The PTA ultra-isolation transformers series is designed for high-noise environments
where shielding is required to ensure good signal quality.
This series has two types:
• With 1 electrostatic shield (PTU1P) for minor perturbations between primary and
secondary
• With 3 electrostatic shields (PTU3P) for high perturbations at the start
