Page 7: Using The Instrument
Fuses 6. Using the instrument The LNF-PBA uses a transformer, rectifiers and regulators to convert mains AC to ±12V DC needed for LNF’s HEMT power supplies. There are 8 identical output connectors on the front panel providing the ±12V to the HEMT power supplies. All 8 outputs are connected in parallel and are not isolated from each other. -
Page 8: Maintenance And Service
There are no serviceable parts in the instrument. If the ventilation holes are clogged with dust, disconnect the instrument from the mains supply and use a dry cloth to gently clear the ventilation holes. Low Noise Factory • www.lownoisefactory.com • info@lownoisefactory.com... -
