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.

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.

Current Transformers
-
The Institute of Electrical and Electronic Engineers defines a current transformer (IEEE Std C57.13) as “a transformer intended to reproduce in its secondary circuit, in a definite and known proportion, the current of its primary circuit with the phase relations substantially preserved”. Its primary winding is connected in series with the conductor carrying the current to be measured or to be controlled and its secondary winding is connected to the measuring, protection or control devices. Osborne designs and manufactures current transformers which are used for instrumentation applications, others which are used for power system synchronizing applications and others which are used in protection circuit application. They have been designed to meet specified current ratios, burden impedance and transformation errors.

High Impedance Transformers
-
Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.

Multi-Element Standards
-
These multi-element standards consist of multi-layer thin film coatings, one on top of the other, upto a maximum of 6 elemental coatings. It is generally recommended to have coating thicknesses < 20 µg/cm2, so as to cause negligible notable matrix effects, in particular absorption of X-rays emitted in lower deposits by those covering them.
