Everyone’s under pressure these days to get results. So, there’s nothing worse than getting your bench test all set up, throwing the switch, and watching some of the magic smoke escape because of some setup error. To prevent this from happening when you’re under pressure, you need the Sorensen XBT 32-3FTP True Triple Output Digital Benchtop Power Supply.

The Sorensen XBT32-3FTP (see right) is a 16-bit triple output supply. Channels 1 and 2 can be programmed 0-32V and 0-3A each. The third output is fully programmable 0-15V, 0-5A up to a maximum of 30W. Channels 1 and 2 can be configured for tracking, parallel or series operation to, in effect, provide the equivalent of 6 different power supplies. In isolated mode, each of the 3 outputs functions independently; in tracking mode, channels 1 and 2 provide the same, but isolated output; in parallel mode, there is one 0-32V/0-6A output and one 0-15V/0-5A/30W output; in series mode, there is one 0-64V/0-3A output and one 0-15V/0-5A/30W output.

The Sorensen XBT32-3FTP benchtop power supply provides superior device under test (DUT) protection. Each output is fully isolated, and users can preview the voltage and current settings before turning on the outputs. This allows users to double check the settings before applying power to a valuable prototype.

The built-in output switches, in addition to enabling the preview mode, allow users to configure the outputs for parallel or series connection. When a user configures the supply’s output for parallel or serial connection, graphics on the front panel show the user how to make connections. This helps eliminate mistakes that could inadvertently destroy a DUT.

Other features that promote DUT safety include:

  • Configuration memory. The XBT can store up to 100 different configurations. Storing configurations in memory can help prevent set up mistakes which could damage a DUT.
  • Output timer. The built-in output timer can be set from one second to 100 hours. When the timer times out, the XBT turns off its outputs.
  • Power-on state and synchronous or individual control of each channel output. This is important when voltages supplied to a DUT must be applied in a particular sequence.
  • Over-voltage protection (OVP) and over-current protection (OCP). Users can program the OVP and OVC values separately for programmed for each output. OVC and OVP prevents a faulty DUT from drawing too much current that could cause subsequent damage to the device.

In addition to these safety features, the XBT offers all of the other features that you’d expect from a professional benchtop power supply, including excellent line and load regulation and remote operation via Ethernet, USB, GPIB, and RS-232 interfaces.
