Description
The Agilent 6551A models are 500 Watt, single output, series pass regulated power supplies, with front panel and analog programming of output voltage and current. Up to five front panel settings can be stored in nonvolatile storage registers for later recall.
This reliable series of 500 W dc power supplies can be controlled
either from the front panel or via an analog programming voltage. When
used in a test system, the fast up and down programming helps
decrease test time. Quickly reacting protection features, including fast
crowbar, CV/CC mode crossover and over-voltage protection help protect
your valuable assemblies from damage. The linear topology produces
very low ripple and noise, which allows you to make extremely accurate
measurements of the devices which you are testing.
Lab bench use is enhanced by the fan speed control, which helps to
minimize the acoustic noise.
