FAQ
Q: What is a trigger transformer used for?
A: A trigger transformer generates high-voltage pulses to reliably trigger SCRs, TRIACs, xenon flash tubes, and gas discharge tubes (GDTs) in ignition and control circuits.
Q: What is the difference between a trigger transformer and a standard transformer?
A: A standard transformer is designed for continuous power transfer, while a trigger transformer is designed for switching applications. It delivers short-duration, high-energy pulses with a fast rise time for reliable triggering.
Q: Can the turns ratio be customized?
A: Yes. SHINHOM offers custom turns ratios, inductance values, and other specifications to meet the requirements of specialized trigger circuits.
Q: Are the TCB Series trigger transformers RoHS compliant?
A: Yes. All TCB Series Trigger Transformers are manufactured using RoHS-compliant materials and meet current environmental regulations.
