Standards

IEC/EN 61558-1 Transformers, general specifications
IEC/EN 61558-2-2 Control transformers
IEC/EN 61558-2-4 Isolating transformers
IEC/EN 61558-2-6 Safety transformers
RoHS Compliant

Constructive characteristics

Two identical secondary winding intended for serial or parallel connection (jumpers supplied with the transformer)
Windings in F(155°C) or H(180°C) thermal class
Flexible insulation Class B(130°C)
Impregnation Class B(130ºC)
Great capacity clamp type terminal blocks:

up to 320VA > 10mm2 (max. torque 2Nm)
up to 1000VA > 25mm2 (max. torque 2,5Nm)

Screw earth connection (standard IEC/EN61558 prescribes in the clause 24 that it should not be possible to loosen the protection wire without the aid of a tool)
TIG welded magnetic core prevent vibration and allows small air gap to reduce the magnetization current
Fixing on symmetric rail in rated power up to 320VA
