Analog Power Supply
Type NPS-2412
-
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.

Injection Transformer
J2100A
-
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.

PeakTech Prüf- und Messtechnik GmbH
Due to the high safety requirements in service workshops, schools and industry, an isolating transformer is an absolute prerequisite for carrying out professional repair work. Galvanic isolation between primary and secondary voltage during measurements and repairs on open devices guarantees a high safety standard for the user. Of course, galvanic isolation from the mains voltage also offers other advantages in electronics development, audio technology and many other areas.

Auto Transformers
-
Osborne often recommends Auto Transformers in situations where reducing physical size of the transformer is advantageous. Auto transformers offer size advantages when compared to equivalent isolation transformers. Auto transformers provide lower levels of regulation than the equivalent isolation transformer. Osborne helps our clients accommodate for the loss of regulation while achieving the physical size (and cost) advantages of auto transformers.
