The RM's electrical circuitry consists of resistive element immersed in liquid and controlled by a FET switch, in turn controlled by a PIC micro controller. The firmware provides safety check and emergency shutdown if any parameters exceed specified limits or electrical connections become loose. In case of emergency the heater is able to discharge vehicle controller input capacitors. Open collector output allows to monitor status of the heater. All inputs/outputs are galvanically isolated from the high voltage (traction battery) circuit.
This Sierra model is very well suited for those niche applications where smaller capacities are required and higher voltages are available. Typically this compressor finds its home in air conditioning applications where 115 volts AC is being rectified to provide the DC signal
This Sierra model is ideally suited for applications where high voltage DC is available and small, precise capacities are required. It is also very well suited for applications where 230 volts AC is being rectified to DC
