The Atman BTR 400 VA 230/230V is a single-phase isolation transformer with open-frame construction (IP 00 — no enclosure). It provides galvanic isolation between the primary and secondary circuits at 230/230V, for service equipment, test benches, and industrial installations that require electrical separation between supply and load circuits.

Rated for continuous operation in air under normal ambient conditions, the unit measures 120×120×105 mm and is designed to be integrated directly into custom enclosures or equipment chassis.

Key Features

• Single-phase open-frame construction (IP 00)
• 230V primary / 230V secondary configuration
• Maximum primary voltage: 1000V AC
• Maximum secondary voltage: 500V AC
• Isolation voltage: 3750V AC (for 450V surge voltage)
• Dimensions: 120×120×105 mm
• Continuous-duty rated operation

Product Benefits

• Open-frame body integrates directly into OEM assemblies and custom enclosures without an additional outer shell
• 3750V AC isolation voltage delivers a robust safety barrier between primary and secondary sides
• Insulation classes B, F, and H accommodate different thermal load environments
• Class I construction allows earthing of the core and frame for an additional fault-protection layer
