National RF’s Type NPS-2412
Thumbnail Picture - Click to Enlarge
National RF's Type NPS-2412 analog power supply was designed to
be used in communication equipment where radiated switching inverter noise from
conventional “switching type” supplies is not acceptable. The power supply
consists of a standard rectified transformer output driving a pair of voltage
regulators and filtering networks. The 2412 offers an adjustable voltage output
between 2 and 24 volts as well as a fixed voltage output of 12 volts. A maximum
of 20 Watts of DC power can be supplied from the unit. As the voltage regulators
dissipate power in the regulation process, the power to the load is derated
accordingly, dependent on the set voltage to the load. The adjustable regulator
is a standard LM-317T integrated circuit device. The fixed regulator is a
standard LM 7812 device. Upon customer request, the LM 7812 device may be
changed to any voltage rating within the the LM-78xx series of regulators.
Contact National RF for this modification if desired.
