FRENIC Solar Pump

  • Optimal Operationg Point Calculation Function At every Start the inverter determines the optimal operating point depending on current conditions. MPPT Function
  • During Operation is searches the working point that provides maximum power. The conditions (Mainly temperature and irradiance) will change during operation
  • Start Criteria by PV Panel Voltage and Time Stop Criteria Selectable by Frequency or Power
  • At every Start / Stop the inverter determines the optimal operating point depending on current conditions
  • Detection of Sudden Changes of Conditions (Especially irradiance) Detects a sudden changes in the operating conditions and changes the working point accordingly.
  • Dry Pump Detection Function Detects that the water is not reaching the pump Water tank maximum Level Detection If the Tank level reaches the maximum level the pump will stop Two Sets of PID gains The PID Controller has to respond rapidly or slowly depending on the operating conditions changes.
  • Low Power Function It indicates that the output power is low.For example due to dust on the solar PV Panels. IEC Approval For rated output efficiency measurement (IEC61683) and climate test (IEC60068) as per standard.

MD2 Series

  • The MD2 series 2-phase stepper motor drivers allow extremely precise motor control with low mechanical noise and low vibration operation.
  • The isolated photocoupler input design minimizes influence from electrical noise.
  • Low vibration operation is possible with the microstepping drive function (MD2U-MD20).
  • Unipolar constant current drive method
  • STOP current setting provides holding torque (brake function)
  • Low vibration operation with micro stepping drive (MD2U-MD20
