POWER SUPPLY PROTECTOR UNIT

This device disconnects the PA output transistors from power supply voltage in case of failure, for example when SWR in antenna exceeds the level set. This unit works paired with high SWR protection unit.

Three IRF5210 transistors are capable to switch the current up to 30 A. No relays are involved in protection circuit, so it is very fast and safe.

The +24V (for cooling fans) and +15V voltage regulators are added onboard.

Do not use microcontroller as a HI SWR protection device, it is too slow.
