Safety considerations
The QHS35-033 complies with IEC/EN/CSA 60950 safety requirements, providing basic insulation, input to output.
c-UL-us (US & Canada) recognized. An external input fuse, rated at 5A to 20/30A, fast-blow type, must be used to meet
the above requirements. The fuse will isolate the failed converter from the input source and protect the distribution
wiring from overheating. The output of the converter is considered to remain within SELV limits when the input to the
converter meets SELV requirements
The converters are designed to meet UL 94V-0 flammability ratings.
