FAQ
What power range do your low-frequency transformers cover?
From PCB pin types under 25VA, through 25–500VA and 500VA–2KVA, to large isolation and control transformers above 2KVA.
Which safety standards do they meet?
They can be designed to UL 5085, IEC/EN 61558, PSE, VDE and others, with certification support.
What information do you need for a quote?
Input voltage and frequency, output voltage and current (or VA), mounting, size limits, safety requirements and estimated quantity — a drawing helps.
