ELECTRICALLY ISOLATED MODULE |
摘要 |
An electronic control module provides dual insulation layers between an internal line voltage and a separate tool housing that serves as a heat sink , thereby allowing versatility in mounting the electronic control module withi n the tool housing interior, and thereby also eliminating the risk of electrical shock to a user making contact with an exterior tool housing surface. The control modul e includes a power device, connected to a line voltage,arid a thermal pad. The power device provides a first layer of electrical insulation between the lin e voltage and an external tab of the power device while the thermal pad provid es a second layer of electrical insulation. The combined first and second layers provide a minimum amount of electrical insulation between the line voltage a nd the tool housing thereby preventing electrical shock. Alternatively, the thermal pad is provided between the control module and the tool housing.
