The Atman CTR M/S 500 VA is a single-phase isolation transformer in a closed enclosure, rated for continuous operation. It features a 230V primary and 230V secondary winding with a 3750V AC isolation voltage, suited to applications demanding galvanic separation between supply and load at a 500 VA power level.

The unit carries Class I protection, insulation classes B, F, and H, and an IP20 degree of protection. It is designed to operate in air under normal ambient conditions.

Key Features

• Rated apparent power: 500 VA
• Primary voltage: 230V AC / Secondary voltage: 230V AC
• Isolation voltage: 3750V AC (tested at primary voltage of 450V)
• Closed-type enclosure with IP20 protection

Product Benefits

• 500 VA capacity accommodates heavier loads such as larger instrumentation racks, medical devices, or industrial control panels
• 3750V AC isolation voltage offers a substantial safety barrier between supply and downstream circuits
• Galvanic isolation suppresses common-mode noise that affects measurement and control equipment
• Continuous operation rating supports around-the-clock industrial or laboratory use
• IP20 closed enclosure prevents direct contact with live windings in panel installations
