Optocoupler Tutorial and Optocoupler Application

Optocoupler Applications. Optocouplers and opto-isolators can be used on their own, or to switch a range of other larger electronic devices such as transistors and triacs providing the required electrical isolation between a lower voltage control signal, for example one from an Arduino or micro-controller, and a much higher voltage or mains current output signal.

What Is The Basic Insulation Level (BIL) | EEP

The minimum level is known as the Basic Insulation Level (BIL) ... it is necessary to define surge voltage in terms of its peak value and return to lower values in terms of time or duration. Although the peak voltage may be considerably higher than normal voltage, the stress in the insulation may exist for only a very short period of time. For purposes of design, the voltage surge is defined ...

Use creepage in a sentence | creepage definition

At the worst environment with no coating this goes up to 3.2mm creepage. Airgap clearance is a fair bit smaller at this voltage, from 0.2mm to 0.8mm depending again on the environment. The clearances and creepages are defined in e.g. EN 60950 and EN 62368 standards. Connectors usually define a max working voltage, that's what you can safely use ...
