    3.2. Power supply connection The input blocks of the Remote Heat Station should be bolted onto the output of an Induction Heating power supply. The RHS is rated for up to 40kW at up to 400kHz. Consult the manufacturer for use beyond those limits. 3.3.
  • Page 7 WARNING: Make sure that the circuit breaker is turned off before adjusting heat station components. Loading resonant capacitors onto the RHS capacitor bus. Figure 2: Changing the capacitors 4.2. Tuning. This section provides the procedures required for the final tuning of the heat station for a specific heating coil and load.
  • Page 8 3. It is necessary during tuning to measure the current in the RHS cable using the oscilloscope with a Rogowski coil. The cable current can not be above 300amps. 4. It is also useful to measure with an oscilloscope the voltage at the RHS capacitor rail. Using a differential voltage probe monitor the Voltage across the RHS capacitor rail and compare it to the unit display.
