DCR600-20 DC Output Module
The DCR600-20 is a unique approach to generating programmable DC voltages to test
DC powered equipment using a Pacic Power Source AMX Series AC Power Source.
The DCR600-20 connects between the AC Power Source outputs terminals and the
UUT and recties the programmed AC output voltage into a stable DC voltage.
Pacic Power’s AMX and ASX-Series high performance Linear AC Power Sources oer
low output voltage noise and distortion, ease of installation, and high AC waveform
delity that is used to produce the required DC output voltage.
DC Test Capability From an AC Power Source
Leverage your existing investment in your AC Power Source by using it not only
for AC product development and test but for DC power products as well. The
same programmable features and function available on the AC Power Source
can be applied to an AC derived DC output. DC voltage is twice that of the AC
Line to Neutral voltage so scaling from AC to DC is easy.
Simple Connection, Quiet Operation
The DCR unit is placed between the AC Power Source output and the DC load
under test. For best results, a three phase AC Power Source is recommended. No
other equipment is needed to provide DC power. A set of banana jacks is provided on the DCR unit to connect a DMM which can be used to monitor the DC
output voltage. No DC bias supply is needed to operate the DCR unit and only
convection cooling is needed to cool the unit so no fan noise is present.
DC Test Sequence Programming
By programming the required AC voltage output sequence on the AC Power
Source, sophisticated test sequences can easily be applied to a DC unit under
test.
The Leader in AC Power Technology now oers DC
An early pioneer in the development solid-state power conversion equipment,
Pacic Power Source continues to develop, manufacture, and market both linear
and high-performance PWM AC Power Sources. Pacic’s reputation as a market and
technology leader is best demonstrated by its continuing investments in both research and development and world-wide customer support. With corporate owned
oces in the United States, Germany, the United Kingdom, and China, local personalized support is always available.
