Industrial TR20VA020 Transformer

The RIB TR20VA020 MobiltEx transformer is a 20 VA Class 2 power transformer with a 12 VAC secondary and a dual 120/240 VAC primary, designed to deliver a steady low‑voltage supply from standard mains. With a 12 V output capable of about 1.7 A, it is suited to powering relays, sensors, instrumentation, or other small loads inside control panels or equipment enclosures where Class 2 safety limits apply. The unit carries CL2 insulation rating and uses RMU3 mounting, making it appropriate for indoor installations that require safe, code‑compliant wiring and a compact form factor. The part designation T01A42TR201 identifies this specific MobiltEx variant, allowing precise ordering and replacement in systems that specify the TR20VA020 model. This transformer’s 120/240 VAC input makes it usable in a wide range of power environments, while its fixed 12 VAC output provides a predictable supply for low‑voltage circuits. The 20 VA rating sets the maximum available power, guiding designers to size loads and protective devices accordingly.
