Amp Pwm
Panasonic amp sa-xr70 fault code f70 pwm or pmw?
Had unit over 18months just had F70 (pwm or pmw) said to turn unit off Etc, Manual says go to dealer.
I was switching the unit from DVD mode (BiAmp) to CD mode (not BiAmp) using the 6.1decoding option when the fault code flashed up. The unit is back on and appears OK... its playing music.
Q1. What does the fault code actually mean?
Q2. Could it be some kind of power surge when switching from BiAmp to 6.1 decoding???
pwm or pmw dont know! F70 a 1.25a fuse has pos blown inside pls check inside to see if that is your problem. ... hope that helps

Charge Controllers in You Magnetic Power Generating System
You’ve constructed your magnetic power generator to save big bucks from your electrical utility bill. Now you want to put your system together, sort of like a cash register. Your very fist component you need to acquire is a charge controller. Without this component your system is dead and so are your potential savings. Here I will give you the ins and outs for what you need to know about charge controllers so you can save big on your utility bill while you are generating electricity at home. Most batteries will need fourteen to sixteen volts for optimal charging and the controller does this for you automatically.
Charge Controllers Protect Your Batteries
The charge controller regulates the flow of current coming from your magnetic power generator. You are making tons of energy from your magnetic generator and now you need a way to usefully control it. If you are sending too much voltage to your battery bank you can fry your batteries and permanently damage them, ouch!   Batteries are expensive so you want to protect them as much as possible. The charge controller works in the same manner as a voltage regulator in your car. Â
Types of Charge Controllers
Charge controllers come in all types of sizes, voltages, features, shapes, and price ranges. They range from small 2 amp shunt models all the way up to 80 amp MPPT controllers. The size you need will depend on the design load of your system. In other words, you need to know how much power you plan on using. There are three types of controllers: simple one or two stage control, PWM, and MPPT. The simple controllers are extremely reliable and disconnect the voltage when it reaches a certain level, but you don’t really see them around much anymore. The PWM controllers are what is readily available at the low to medium price range, and is the industry default controller now. The MPPT controllers are the best and most expensive available, and I want to expand on them more here.
MPPT is the King of Charge Controllers
MPPT, or maximum power point tracking, are the very best charge controllers you can buy. They are the most efficient controllers and can provide the most energy to the batteries. What they do simply is take the higher voltages coming in from your magnetic power generator and step it down to the correct voltage needed for your battery bank. It does this automatically regardless how much the incoming voltage varies. The MPPT looks at the voltage needed to charge the batteries, the amount of voltage coming in from the generator, and then converts this into the maximum amps to the battery. It does this very efficiently and safely and is the best choice for your zero point energy magnetic generator.
The correct charge controller is vital for generating electricity at home to achieve maximum energy savings. For smaller systems the static PWM controllers work just fine, but if you plan on generating large amounts of electricity to get the most savings then you will need an MPPT type controller. To learn more on how you can construct your own magnetic power generator, and become your own power company by generating electricity at home, check out this link: http://generating-electricity-at-home.canemanim.comÂ
