5.5 Warning
1. Check the power supply voltage is between 24V and 32V or not before electrify, better
to setup in 30V. Power of power supply shall bigger than 1400W.
2. Ensure the power supply polarity is right, port A1、A2 are anode, and port A3、A4 are
cathode.
3. Ensure the output line is connected and input power is not over load before connect
the RF input line.
4. Use the type N connector as output connector, for the high output power, suggest to
using the φ3 upwards RF cable to connect. At the same time, output matching deman
d all right, SWR more than 1.5 is better, but less than 3.0.
5. Product operating should be cooled by air flow, air flow more than 150cfm.
6. Product operating room temperature can’t above 50o ,also can’t below -20o。
