Accessories, Not Supplies
This category covers hardware that pairs with a power supply system rather than power supplies themselves — switch and multiplexer modules, remote sense accessories, power sensor modules, GPIB/interface adapters, and connector or cable kits. None of these generate power on their own; they support or extend a supply that's sourced elsewhere. If you need the supply itself, see our DC Power Supplies or AC Power Supplies categories.
Switch and Multiplexer Modules
Modules like the 34931T route a power supply's output to different test points or devices under test under programmatic control, letting an automated test system share one supply across multiple test positions instead of dedicating a supply to each. These typically install into a compatible switch mainframe or data acquisition chassis rather than working standalone.
Remote Sense Accessories
Remote sensing lets a power supply measure voltage directly at the load rather than at its own output terminals, compensating for voltage drop across long or high-current cable runs so the load actually receives the programmed voltage. This requires a separate pair of sense leads in addition to the main output leads, which is why remote-sense accessory kits are a distinct product from ordinary power cables.
Power Sensors and Interface Adapters
Power sensor modules measure a supply's actual output for verification or monitoring, while GPIB and interface adapters handle remote control and data logging connectivity for older supplies that predate more modern interface standards.
Brand and System Compatibility
Switch modules and sense accessories are frequently designed for a specific manufacturer's mainframe or supply family and won't necessarily work with a different brand's system. Check the listing for which supply or mainframe family an accessory is built for before ordering.
Frequently Asked Questions
What is a "power supply accessory," as opposed to a power supply itself? +
This category covers hardware that pairs with a power supply system rather than supplies themselves — switch and multiplexer modules that route power supply output to different test points, remote sense accessories that correct for voltage drop in long cables, power sensor modules that measure a supply's output, GPIB/interface adapters, and connector or cable kits. None of these generate power on their own; they support or extend a supply that's sourced elsewhere.
What does a switch/multiplexer module like the 34931T do? +
It routes a power supply's output to different test points or devices under test under programmatic control, letting an automated test system share one supply across multiple test positions instead of needing a dedicated supply per position. These typically install into a compatible switch mainframe or data acquisition chassis rather than working standalone.
What is remote sensing on a power supply, and why does it need special cabling? +
Remote sense accessories let a power supply measure voltage directly at the load rather than at its own output terminals, compensating for voltage drop across long or high-current cable runs so the load actually receives the programmed voltage. This requires a separate pair of sense leads in addition to the main output leads, which is why remote-sense accessory kits are a distinct product from ordinary power cables.
Are these accessories brand-specific to the power supply they pair with? +
Often yes — switch modules and sense accessories are frequently designed for a specific manufacturer's mainframe or supply family and won't necessarily work with a different brand's system. Check the listing for which supply or mainframe family an accessory is designed for before ordering.
