IHB60S Series Approved to
UL/CUL 1950, EN60950
The IHB60S series standard half brick modules are designed for today’s
demanding industrial applications. Available in two wide range inputs,
these isolated converters offer many features in the standard models.
With a complement of safety agency approvals and low noise operations,
the converters respond extremely fast to change in load conditions.
Inherent in the design are very well-controlled output voltage and no
need for minimum loading.
