Palstar DL150HP Owner's manual

  • Hello! I have reviewed the technical manual for the PALSTAR DL150M and DL150HP Dummy Loads. This manual describes the specifications, operation, and features of these devices, including their 2500W power handling for 1 minute, 600W continuous duty, and their thermostatically controlled fan cooling system. I'm ready to answer any specific questions you might have about the described items.
  • What is the maximum power handling for 1 minute?
    What is the continuous duty power rating?
    What is the frequency range of the device?
    At what temperature do the cooling fans activate?
