  • Air-blocks for 25%, 40% and 50% openings are available. Airflow will be turbulent
  • The load board controls each of the six main board zones through front panel switches
  • Each zone dissipates a nominal 35W
  • The RTM has two switch controlled zones each of 10W
  • The total dissipation of the front board is limited by software to 225 Watts. Power is provided independently to each of six zones
  • Each zone can be set to a value between 0to 51.2 W in 100mW increments
  • The total power dissipation of the RTM can be set to up to 35W watts
  • Note: this power is taken from the front board
