This Acti 9 iTR 25VA Safety transformer allows to obtain a very low voltage 12VAC or 24VAC from a network 230VAC. The transformer is safe, primary and secondary circuits are perfectly insulated by each other. The power supply is 25VA. The operating frequency is 50Hz or 60Hz. The primary voltage is 230VAC +/-10%. The secondary voltage output is from 12VAC to 24VAC. It is resistant to short-circuit currents thanks to the built-in-device. For 12VAC rated secondary voltage the Off load voltage is 14VAC. For 24VAC rated secondary voltage the Off load voltage is 28VAC. It is a Class II device with terminal shield (optional). The safety transformer should be mounted in vertical position only. The width in 9mm pitches is 10. The weight is 1309g. The degree of protection under IEC 60529 standard is IP20 with terminal shield. The dimensions are (W) 90mm x (H) 89mm x (D) 60mm. The width in modules of 18mm is 5. The operating temperature is -20°C to + 55°C. The storage temperature is -25°C to + 80°C. This product complies with IEC/EN 61558-2-6 standard.
