Chapter 1 General Information

Description

W a r n i n g

Outputs can be floated to maximum of ±240 Vdc provided that the metal shorting bars

without insulation are either replaced with insulated conductors or they are removed

from the terminals so there is no operator access to the output conductors without

insulation. All field wiring insulation must be adequate for the voltage present.

The power supply is shipped with a detachable, 3-wire grounding type power cord. The ac line fuse is an extractor type on the rear panel. The power supply can be calibrated from the front panel directly or with a controller over the GPIB or RS-232 interface using calibration commands. Correction factors are stored in non-volatile memory and are used during output programming. Calibration from the front panel or a controller eliminate the need to remove the top cover or even the need to remove the power supply from your system cabinet. You can guard against unauthorized calibration by using the “Secured” calibration protection function.
