The Atman CTR M/S 1250 VA 230/230V is a single-phase isolation transformer of the closed (enclosed) type. It delivers galvanic isolation between primary and secondary circuits in a 230/230V configuration, suitable where electrical separation is required for safety or suppression of conducted interference.

Designed for continuous operation in air under normal ambient conditions, the unit carries an IP 20 degree of protection, shielding internal windings from solid objects larger than 12 mm.

Key Features

• Single-phase closed-type construction
• 230V primary / 230V secondary configuration
• Maximum primary voltage: 1000V AC
• Maximum secondary voltage: 500V AC
• Isolation voltage: 3750V AC (at primary voltage 450V)
• Degree of protection: IP 20
• Continuous-duty rated operation

Product Benefits

• Galvanic isolation at 1250 VA handles heavier loads than lower-rated CTR M/S models
• Insulation classes B, F, and H offer thermal flexibility for varied installation environments
• Closed construction prevents contact with live windings and limits dust ingress above 12 mm
• Class I earthed enclosure adds a fault-protection layer for personnel safety
