40-66V DC\/2900W PROGRAMMABLE MAINS POWER SUPPLY WITH OPTIONAL LCD DISPLAY AND RS232 REMOTE CONTROL<\/strong><\/p>\n

\"\"<\/p>\n

DESCRIPTION:<\/strong><\/p>\n

Perfect for TV and FM pallets, can support more than 2000W of RF power.<\/p>\n

This slide-in 2900W max mains power supply is extremely compact and fits 2H rack easily. It is available with voltages of 48V, 60V and 66V. If you need another voltage please contact us. PSU features a built-in fan. A number of protections are built-in. Each mains power supply comes with plug-in connector board. It also simplifies installation and you can install and swap mains power supplies easily without any soldering. Units are enclosed in metal case, tested and guaranteed to be working worldwide (100V-300V\/45-65Hz). Please note output power is derated at 110V so use 220-240V for maximum power output.<\/p>\n

Perfect for new 60V 1800W LDMOS fets PA: MRFX1K80H<\/strong><\/p>\n

NOTE:<\/strong> Each mains power supply comes with plug-in connector board for mains and DC output. This makes it possible to swap mains power supply easily without any soldering (slide-in design).<\/em><\/p>\n

\"\"LCD control module for 1800W\/2900W mains power supply:
\nThis LCD control module plugs into the mains power supply and talks to it via CAN bus. It makes it possible to:
\n\u2013 Change and save voltage (you can disconnect the module after saving voltage, if you wish)
\n\u2013 View output voltage and current
\n\u2013 View mains power supply temperature
\n\u2013 Monitor mains voltage at the input
\n\u2013 Turn a fan on and off as desired depending on mains power supply temperature
\n\u2013 Same size as our other LCD modules with 3 keys
\n\u2013 RS232 remote control is possible via terminal, see manual for commands. Our IO board is required.
\nFor more info look under Additional info tab above as there is a manual explaining wiring and functions.
\nImportant: LCD control module requires DC power supply, about 9V to 15V @ about 400mA of current.<\/p>\n

20-80V to 15V DCDC converter<\/strong>
\nEasy way to get 12-15V from your main 65V supply for new LDMOS. This tiny DCDC converter board will reduce your 48V-80V power supply voltage down to 15V. This can serve to power the LCD control unit or other electronics. Simply connect 20-80V DC input and you will have output voltage 15V.<\/p>\n
