Description

The Agilent 6621A-6624A, and 6627A Multiple Output Linear Power Supplies feature a combination of programming capabilities and linear power supply performance that make systems applications. The five models in this family offer a total of up to 200 watts of output power, with voltages up to 50 volts and currents up to 10 amps. The output combinations that correspond to each model are shown in Table 1-1. Each isolated output can supply power in two ranges as shown in Figure 1-1. This flexibility allows you to use the same output to power loads with different voltage and current requirements. No separate command is required to program ranges; the power supply automatically selects one of the operating ranges based on the last parameter (voltage or current) that is set. Additionally, each output contains an active downprogrammer, which means that voltage downprogramming can be accomplished as quickly as upprogramming, even without a load.

The output voltage and current for any output can be monitored with the front panel display. Output specific error messages are also displayed. Front panel annunciators show the operating status of the instrument. The front panel keypad lets you set and readback the voltage limit, current limit, and overvoltage trip level of any output. With the keypad, you can also enable or disable outputs, mask and delay bits in the fault register, enable overcurrent protection, reset overvoltage and overcurrent protection, and return to local operating mode.

Your multiple output power supply can be both a listener and a talker on the GP-IB. (GP-IB is Agilent Technologies’s implementation of IEEE-488). The built-in interface is tailored to the supply, resulting in simpler programming. Voltage and current settings can be sent directly to the specified dual range output in volts and amps.

Service can be requested from your power supply for up to ten reasons. The supply responds to a serial poll by identifying the output on which the fault occurred. Self-contained measurement and readback capability eliminate the need for externally scanning the outputs using a separate DVM. Upon command the supply will measure its output voltage or current and return the value on the GP-IB. The following functions are implemented via the GP-IB:

Voltage and current programming.

Voltage and current measurement and readback.

Present and accumulated status readback.

Programmable service request mask.

Programmable overvoltage and overcurrent protection.

Storage and recall of programmed voltage and current values for all outputs.

Queries of programmed functions or settings.

Output enable or disable.

Programming syntax error detection.
