, which is around 11 years of continuous operation! Now, compare this with an incandescent light bulb that has no more than 5000 hours of life. Really, no match! So, if there’s a place at your premises that is routinely hard to access but needs lighting, you know what to do – just install an LED light bulb of adequate output and forget about replacing it for a couple of decades or even more!
2. The increased lifespan of LED light bulbs also translate into savings worth thousands of dollars on a single light point during the next couple of decades. A single LED light bulb may be costlier than a single incandescent light bulb but the true cost is in the number of replacements required in case of an incandescent light bulb.
3. Savings in terms of power consumption is a major highlight of LED light bulbs. An incandescent light bulb operates at a mere 20% efficiency while an LED light bulb operates at around 80% efficiency, i.e., an LED light bulb converts close to 80% of electrical energy into light energy compared to just 20% in case of incandescent light bulb. This, in turn, leads to handsome savings in your electricity bills if you completely transform your lighting needs from incandescent or halogens to LED.
Okay so I can see the longterm benefits from LED lighting, so how do I protect them from surges and spiking?
Introducing the Amperor ADP-70DC LED Regulator
The ADP-70DC is designed to provide a stabiliser 12 volt supply to LED lighting either it be in a Caravan, Motorhome or Boat. The typical voltage in any of these vehicles can vary from 10 volts to 15 volts depending on the state of the leisure battery, what else is being used inside the vehicle and whether the battery is being charged or not at the time
Many electronic appliances such as 12 volt LED’s are not designed for such a wide variation of input supply and cannot tolerate the level of swings in the voltage. It can be frustrating when reading a book when the lights are illuminated and then they turn off, just because a water pump is being operated. Worse still, manufactures of LED lights advise us that their LED’s are actually damaged by voltages over about 13 volts. LED’s that should last a number of decades are being severely damaged within a few months. Such is the problem that some LED manufactures are saying that their warranty is void if their LED’s are used on an unregulated 12 volt supply
The answer is to use the Amperor ADP-70DC LED regulator which will provide a regulated 12 volt output even if the input varies between 10 volts and 16 volts.
The main features of the ADP-70DC are:-
Provides a regulated 12 volt supply for safe operation of LED lighting
The regulated supply prevents damage to 12 volt LED’s due to over voltage
The regulated supply prevents premature switching off of TV’s due to low voltage
Features:-
Prevents damage to 12 volt LED’s due to over voltage
Provides stable voltage for 12 volt DC LED’s up to 70 watts
Prevents premature switching off of LED’s due to low voltage
Uses standard cigarette lighter input plug
Protects against voltage fluctuation
Over-current, short circuit and input polarity protection
Reliable and efficient
Small and lightweight (250 mg)
Dimensions 103mm(l) x 53mm(w) x 27mm(h)
CE & E4 Compliant

Replacing a Faulty Power Supply by Terry Owen from The Swift Owners Club
Please check out the below article published by Terry Owen from The Swift Owners Club regarding the Amperor MV3/180 Battery Charger

Swapping out your faulty charger for our Amperor MV4/180C Charger
Running on from our blog update on how to change the faulty charger with the Amperor MV3/180C, if you have the MV4/180C and wish to replace, please read on to find out how
1. Remove Dc terminals from housing
First remove the tab terminals from the 3-way housing using a small terminal screwdriver. the retaining tab will need to be pushed back, at the same time pull the wire from the back of the moulding. Make sure to note which cable is positive and negative. The third cable is not required and cab be taped up. This terminal is normally used to indicate on the control panel when the charger is switched on, but this feature is not provided on the MV4/180C
2. Connect terminals to MV4/180C
Connect the positive and negat ive terminals to the MV4 unit, make sure the polarity is correct. We recommend covering the terminals with an insulating sleeve or tape to stop them from shorting onto the casing of the unit
3. Modify & connect AC input cable
Firstly connect a covered junction box to cable provided with the Mv4. Next cut off the existing 3-way plug on the vehicle harness. Finally connect the Ac input cable to the other side of the junction box. The unit can now be turned on and tested

Fancy upgrading your CPS-65DC, so that it is compatible with the latest HP range of notebook?
Amperor are proud to introduce their HP adapter plug that will allow the user to upgrade their CPS-65DC so that it is compatible with the latest range of HP laptops
As the old standard barrel size of the HP range was 4.75mm outside diameter and 1.7mm inside diameter, Amperor have manufactured an adapter that simply clips onto the barrel and converts it to the new larger barrel size of 7.5mm outside diameter and 5mm inside diameter with centre pin

Using TFT 12v Flat Screens On Boats
Taken from Chris Caines @ PBA
"Before i start, please let me tell you that I am not an expert in this field, however if my experiences help, then that's great . . . . if you end up blowing yourselves up then I take no responsibility
This all came about when I decided that on my Chart Plotter, it would be a nice idea to use all latest C-Map Max Cartography and incorporate an AIS Engine in the display as well. The stumbling block was that I have a pair of Furuno Navnet 10 inch Colour Displays. Whats wrong with that? I tell you whats wrong with that . . . they are Navnet 1 and not Navnet 2 ! It seems that you can't display AIS or C-Map Max on the "old" Navnet screens
Solution . . . .buy a PC monitor or flat screen TV with PC input then buy the Seiwa Explorer 3 plotter module and then you can run the latest C-Map Max software and display real time AIS for under a grand including the Cartography. Brilliant thought yes . . and I get a 17" wide screen TV in the bargain
Most of the TFT screen monitors/TV's sold today are 12v, so you may think the simple answer is to cut off the 240v/12v transformer and hard-wire the screen to your boats 12 v supply (or through a dropper if you are on 24v) Before doing this, I decided to ask a few skippers, who I know had fitted them how they powered them, and that's where the fun started. One commercial skipper I had known had blown up two TFT screens by using the method described above and others had not experienced a problem . . .Strange! Another showed me his nice 17" TV/DVD screen where all the peoples faces were green! Alarm bells rang and I decided to do some digging on the Internet
I cam across a company called Amperor who told me this . . . . ..
TFT (Thin Film Transistors) are very susceptible to higher voltages than 12 volts and voltages of 13.8 volts and above cause damage to the thousand of TFT's that make up the picture on LCD TV's. The problem manifests itself in the loss of picture quality due to the loss of pixels on the screen that over a period becomes very noticeable. The voltage within the vehicles can vary between 10 and 15 volts depending upon the electrical loading of the 12 volt circuits and whether the batteries are being charged or not at the time. Amperors ADP-90DC-12 voltage stabilisers are designed to stabilise the 12 volt mark and will not let the voltage rise to anything near the point that cause damage to the TFT's
So if you find yourself wanting to power a domestic TV/Monitor, please do a little research first . . . . It could save you a lot of dosh"
