FIELD: engineering of testing equipment, possible use as imitators of non-linear stepped load of uninterruptible power supply devices.
SUBSTANCE: devices has rectifying bridge, diodes, capacitor batteries and loading resistors. Additionally included are contacts of launch key, limiting resistor and relay, having two groups of normally disengaged contacts, which, with appropriate circuit for connecting to each other, and also to loading capacitor and loading resistor form a loading contour, while device includes N loading contours ( N>=1), connected in parallel to each other to output of rectifying bridge.
EFFECT: possible stepped alteration of nonlinear load value and limiting value of launch current during increase of the former.
