Catalog Data Sheet

M Series

The M series power entry modules offer the most choices of power entry components and filtering options to fit a specific need. The fully configured M series expands the options of a manufacturer whose products are marketed worldwide. One component, fully assembled and tested, provides the capability of interfacing a multi-voltage power supply to any common voltage or fusing scheme in the world, without modification.

The IEC connector provides an internationally accepted power entry termination, which can be used with a variety of line cords.
The selectable fuseholder allows use of single or dual European fuses, or a single North American fuse.
The optional DPST on/off switch breaks both sides of the line and is labeled with the international I/O markings.
The optional voltage selector provides a convenient means to change transformer primary connection, and it is available in both 2-voltage and 4-voltage configurations.
The series is available with four filter circuits to meet a variety of applications, and convenient connections are provided on unfiltered models to allow wiring of a separate RFI filter.

The M series is a family of components offering greater flexibility and cost-effectiveness in the selection of primary power components. Wiring to the modules is accomplished via .110” terminals for labor savings and convenience. Four filter circuits provide a choice of attenuation tailored to specific categories of susceptibility and emissions needs.

HM Models – This medical filter provides susceptibility protection without the leakage current associated with line-to-ground capacitors. Designed to allow equipment to meet UL544 for patient care and non-patient care equipment, the HM filter has a maximum leakage current of 2 μA at 120 VAC 60 Hz.

FM Models – General purpose RFI filter designed for susceptibility applications, effectively providing RFI control of line-to-ground noise. The design is compact and meets the very low leakage current requirements of VDE portable equipment as well as (120 Volt) UL544 non-patient medical equipment.

XM Models – High performance RFI filter designed to bring most digital equipment (including switching power supplies) into compliance with FCC Part 15J, Class B conducted emissions limits.

ZM Models – Premium RFI filter designed to bring most digital equipment (including switching power supplies) into compliance with EN55022, Level B (as well as FCC Part 15J, Class B) conducted emissions limits.

See Appendix C for more information on UL544 or UL2601 health care applications.

Note: When using the models with an IEC connector, remember that the leakage current of the companion line cord, GA400, is more significant than that of the filter - which may disqualify this line cord from use in patient care applications.

Voltage Selection

To change selected voltage: open cover, using small blade screwdriver or similar tool; set aside cover/fuse block assembly; pull voltage selector card straight out of housing, using indicator pin; orient selector card so that desired voltage is readable at the bottom; orient indicator pin to point up when desired voltage is readable at bottom (note that when indicator pin is fixed, successive voltages are selected by rotating the card 90° clockwise); insert voltage selector card into housing, printed side of card facing forward toward IEC connector and edge containing the desired voltage first; replace cover, and verify that indicator pin shows the desired voltage.
