A programmable power source delivers you remote capability to control the output voltage and current. As there are many programmable varieties and supply models in the market, you should consider a few before getting a programmable power supply concerning your needs.
Number of Outlets
This depends on how many applications you’re planning to run. Generally, speaking, it’s good to have a programmable power source with multiple outlets, so you don’t waste time connecting each load individually. However, make sure the outputs are isolated. Isolated outlets can be operated in parallel or separately, giving you more flexibility and control during simulations.
Safety Components
Most programmable units come with safety components that continuously monitor the output voltage and current, constantly comparing them with the set reference value. In case there’s an overload of energy, your load source is automatically shut off.
Cooling System
Cooling technology is also involved in keeping a programmable power source safe. Overheating of a system negatively affects the components, costing you hefty sums in maintenance. Getting a unit with a powerful built-in cooling system such as conduction or convection cooling is a good idea.
Output Enable/Disable
This is an optional feature, but it’s recommended for most users. It allows you to switch the output on or off without completely shutting down the load. It’s great for testing equipment efficiently.
Constant Current Versus Constant Voltage Application
As standard power supplies already provide constant voltage, most people prefer using programmable sources for applications that require a constant current. A constant current source is ideal for high precision electrolysis, thermal testing, and generating electromagnetic fields. You may go for a constant voltage if your application is focused on automotive part testing or capacitor forming. For more information, please visit Amp-Line Corp.
