General

AITR series isolation transformer is specially used in medical IT system, and the core superposition adopts the silicon steel sheet imported from Japan, which has very small losses. The windings are treated with double insulation and have electrostatic shielding layer, which reduces electromagnetic interference between windings. The PT100 temperature sensor is installed in the wire bag to monitor the temperature of transformer. The whole body is treated with vacuum invasion paint, which increases mechanical strength and corrosion resistance. The product has good temperature rise performance and very low noise.

Installation & Wiring

Note:

1) The S terminal wiring can select 2×4mm² yellow-green wire. The wiring of two ST terminals can select 2×1.5mm² shielded twisted pairs, and the wiring should not be too long.

2) The connection line diameter of the input and output of the isolation transformer should match the rated current of the isolation transformer, or it can be selected according to the following table:
