" POWER SAVER HQ for AMIGA!" FULL BLACK :-)
PROFESSIONAL POWER SAVER PROTECTION FOR:
WORLWIDE EXPERIENCE: To date a couple of people have contacted me thanking me after their crazy Meanwell PSU failed the voltage went up :-O ... but with the OVP the AMIGA was saved ... the only thing burned were the two fuses of protection! OH YEAH! ;-))
This "Power Saver HQ" is different from ordinary protectors: it is professional . And it was created to protect all the Commodore AMIGA power supplies according to the list. The protection is complete for: +5 VDC
It is completely made of semiconductors with very fast intervention times 20us (microseconds!), no relay on board that would require long intervention times 200ms (milliseconds!).
What does it means this time value? It means 10.000 time fasters then relay-based protections . This is the only way we can safely safeguard our Commodore vintage computer
This electronic circuit allows to keep under control the voltages supplied by the AMIGA power supply by detecting anomalies on the correct value.
The most critical power supplies of the Amiga are the + 5Vdc and the + 12V which are used for all the ICs present on the motherboard. Instead the -12VDC power supply is used only to power the IC LF347 which manages the audio part and is the least critical. In the case of voltage values out of range the POWER SAVER HQ intervenes promptly with times equal to 20 / 40uS thanks to the use of semiconductors instead of relays
POWER SAVER HQ is equipped with four LEDs in order to control its functionality:
1) ON: your AMIGA is working and it has +5VDC under safety threshold 2) OFF: there's a problem!
ACTION TO TAKE
2a) Protection has occurred ... and your Commodore AMIGA is SAFE!Open the Power saver and change the fuse (T2.5A). Before turn it on check /repair your power supply.
2b) There isn't +5VDC output from the "Power saver HQ " . Check the presence of 5VDC at the input of "Power saver" and/or check if your original power supply is connected and if it works
1) ON: your AMIGA is working and it has +12VDC under safety threshold 2) OFF: there's a problem!
ACTION TO TAKE
2a) Protection has occurred ... and your Commodore AMIGA is SAFE!Open the Power saver and change the fuse (T630mA / 800mA). Before turn it on check /repair your power supply.
2b) There isn't +12VDC output from the "Power saver HQ " .Check the presence of +12VDC at the input of "Power saver" and/or check if your original power supply is connected and if it works
1) OFF : All ok. Your Commodore AMIGA is working properly. It means that all voltages are under the safety threshold according to power supply specification. 2) ON: There's a problem! It means that at least one of the three voltages is beyond the threshold and the power supply must be checked.
1) ON: All ok. It means that +12VDC and -12VDC from is coming out from your AMIGA power supply 2) OFF: There's a problem!It means that one or both are missing (+12VDC & -12VDC) from your AMIGA power supply
