Power Distribution Units
Overview
The RMX-10050/10051 are a series of Power Distribution Units (PDUs) installed in integrated test
equipment platforms. Each PDU receives mains power through an inlet, and distributes that power to
various outlets. Some models may include an output sequencing feature, additional DC power
outputs, or a remote EPO feature. All models are constructed of a steel chassis and designed for fixed
mounting within an EIA-310 compliant rack enclosure.
There are two single-phase and two three-phase PDUs. The following tables provide
environmental ratings and feature information.

The AC output voltages provided by each PDU are based on the mains voltage and the specific
configuration. AC output ratings are also affected by the specific configuration.

When the DC output feature is included, it draws power from the AC mains, and affects the
available AC Output power. DC output ratings are shown in the following table.

Note All models, except the RMX-10050 (785342-01), include a DC output
feature. The total DC Output is always limited to 500 W. This is divided evenly as
125 W per each of the four output channels.
