Single-Phase Isolation Transformer for Medical and Control Equipment
Model FPIT · Single Phase · 120 V – 690 V secondary · Class F / Class H
Product Summary
The FPIT single-phase isolation transformer delivers reliable galvanic isolation between primary and secondary circuits for single-phase loads such as medical equipment, control equipment and sensitive electronic systems. A low-loss CRGO core and high-conductivity copper or aluminum windings support rated capacities from 1 kVA to 5,000 kVA, primary voltage up to 15 kV and secondary voltage from 120 V to 690 V. An optional electrostatic shield helps reduce common-mode noise reaching sensitive downstream devices.
Key Features
- Galvanic Isolation for Sensitive LoadsSeparates primary and secondary circuits to support medical, control and electronic equipment power systems.
- Optional Electrostatic ShieldA copper or aluminum shielding layer between windings reduces common-mode noise and electrical interference.
- Low-Loss CRGO CoreGrain-oriented electrical steel with optimized magnetic circuit design lowers no-load losses and audible noise.
- Class F / Class H InsulationHigh-performance epoxy resin, Nomex, polyester and high-temperature insulating paper, with 80 K or 115 K temperature rise options.
- Compact Enclosure OptionsAN or AF cooling with indoor or outdoor powder-coated steel enclosure rated IP00, IP21 or IP23.
- Market ComplianceBuilt to applicable IEC, IEEE, ANSI and UL requirements, with CE certification under EN IEC 61558-1, EN IEC 61000-6-1 and EN IEC 61000-6-3.

Models and Options
The FPIT range includes general-purpose, drive isolation, K-factor, single-phase and three-phase isolation transformers. Single-phase units are ordered by rated capacity, primary and secondary voltage, tap range, winding material, electrostatic shield requirement, cooling method and enclosure type, with impedance, connection and vector group set to the application.
Materials and Structure
The magnetic circuit uses high-quality grain-oriented electrical steel with an optimized core design. Copper or aluminum conductors are wound with a reinforced insulation system that may include epoxy resin, Nomex, polyester insulation and high-temperature insulating paper. Where electrical noise must be limited, a copper or aluminum electrostatic shield is placed between the primary and secondary windings. The heavy-duty powder-coated steel enclosure protects the unit in demanding environments.
Customization
Primary and secondary voltages, rated capacity, impedance, tap configuration, temperature rise, winding material, electrostatic shielding, cooling method and enclosure protection degree are configured per application. Production follows the applicable IEC, IEEE, ANSI and UL requirements for the destination market.
