It is designed using very rugged LDMOS transistors. So, its efficiency is very high. It consists of 4 units VA2K model 2KW amplifier. It has reflection, current, unbalance and temperature protections. Output power can be set to lower powers. It has a room temperature and humidity sensor inside, so it automatically runs airconditioner according to transmitter room air condition. It keeps event logs. It has a remote control via ethernet or GPRS modem. N+1 redundancy system is ready to use.
