It is very widely used in the RV industry. This is a Parallax Series 7100, Model 7155, 55-amp RV Power Converter. Well I thought I had this fixed after replacing the caps, but in real time use, it is still not working correctly, so I'm back for help. ) brand of capacitors.Įvery morning is the dawn of a new error. lies one HELL (x100) of a ferrite based inductor !Īlso, as you have already found, its dang nigh impossible to find that S.H.I. Located betwixt the cooling fan and the central MAIN power transformer. If so, that might be your units REALproblem. that it has a domed cap pooching upwards at its triangular imbedded stress striations. do look back at the fans direction, and don't you see an intermediate size E-cap that. Now, relevant to your passing judgement, do you visually see any physical fault or electrolytic leakage being associated with those two big boys ? That with gradual time, just heat up and eventually dehydrate those caps electrolyte. So, typically, they are QUITE trouble free, as being compared to the other caps that handle the decades or hundreds of kilohertz of switching cycles of HARD pulses / square waves operating frequencies. They DO operate at a VERY non taxing S.L.O.W up and down sinusoidal 50/60 cycles. Its rectified DC comes back to those two black capacitors for filtering. In " reading " the board, I am seeing AC power coming in the right bottom corner and then getting an X capacitor, then a contrawound line inductor pair and yet another X cap and a line fuse and then over to the right to a heat sink mounted FULL WAVE RECTIFIER block. ![]() PLUS I would be changing the pair simultaneously. Then DO ALSO NOTE +- 20% so, you are just fine, just be sure of the +105 degree temp range due to its potential rough temperature environs that it may be subjected to. Note that the circuit board does list the cap values under the removed caps. Thanks in advance for what I'm sure will be another interesting education. If it matters, the mains are on the right side of that board and the DC output on the left (white and blue wires). Pics of the board and the cap are attached. So my question is, would I be able to get away with a 1000uF (or other suggested option) cap in place of this, or does that alter the eventual DC output voltage of the unit? There are two of them on the board and the application is for an RV power supply from 110vac to 12vdc, so it both powers the 12 volt electronics in the RV and acts as a house battery charger when plugged into AC. There are tons of 1000uF's with the correct dimensions, and those would be very close, considering there is often a 10-20% tolerance with these things. I've tried the common online supply stores (Digikey, Mouser, Arrow) and ebay and amazon. I realize substituting capacitors with higher voltage and temperature ratings is acceptable, if you cannot find the exact spec replacements, but I am trying to replace a cap that I cannot find the same uF rating for. This was my last, but obviously, most trusted attempt. ![]() I have tried to find a definitive answer to my question on my own, however, I am not confident in what I have found. 7100 Series models also are FCC Class B certified, attesting that they minimize signal interference with televisions, radios, and emergency channels.Hi all. The full output rating is available for battery charging. The filtered power is free from spikes and surges, helping to maintain smooth operation of appliances, lighting and amenities. Other features include a steel chassis, ventilated steel door, fuse clips which withstand jarring and road vibration, and the industry's most trusted lower converter section with filtered DC power. ![]() The 7100's distribution panel meets the requirements as a CTL Class I listed enclosed panel board, an important safety benefit. Parallax Power Supply 55Amp Replacement Converterħ100 models feature solid construction and quality components which stand up to the rigors or Rving?mile after miles, year after year, in all types of climates.
