GE Dash3000 Dash4000 Dash5000 patient monitor power supply board 801394-001 419477-001

► Brief Introduction

The monitor is powered at all times when it is plugged into AC power.When the monitor is not plugged in to AC power, this key turns the monitor On and Off.

When AC power is present, this key toggles the operational mode of the monitor between normal operation and stand-by mode. In standby mode patient monitoring discontinues. Only the charging function continues and the charging status indicators operate as described below.

The subsystems within the monitor operate from a common 9 to 18 V power bus. Due to the wide variety of voltages required by the various subsystems, power is converted locally by each subsystem. This architecture results in an efficient and compact system by reducing the number of conversions required and optimizing the PHiliphhilipysical size of each converter for the specific application.

When operating on AC mains power, the power bus voltage is 18 V, generated by the offline switching power supply.

No AC mains power switch is provided.

The line voltage range switch must be set to select 115 V or 230 V (90 to 132 VAC or 190 to 264 VAC, respectively).

► AC Power Indicator

The indicator illuminates green when AC mains power is applied to the monitor (including when the monitor is in the standby mode). The indicator does not illuminate when the monitor is not powered by AC mains power.

► DC-DC converter main section

The main DC-DC converter consists of two independent synchronous rectifier buck regulators with one common controller.

The monitor uses a “point of use” power conversion architecture with +9-18 V being the main power distribution bus.

Four voltage outputs are developed on the processor/power management PCB:

• +3.3 V,
• +5 V,
• –12 V, and
• –12 V.

Each one of the four outputs are individually current limit protected against overload and short circuit.
