due to advances in technology, specifications subject to change without notice.
NOTES
1) Efficiency (%) measured at maximum load.
2) These converters require a minimum load to maintain specified regulation.
3) All dc/dc converters should be externally fused at the input side for protection,
consult factory for more information.
4) Other input and output voltages may be available, please consult factory for
more information.
5) Specifications subject to change without notice.
6) Operation under no-load conditions will NOT damage these converters however
they may not meet all listed specifications under such conditions.
7) Transient recovery time is measured to within 1% error band for a step change
in output load of 75% to 100%.

Units are encapsulated in a low thermal resistance molding compound that has excellent resistance/electrical characteristics
over a wide temperature range or in high humidity environments. The encapsulant and unit case are both rated to UL 94V-0
flammability specifications. Leads are tin plated for improved solderability.
