The DMPS-10 AC Power Supply provides all dc operating voltages and current required by up to
four fully-populated RDC-01 or RDC-02 chassis. The rack mounted power supply plugs directly
into a standard 110 Vac primary power source outlet. This power supply can also be set for use
with 240 Vac. The power supply comes equipped with one nine-conductor power cord and an AC
line cord. The DMPS-10 will power one PS assembly and can house up to three additional
DMPS-10 EXP expansion power modules to supply power for four PS chassis assemblies.
