Product Information
8650B Series, RF Loads are compact high-power 50-ohm terminations efficiently dissipate up to 50 kW of RF over a wide frequency range up to 900 MHz.
- Interlock control circuit provides fail-safe protection of the transmitter and load resistor in the event of an ac power failure to the blower or coolant pump.
- Compact, low-profile design saves space in crowded transmitter sites.
- Available Voltage Options (add suffix to model number)
- 115V @ 60 Hz (-115)
- 230V @ 50 Hz (-230)
- 230V @ 60 Hz (-230-6)
