  • Page 15: Load Considerations

    Note that the output will become unstable if the following types of loads are connected. Loads with peak current or pulse-shaped current The PWX750ML only indicates mean values. Even when the indicated value is less than or equal to the set constant current, the peak values may exceed the set constant current. If this happens, the PWX750ML is instantaneously put into constant-current mode, and the output voltage drops.

  • Page 16: Specifications

    Connecting a load with accumulated energy, such as a battery, to the PWX750ML may cause current to flow from the load to the internal circuit of the PWX750ML. This current may dam- age the PWX750ML or reduce the life of the load.
