TECHNICAL NOTES
ISOLATION VOLTAGE
‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test
voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Murata Power Solutions NMS series of dc/dc converters are all 100% production tested at their stated isolation voltage. This is 6kVDC for 1 second.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
The NMS series has been recognized by Underwiters Laboratory to a working voltage of 300Vrms for Supplementary Insulation system and 150Vrms for Reinforced
Insulation systems.
REPEATED HIGH-VOLTAGE ISOLATION TESTING
It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on
materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be
reduced by 20% from specified test voltage.
SAFETY APPROVAL
The NMS series has been recognised
by Underwriters Laboratory (UL) to UL 60950
for supplementary insulation up to 300Vrms
and reinforced insulation up to 150Vrms
working voltage.
File number E151252 applies.
