Extremely high-performance extra-low voltage power supply, can also be used as a constant-current source and as a delta current generator. Can be deployed e.g. for generating a current which rises and falls linearly over time for experiments on the relationship between the induced voltage and the change in the magnetic field strength over time, or as a high current power supply like
521 55.
In addition to the functions of the high current power supply (see
521 55), the delta current power supply is equipped with a switchable delta current generator which generates a constant dI/dT, continuously adjustable in the range from 0.2 ... 2.2 A/s. The maximum current (up to 20 A) and the maximum voltage (up to 24 V) can be limited to protect connected apparatus, just as in power-supply mode.
