Application-Specific FAQ
Q: Is this transformer suitable for 24/7 continuous duty?
A: Yes. The METH series is rated for continuous operation. Ensure adequate ventilation around the unit per EN61558-1 installation guidelines.
Q: Can I use this transformer to power a Siemens S7-1200 PLC system?
A: Yes — pair it with a 24VDC SITOP or equivalent regulated PSU on the secondary side. The isolation transformer provides upstream mains isolation and noise filtering.
Q: What is the difference between METH and METS series from JEIL TRANS?
A: METH designates the standard safety isolation transformer series. METS typically refers to toroidal variants. Contact us to confirm the correct series for your application.
Q: Does this unit comply with UL standards for North American markets?
A: This model is certified to EN/IEC 61558-1. For UL 5085 compliance (North America), please contact us — we can source UL-listed variants.
Q: Can you supply a test report or certificate of conformity?
A: Yes. CoC and test reports are available upon request for qualified buyers. Contact our team with your order reference.
