Low DC Inlet Power Supply
B.3.1
22 Vdc to 67 Vdc ONLY, Terminal Power Strip, SWC
The Low DC power supply replaces the Universal power supply with a three-position, screw-type terminal
block, including Surge Withstand Capability (SWC). With DC ONLY inlet voltages from 22 Vdc to 67 Vdc,
this feature is intended for use in installations where it is necessary or desirable to have the instrument power
hard-wired.
WARNING:
Do not apply AC voltages to the inlet terminals.
