Electrical energy consumption limiter device for peripheral, has dissipative resistor and thermosensitive unit with positive temperature coefficient that are cabled in series, where unit presents low ohmic value when mains voltage is low

摘要

The device has an assembly of a dissipative resistor (3) and a thermosensitive unit (4) with positive temperature coefficient that are cabled in series. The assembly is connected in parallel on a controlled peripheral (2). The thermosensitive unit presents a sensitivity threshold to the current traversing it and a low ohmic value when mains voltage is low.
