Mains power enters the system through the AC Inlet module (A), which includes a line
filter and the system circuit breaker. Mains power is routed through the Inrush (B)
board to the isolation transformer (C).
The Inrush board protects against voltage spikes and conditions the AC mains.
The isolated secondary output of the transformer (approximately 180 VAC) is routed
through two, 5-amp fuses (D) to the universal power supply (E). The DC output of the
power supply feeds into the Power Controller board (F). The transformer also supplies
isolated power to the electrical outlets through individual circuit breakers.
The Power Controller board interfaces with the system through:
• the Anesthesia Control board connector (G),
• the Display Connector board connector (H),
• the battery connector (I) and fan connectors (J),
• the Auxiliary Connector board connector (K).
