Intrinsic Safety Systems
The HB04UC Series is a low-cost, high-isolation voltage, unregulated, single
and dual output DC/DC converter. The dielectric withstand characteristics of
each converter is tested in production to ensure barrier integrity.
The HB04UC Series uses advanced circuit design and packaging technology
to realize superior reliability and performance. A 100kHz driven push-pull
oscillator is used to ensure stable frequency and non-saturating operation
of the input stage. This means there are no high peak voltages or currents
like other design topologies, which can reduce unit reliability. Reduced parts
count adds to the reliability of the HB04UC Series.
The high effi ciency of the HB04UC Series means less internal power dis-
sipation. With less heat to dissipate, the HB04UC Series can operate over a
wider ambient temperature range with no degradation of reliable operation.
The HB04UC Series offers the user low cost without sacrifi cing reliability.
The use of surface mounted devices and manufacturing technologies make
it possible to offer premium performance at low cost.
