Agilent 6675A Power Supply Product Review

Agilent 6675A Power Supply Product Review

Well known throughout the industry, the Agilent 6675A lives up to its billing as a quality, technician friendly power supply. It’s the top line model of the 6670A series power supplies on offer from the popular test equipment maker Agilent, making it an excellent resource to any testing laboratory. It offers superb reliability and low noise outputs in an affordable package.

1777833-40

It’s durability is renowned in the field, and high customer satisfaction ratings are keeping the demand strong for both used and refurbished models. This 2000 watt DC power workhorse is very efficient and offers a much lower operating noise than other similar units in its class. The advanced fan speed control make the Agilent 6675A perfectly suited for use on the bench. The result is very subtle ripple and acoustic noise is being emitted, making for highly accurate voltage and currency measurements.

 

Durable and Easy to Program

Easy programming of DC output and the multi protection features is possible by using the GPIB, and can be quickly accomplished from accessing via the front panel or by use of SCPI standard commands. When combined with the serial link, the user is able to connect up to 16 power supplies all through one GPIB address. The analog signals will allow the user to easily control the output current and voltage. This can be especially useful by displaying instant reactions to process changes in many types of high noise settings. Additionally, even more simplification of testing system integration is possible by the use of VXI Plug and Play drivers. The many optional accessories that are available separately include:

 

  • ●    4-pin Digital Plug
  • ●    7-pin Analog Plug
  • ●    Accessory Slide Kit
  • ●    Serial Link Cable

Characteristics of the Series

The Agilent 6675A has an excellent reputation and is loaded with technician friendly features which include a very fast Command Processing Time. After receiving the digital data, the time needed for output voltage to start to change is only 20 ms for the power supplies that are connected with the GPIB directly. Also, up to one half of the rated voltage can be dropped in each load lead. Other characteristics of note include:

 

  • ●    dc Floating voltage: (Its possible to float the Output terminals up to ±240 Volts dc from chassis ground)
  • ●    Modulation: (Analog programming of output voltage and current)
  • ●    GPIB Interface Capabilities: PP0, DC1, DT1, E1, SH1, AH1, T6,L4, SR1, RL1, and C0. (IEEE)
  • ●    Input Power: 3,800 VA, 2,600 W at full load; 170 W at zero load
  • ●    Input Impedance: 60 k Ohm or higher
  • ●    Input Signal: 0 to –4 V for voltage, 0 to 7 V for current
  • ●    Output Common-Mode Noise Current: (to signal ground binding post) – 500 µA rms, 4 mA peak-to-peak
