  • Thermoelectric self-powered hydronic heating demonstration
    An inverter changes power to 115 volt 60 Hz for the delay timer and the gas ignition and control. The control operates at 24 volts 60 Hz on the other side of a transformer .
  • Automatic collector of samples for determining isotope washout curves in muscle tissues
    This will start the supply of power from the mains ( 115 V AC) to the transformer T1. The secondary coil of the transformer is so connected that 24 Volts D C are obtained at the outlet of the rectifying circuit.
