You can see examples of power amplifiers that we made on YOUTUBE. You will need a case and power supply only! You can turn the power amplifier. The water will not flow.

The power supply may be for example: FlatPack2 HE. 100W input power with ATT.

Running the second level at a copper radiator temperature is more than 50 degrees Celsius. Stop transmission for copper radiator temperature is more than 80 degrees Celsius. Voltage 13.8V 1.5A.
LCD - out power and VSWR. LED indication of protection operation by SWR, current and maximum output power. Installed on the cable output SO-239 TRX cable SO-239. Power amplifier protection device: Protection from exceeding the output power of 1200 watts. Protection against exceeding the maximum drain current of the LDMOS transistor.

Protection against overheating - two thresholds of operation: when the copper radiator is heated more than + 50 - the accelerated mode of the fan operation is activated to increase the heat removal. When the copper radiator is heated above + 80 ° C, the protection system trips, breaking the PTT circuit.

Protection against exceeding the SWR more than 2.0: 1. The activation of the SWR protection is independent of the output power level Protection against false / spontaneous band switching in LPF. The activated protection channel is indicated by a lit LED on the front panel of the power amplifier.

To reset the error, it is necessary to switch off and on again the power supply of 48-53.7 V. Size 240 mm x 260 mm x 140(h) mm. BOX for this power amplifier. The item "LDMOS HF amplifier 1200W output BLF188XR 1.8-54 MHz water coolling" is in sale since Thursday, October 18, 2018.
