EXB30 Series
Single output
Total Power: 16-30W
Input Voltage: 36-75VDC
# of Outputs: Single
The EXB30 is a new high efficiency open frame isolated 30 Watt
Special Features
High efficiency topology, converter series in an industry standard footprint. The first five
92% typical at 5 V
models in the series feature a 2:1 input voltage range of 36 Vdc
Industry standard footprint
Wide operating temperature,
to 75 Vdc and are available in output voltages of 12 V, 5 V, 3.3 V,
-40 C to +85 C
2.5 V and 2 V. Each model is trimmable from 80% to 110% except
(natural convection)
80% to 110% output trim
the 12 V output which has a wider trim range of 60% to 110%.
No minimum load
Overvoltage and The sub 5 V models have an output current rating of 8 A. Typical
overtemperature protection
efficiencies for the models are 92% for the 5 V, 90% for the 3.3 V

and 12V, 87% for the 2.5 V and 86% for the 2 V version. The EXB30
Available RoHS compliant
series offers remote ON/OFF and remote sense compensation to
2 year warranty
correct for voltage drops at the load. Overcurrent, overvoltage
and overtemperature protection features are included as
standard. With full international safety approval including
EN60950 and cUL1950, the EXB30 reduces compliance costs and
time to market.process
