What We Build
Custom Solutions, Built Around You
We're more than a manufacturer — we're your engineering partner. Every project starts with a conversation, not an invoice. Backed by ISO 9001 certification, UL/CSA/ETL recognition, and 60+ years of magnetic design experience, we solve problems other manufacturers turn away. No job too big. No job too small.
Current transformers (CTs) for accurate metering, protection, and monitoring.
High-frequency designs for switch-mode supplies, EV charging, and industrial electronics.
Compact, low-loss transformers for switch-mode and high-frequency power conversion.
Galvanically isolated, electrostatically shielded designs for clean, safe power.
Power distribution unit transformers for data centers and critical power.
Fast-edge pulse transformers for signal coupling, gate drive, and timing.
Voltage conversion for machinery, imported equipment, and OEM gear.
Boost lower input voltages to the higher levels your equipment requires.
Three-phase transformers for industrial power, distribution, and high-load applications.
Low-noise, high-efficiency cores for audio, medical, and instrumentation.
Voltage (potential) transformers for safe, accurate high-voltage measurement.
Output, power, and choke transformers for guitar amps — stock or custom.
Catalog Parts AvailableSingle and three-phase distribution units up to 750 kVA.
Catalog Parts AvailablePad-mounted transformers for commercial and utility sites.
Capabilities — applied to any type above, never sold as a separate product
Dual-primary windings and multi-tap configs for 50 / 60 / 400 Hz equipment sold worldwide.
Compact, low-profile builds that drop into tight PCB layouts and sealed enclosures.
Multi-winding, high-voltage, oddly-shaped assemblies that other shops turn away.
Industries Served
From NASA payloads to guitar amplifiers, Pacific Transformer's custom magnetics power some of the most demanding applications in the world. Our engineering team has deep experience across industries where compliance, performance, and reliability aren't optional — they're required.
