Introduction
All legal and safety information for the Keysight RP7900 series also applies to the
Keysight SD1000A unit.
The Keysight SD1000A Safety Disconnect System (SDS) is an automated switching interface between
the Keysight RP7900 series power supply and the unit under test (UUT). It is intended to ensure
operator safety when the RP7900 power supply is used in a production environment. The SDS
provides the interface between safety inputs such as an emergency stop switch or fixture cover switch
and UUT, so that the operator is never exposed to harmful voltages when operating the test system.
The SDS contains redundant series-connected relays (two power and two sense relays) which provide
an additional level of safety when disconnecting high voltage from the UUT. The SDS is connected to
the Keysight RP7900 series power supply with a dedicated interface cable. Operation of the SDS is
integrated into the Keysight RP7900 series to make it work as though the relays are internal to the
power supply.
