• Manufacturer Part Number: ds2d01r
• Description: Delphi Ds2d00r Series Dc/dc Power Modules 5, 12, 24, 48vin, 2~3w Dip
• Manufacturer: Delta Electronics, Inc.

Design & Feature Considerations
Maximum Capacitive Load
The DS2D00R series has limitation of maximum
connected capacitance at the output. The power
module may be operated in current limiting mode
during start-up, affecting the ramp-up and the startup
time. The maximum allowed capacitive load is listed in
table on page 2.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as
practicable across the load will give the best ripple and
noise performance.
To reduce output ripple, it is recommended to use
1.5uF capacitors at the output.

Overcurrent Protection
To provide protection in a fault (output overload) condition,
the unit is equipped with internal current limiting circuitry
and can endure current limiting for an unlimited duration.
At the point of current-limit inception, the unit shifts from
voltage control to current control. The unit operates
normally once the output current is brought back into its
specified range.
Soldering and Cleaning Considerations
Post solder cleaning is usually the final board assembly
process before the board or system undergoes electrical
testing. Inadequate cleaning and/or drying may lower the
reliability of a power module and severely affect the
finished circuit board assembly test. Adequate cleaning
and/or drying is especially important for un-encapsulated
and/or open frame type power modules. For assistance
on appropriate soldering and cleaning procedures,
please contact Delta’s technical support team.
Notes:
1. These power converters require a minimum output load
2. These DC/DC converters should be externally fused at
to maintain specified regulation (please see page 6 for
the suggested minimum load). Operation under no-load
conditions will not damage these modules; however,
they may not meet all specifications listed above.
