摘要

The heating plate device has thin-walled, good heat conducting heating plate (1) arranged in a housing (4). The heating plate is heated at the bottom by positive temperature coefficient heating element. The plates are provided with a plane base. The device is connected to voltage by a power cable. The supply of energy takes place by a connection at the local supply voltage. An operating voltage is transferred to the heating plate by interconnection of a power supply unit in voltage less than the line voltage.
