DESCRIPTION

This is a three-phase transformer which, depending on the model (TRI-122 or TRI-123), has a transformation ratio of either 220V to 22/38V or 380V to 22V-38V, with an apparent power of 300 VA.

The output voltage is 22V between phases (12.7V neutral phase) and 4 Amperes or 38V between phases (22V neutral phase) and 3.75 Amperes which can be selected by means of a commutator on the front template.

The output is by both 4mm and 2mm bushes and they are protected against overcurrent and shortcircuit with a light indicator per phase. They are thermally insulated with resetting being produced automatically after the protective elements have been cold for a period of time.
