    Signal generator amplifier using only positive pole output, underperforming

    I have a 100W 50 ohms signal generator amplifier with a 35 meters coil wire (1.5 mm) as a load, BNC connectors. The requirement is that only the BNC POSITIVE pole is connected to the wire and used as antenna. The amplifier require a minimum of 4 ohms load. This is not a closed circuit antenna...

    How accurate are solar panel output readings?

    Hello Is it possible for solar panel monitoring to over state the actual power generated by the system? My friend’s 6.4kW system has generated 1280 kWh in the 82 days since its commissioning on 1/12/2022. Extrapolation of this output predicts an annual production of around 5,700 kWh which...

    Using solar panel DC output to feed immersion heater?

    Just an idle thought - has anyone any experience of using the DC output of solar panels to directly feed an immersion heater, to avoid the expense and losses associated with an inverter? Evidently, a changeover relay would be required to utilise the usual 240V AC supply at times of low or zero...

    Soldering 3.5 mm TRS cable to amplifier with +, - and OUT as output

    Hi! I want to solder a TRS cable to a circuit amplifyer. The amplifyer has +, - and OUT as outputs. I have heard that it should be possible to use a 3.5 mm TRS cable but I'm wondering to what output I should solder the wires from the TRS cable. Someone told me that I should use either TIP or...

    32A single phase output from 3 x 16A three phase supply. Is there a way?

    I have a workshop in a remote location which I rent out. The incoming supply is 3 x 16A three phase on 180m of 16mm SWA. An upcoming customer has a machine which needs a 32A single phase supply. (Actual load about 25A.) The energy is there, but it's split across the three phases. Is there some...
