    Safety

    Safety within the undergraduate power laboratory is paramount and the EPLTS range incorporates many essential safety features.

    • All power and measurement connections made via fully shrouded safety 4mm sockets
    • Complete galvanicĀ isolation for all user control interfaces
    • Controllers are separately powered from the power stage
    • Separate controller power enables operation from near zero voltages up to the power stage's maximum power ratings
    • The ULK-LOD1 has an interlock to protect against operation without fan cooling
    • Software fault detection power stage shutdown
    • Fuse Protection of power signals
    • Earthed Case

    Flexibility

    Each test set is easily reconfigurable, allowing them to be used in experiments ranging from single diode rectification to switching of multi-phase inverters.

    The EPLTS also supports custom programming. Standard library support structures are available to aid software development and postgraduate research work.

    Controller upgrades are available that include the latest Texas Instruments Microcontrollers.
