Transfer Relay Assembly (A13)
A high-voltage relay mounted in the rear case that routes current from the A15 Energy Storage Capacitor, by means of the A22
Biphasic Module, through the W11 Therapy Connector Cable to the patient. Activation of the A13 Transfer Relay is governed by the
A04 Therapy PCB Transfer Relay Control block.
Inductive Resistor (A14)
A resistor that conditions the energy storage capacitor output for the wave generator/regulator circuit on the A22 Biphasic Module.
Energy Storage Capacitor (A15)
A metallized film capacitor used for energy storage. The capacitance of the A15 Energy Storage Capacitor is calculated when you
perform the TCP – Defibrillator Energy Calibration procedure. The nominal value is 195 μF.
SpO2/SpCO/SpMet Module (A16)
An OEM oximetry module supplied by Masimo. The module performs all functions related to oxygen, carboxyhemoglobin and
methemoglobin saturation, including sensor drive. Measurement results pass serially by means of the A06 OEM PCB to the A01
System PCB ASIC for display.
Interconnect Bracket (A17)
A terminal assembly used to interconnect the A13 Transfer Relay Assembly, A22 Biphasic Module, and A15 Energy Storage
Capacitor. The bracket itself is strapped to the A15 Energy Storage Capacitor with a large cable tie.
