Description
The Atman CTR M/S 400VA is a single-phase closed-type isolation transformer designed for service workshops, laboratories, and industrial test benches that need galvanic separation between the mains and a powered device. With a 230V primary feeding a 230V secondary, it provides a one-to-one isolated supply for safer fault diagnosis and operator protection.
Construction is closed type with IP20 protection, class B/F/H insulation, and a continuous-duty rating, allowing operation in normal cold ambient air. The series limits are documented below for reference.
Key Features
- Single-phase isolation between mains and load for safer servicing
- Closed-type enclosure protects windings and terminals from accidental contact
- Class B/F/H insulation system supports a wide operating temperature window
- IP20 protection rating against finger contact with live parts
- Continuous-duty rated for permanent installation in test or workshop benches
Product Benefits
- Galvanic isolation reduces shock risk when probing live circuits during repair
- Closed-type design simplifies fixed installation in cabinets and panels
- Continuous operation suits long bench sessions without forced cool-down periods
- Class I preparation aligns the unit with standard protective earthing practice
- Series withstand voltage of 3750V AC (referenced to a primary of 450V) supports demanding service scenarios
