Philips Respironics V200 Esprit Power Supply Replacement

Introdução

This guide is for the Philips Respironics V200 / Espirit Ventilator, Part Number 580-1000-02. The power supply converts AC voltage to DC voltage to be used by the system electronics. The switching power supply can accept voltage from 100 to 240 V AC (50/60 Hz), and converts it to +5 V, + 12 V, and +29 V DC voltages. In the absence of AC voltage, the power supply converts the +24V DC input voltage from an external DC power source (Backup Battery or External Battery). The power supply also includes power fail logic and charging circuitry for the backup battery.The power supply is cooled by a 24 VDC fan housed in a shroud covering the power supply PCB.

Information about removing and installing the power supply can be found in the Service Manual in Chapter 10.10.1-2 on pages 10.22-24. In order to remove the power supply, you must also remove and reinstall the power supply shroud and MMI PCB. Information on these topics can be found in Chapter 10.8 on page 10-21 and Chapter 10.12 on page 10-26 in the Service Manual).
