    _______________________________________________________________________________ Section 4 - Circuitry Description Overview The Aquamantys Pump Generator is comprised of the following components: • Power supply unit with mains transformer, power supply PCB (Supply_TL1) with rectifiers, filter capacitors and an inrush current limitation circuit. • RF generator PCB (RFGEN_TL1). This PCB comprises the entire internal voltage processing circuit, the RF generator, the motor controller for the peristaltic pump, 2 microcontrollers for sequence control and monitoring the entire process.

  • Page 21: Description Of Unit Components

    _______________________________________________________________________________ Description of unit components Primary power supply Mains voltage reaches the power supply PCB via a line filter socket and an illuminated power switch. The mains transformer connects to this PCB. The mains voltage reaches the mains transformer’s split primary winding via an inrush current limitation circuit and a voltage selector (115 V/230 V).
  • Page 22 _______________________________________________________________________________ The power supply PCB (Supply_TL1) and the mains transformer comprise the power supply unit, which is mounted on an aluminum plate. This power supply unit is fastened in the housing with 4 screws. The mains voltage reaches the Supply_TL1 circuit input (mains socket, J1) via the line filter socket and the power switch.
