  • Buck Transformers and Boost Transformers
    Buck transformers and boost transformers are used in series with line or power supply voltages to buck (reduce) or boost (increase) voltages. They are typically versatile and can be used to correct for voltage line drops, or to adapt to international voltage variations. While buck transformers
  • Control Transformers
    Industrial control transformers are designed to supply the required power (voltage and current) needed to operate industrial control units such as relays, solenoids, PLCs, and other control components. Control transformers (also known as machine tool transformers) provide isolation to control
  • Donut Transformers
    Donut transformers, also called toroidal transformers, have no internal primary winding as such. The primary is the conductor in which the current is to be monitored, and is not an integral part of the transformer. The primary conductor is simply placed through the window of the current transformer
  • Wideband Transformers
    Wideband transformers couple signals magnetically from input to output terminals with optimum transmission fidelity over broad frequency ranges. Major objectives in their use are: 1. Impedance matching for maximum power transfer. 2. Coupling between unbalanced and balanced circuits. 3. DC isolation
  • Bar Transformers
    Bar transformers (bar current transformers) are toroidal transformers with a bus bar permanently inserted through the window of the toroid. The bus bar serves as the primary conductor. Bar transformers are inserted directly into the circuit which they will be used to monitor. It is a common error
  • Ferroresonant Transformers
    Ferroesonant transformers are special transformers that accept variable input voltage and puts out regulated AC voltage. Ferroresonant transformers are used independently to prevent fluctuations or may be built into more functional devices such as uninterruptible power supplies. Limitations
  • Current Transformers
    Current transformers (CT's) provide a simple, inexpensive and yet accurate means of sensing current flow in power conductors. They are available in 3 basic configurations: Split Core CT's are available for measuring currents from 100 to 5000 amps, with windows in varying sizes from 1" by 2" to 13
  • Transformer Theory
    A transformer is an energy transfer device. It has an input side (primary) and an output side (secondary). Electrical energy applied to the primary is converted to a magnetic field which in turn, induces a current in the secondary which carries energy to the load connected to the secondary
