Determining property of unchanged load device

Abstract

Determination devices (1) determine properties of load devices (2) that may remain unchanged for said determining and that comprise first channels with first elements (20, 25). The determination devices comprise first switches (10) for providing first invitation signals to the first channels, detectors (15, 16) for detecting first response signals that result from the first invitation signals, and controllers (17) for deriving the properties of the load devices (2) from detections of the first response signals. The properties define first maximum values of first loads of the first channels, and the controllers (17) calculate first maximum duty cycles of first supply signals for supplying the first channels in view of the first maximum values of the first loads and power capacities of power supplies (3) that produce the first supply signals. The load devices (2) may further comprise second channels with second elements (21, 26), and the determination devices (1) may further comprise second switches (11).
