features intelligent power control function: 1. The output power base on the principle of Channel 1 + Channel 2 = 400Watt. 2. If only one channel is used, the output power come from channel 1 can approach to MAX. 400 watt, channel 2 can approach to MAX. 200 watt. 3. If both channels are used, the output power of channel 1 equals 400 watt minus output power of channel 2. 4. Start channel 2 while channel 1 is using fully 400 watt,the output power of channel 1 will be reduced accordingly. Features: Intelligent power control. Optimized operating software.
