Magnetic Amplifier (Positive & Negative Feedback)Product Categories: Control Lab, Control Lab, Electronics, Engineering Equipment Product Page: https://www.labappara.com/product/magnetic-amplifier-positive-negative-feedback/
Product DescriptionMagnetic Amplifier Trainer Positive & NegativeAmplification is the control of a larger output quantity by the variation of a smaller input quantity. Such amplification can be performed by a magnetic device called Magnetic Amplifier or Magamp. This set up is designed to study the basic characteristics of such amplifier with +Ve & “Ve feedback. The set up consists magnetic amplifier, AC and DC power supply, two meters for load and control currents and a fixed value RL. The set up to study the characteristics of magnetic amplifier, has two identical gate windings wound upon split deltamax cores, which are joined together to form a common central limb. The DC control winding is wound upon this central limb with the amplifier feedback winding in / out mode. A control bias battery in form or regulated DC 0-3 volt supply with a DC m Ameter to read IC, and current limit resistance is provided to study control winding may be changed with polarity selector. Afixed value (50 ohm) RL with stepped down fixed AC supply, with a dc ammeter to read load current IL, is provided with gate winding To study input-output characteristic of a magnetic amplifier
