  • Page 14 The output voltage (Vset) and output current (Iset) of the DC-DC converter can be changed according to the user’s needs. This provides flexibility for the PROTIUM-375 to be compatible with various DC motor’s voltage input range. To protect against current overdraw or to maintain the fuel cell’s output at its most optimum power level, Iset can also be configured to limit the maximum allowable current output.
  • Page 15 Iset can only be changed via the PC DAQ GUI app. Follow the instructions on Section 3 until step no.1 of section 3.2. After the welcome header appears in the message box of the GUI, use the keyboard function of the GUI and type the following command: ‘i’...

    5. Connect the power/signal receptacle (1) of the PROTIUM-375 to the power/signal header (11) of the electronic controller, using the power signal extension cable (26/27).
  • Page 21 Hydrogen gas flow rate of more than 5L/min. 4. PROTIUM-375 will do a series of gas purging and internal diagnostic checks. If everything is normal, the fuel cell will enter its “Running Phase” – indicated by the message in the GUI and a solid white LED.
  • Page 22 3.3 POWERING YOUR LOAD WITH PROTIUM-375 1. Turn ON your load and draw power as per normal. Caution: never draw power beyond 375W. If Iset is implemented, the fuel cell will not deliver more than the Iset current to the load. Excess power required by the load would then be supplied by the supercapacitors pack.
