Internal Discharge Resistor Module
The Internal Discharge Resistor Module contains the internal discharge resistor, and a means for dissipating the heat generated by the internal
discharge.
AC/DC Charger Module
The AC/DC Power/Battery Charger provides a universal (IEC 320) connection to the AC mains or to a DC source, input line filtering and double-
pole fusing (for a mains input), AC-DC and DC-DC conversion and isolation barrier between the M
Series and power sources. This module also
provides the power necessary to run the M Series in any mode of operation, as well as providing additional charging current to the battery. When
the M Series is turned off but connected to an external AC or DC source, the charger module controls battery charging currents and voltages needed
to charge the M Series battery. These voltages and currents are controlled in response to the main CPU signals that manage the battery charging
process.
System Interconnect Module
The system interconnect PWBA receives signals from the Main System Board and in turn controls operation of the stripchart recorder and PCMCIA
functions.
XPACE_SEL: Hardware only signal from the front panel switch that is at '0'
during pace. Used as an additional safety interlock on the solid
state patient relay so that operation of the relay during pacing is
additionally disabled.
