PCB Mount Potential Voltage Transformers

FERRTX TV3XXX Series｜PCB Mount Voltage Transformer for Precision Signal Isolation

*2500VAC Isolation & IEC 60044-2 Compliance in Harsh Environments*

Microprocessor-Grade Voltage Transformation

The FERRTX TV3XXX PCB Mount Potential Voltage Transformer redefines accuracy for industrial control systems. Engineered to transform primary AC voltages (50-400Hz) into isolated secondary signals (0.10V-7.07V), it achieves <0.1° phase shift – outperforming standard AC Voltage Transducers in PLC/DCS interfaces. With epoxy-encapsulated cores and asymmetrical PTH mounting, it withstands -40°C to +85°C extremes where conventional Isolated Voltage Transmitters fail.

Core Engineering Innovations

• Asymmetrical Footprint
  Enables 30% denser PCB layouts vs. symmetrical pcb mount power Transformers

• Dual-Core Material Technology
  Silicon steel (cost-optimized) or Nickel Alloy (±0.05% accuracy)

• Triple-Layer Insulation
  ABS/PBT housing + epoxy encapsulation + 1000MΩ dielectric resistance

• Transient Protection
  5000V surge withstand – 3× higher than basic DC Voltage Transducers
