Atman BTR 300 VA Open-Frame Isolation Transformer – 230/230 V, 3750 V AC & Class I

The Atman BTR 300 VA 230/230V is a single-phase isolation transformer with no enclosure (IP 00 — open construction). It delivers galvanic isolation between the primary and secondary circuits in a 230/230V configuration, for service equipment, test benches, and industrial installations where circuit separation is essential.

The unit is rated for continuous operation in air under normal ambient conditions. Its compact dimensions of 120×120×95 mm make it easy to integrate 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)
