SL Series power supplies have extensive diagnostic functions, including: phase loss, excessive thermal conditions, over voltage trip (programmable), over current trip (programmable), cleared fuse, and excessive program line voltage. When in standby or diagnostic fault, the AC mains are mechanically disconnected via an embedded AC contactor, providing confidence that the unit is only processing power when desired.
For maximum flexibility, all SL Series power supplies can be scaled in a master-slave configuration for higher voltage or current output. Using the plug and play Universal Interface Device (+UID47), units are tied together in via their 37-pin I/O, allowing an increase in system current when configured in parallel or increase in system voltage when configured in series—up to the power supply's output isolation rating.
All SL Series power supplies come standard with a National Instruments LabVIEW™ and LabWindows™/CVI drivers. In addition, an IVI driver is included supporting Visual C++, Visual C#, Visual Basic .NET, MATLAB, Measure Foundry, PAWS, Visual Basic 6.0, and Agilent VEE Pro. A Standard Commands for Programmable Instrumentation (SCPI) command set is also supported, allowing programming using raw ASCII commands. Finally, Magna-Power's RIS Panel software is provided allowing for a virtual control panel controlling the power supply via any of the available communication interfaces.
There are hundreds of possible configurations for the SL Series product. Using the following ordering guide and models chart to define the best model for your application. Need more power? Visit our XR Series product line.
