SAFETY
Constructed in accordance with IEC 60950-1,
EN 60950-1, and UL 60950-1, supplementary
insulation, 250Vrms maximum working voltage,
flammability class V-0.
There are no special installation requirements
(beyond attending to usual PCB track separations)
since the integral cover provides supplementary
insulation from its external faces to internal core
and windings.
Additionally, Profec Technologies certifies all
transformers as providing voltage isolation of
2.12kVrms, 3kV DC minimum. All shipments are
supported by a certificate of conformity to current
applicable safety standards.
