This Product Selection Guide contains information to help select products in the Power Entry Modules (PEM) category on DigiKey.com
Power entry connectors include inlets, outlets, and modules designed to handle power. Some are designed to filter out unwanted frequency (EMI, RFI) from a circuit. These are often thought of as “heavy duty” power connectors as some can handle extremely high amperage or voltage. Connector styles include various IEC and NEMA along with some specialized for different countries. Some feature a circuit breaker and/or switch and different ingress protection (IP) levels.
SelectionCharacteristics
Connector Style: An indication of the type of connection being use. Typically meets a standard.
Connector Type: Indicates the style/format of the connectors used to connect this product.
Current Rating - Appliance Inlet: Typically this represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components. For the input of the device.
Voltage Rating - Appliance Inlet: Typically this represents the maximum voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components. For the input of the device.
Number of Positions: The total number of electrical conductors the device has.
Filter Type: Indicates if the items has a filter and the type of application the device is designed for.
Current Rating - Filter: Typically this represents the maximum current to which the filter of a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Switch Features: Indicates if it has a switch and type if so.
Current Rating - Circuit Breaker: Typically this represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Accomodates a Fuse: Indicates whether or not a part includes accommodations for a fuse.
Mounting Type: Indicates how the device is attached.
Termination: Selection of termination style used to connect the device to a system, such as crimp, solder, or wire leads.
Features: These are different capabilities or properties of the device such as board lock, cover, or shielded.
Fuse Holder, Drawer: Indicates number of fuse-protected lines in the module and whether a fuse drawer is included or sold separately.
Panel Cutout Dimensions: Refers to the measurements or dimensions of the opening or cutout in the panel.
Panel Thickness: The thickness or range of thicknesses the device would need to be able to mount properly in a panel hole.
Material Flammability Rating: Ensures compliance with the relevant UL Flammability Rating.
UL94 Small Scale Flammability - Relative Comparison
