TR 28 SINGLE-PHASE TRANSFORMERS

TR 28 1.1. Safety or isolating single-phase transformers. IP20 protection index (finger safe). For mounting on DIN/EN rail up to 320 VA. Fast and easy connection due to the high capacity clamp type terminal blocks.

TR 28 2.2.-5.2. Control and safety or isolating single-phase transformers. They can supply high instantaneous power necessary for the correct operation of contactors and other switch and control gear. IP20 protection index (finger safe). For mounting on DIN/EN rail up to 320 VA. Great flexibility due to the several primary rated voltages with regulation taps ±15V (TR28 5.2) and the serial-parallel secondary connection.Fast and easy connection due to the high capacity clamp type terminal blocks.
