Max 150 W(Input 10W). Max 300 W(Input 10W) Max 250W (Input 5W). Compact high power all mode amplifier with automatic TX/Rx switch and On/Off switch. Dear customer, if you want to reach the PE MAX output, please check that the input should exactly 10W or 5W, the DC Power should actually be over 14V and 18A and also other conditions should be perfect.However, we do not suggest to work the PE Max for a long time, it will decrease the amp' life time and also if the antenna can not endure the output watt, which will damage the amp, thank you very much!
