Auxiliary Current Transformers
Osborne Auxiliary Current Transformers are often used to reduce system currents to lower values appropriate for instrumentation and/or protection circuits. The Aux CT’s are designed for specific current ratios and burden impedance with a known transformation error. Osborne’s units are built for high performance and longevity in the most demanding environments.

Control Transformers
Osborne’s Control Transformers are commonly used to step down primary circuit voltages to lower voltages to be used for control circuit applications. These units set the standard for premium, high performance, hand crafted control transformers. Your customers will appreciate your decision to work with the quality and reliability of Osborne Transformer’s control transformers.

DC Filter Inductors
Osborne DC filter inductors (aka filter chokes) are commonly used in AC to DC conversion circuits to present an inductive voltage drop to the AC component of rectified current. This inductive voltage drop acts as a filter. Osborne designs filter inductors to components to function effectively (without saturation) in the presence of the DC current. Osborne will work with you to mitigate the impact of ripple frequency in conversion circuits. Every Osborne DC filter choke is designed for high performance with special consideration given to your circuit´s power supply frequency and conversion configuration.

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.

Isolation Transformers
Osborne’s Isolation Transformers are used to step-up, step-down and isolate voltages in single phase circuits. Isolation may be used to provide output circuit immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the input system. The isolation can allow separate grounds on both the input and output sides of the transformer. Osborne also designs with a range of electrostatic shielding to provide several levels of noise immunity.
