Mindray SV300/SV350 Ventilator EV20 DC-DC Power Supply PCBA Board (Brand-New Refurbished Version)

Compatible Models

Compatible with Mindray SV300 and SV350 EV20 ventilators; serves as the core DC power supply board for the entire unit.

Product Application

The core component for voltage conversion in the entire unit, converting the input voltage into multiple stable DC voltages to power all modules, including the main control board, inspiratory ratio valve, fan, and display; resolves issues such as the device failing to power on, a black screen, frequent reboots, fan failure, power supply fault alarms, and unstable ventilation parameters.

Product Features

Brand-new original manufacturer power supply board with new capacitors and power management chips, free from aging-related degradation; features built-in multiple safety protections against overvoltage, overcurrent, and short circuits;

Original manufacturer’s standard interface layout with plug pins that perfectly match the device; plug-and-play replacement without the need for rewiring or debugging;

Voltage output calibrated at the factory; all output voltages comply with the ventilator’s original manufacturer quality control standards, allowing the device to be put into clinical use immediately after replacement;

Brand-new-for-used-parts program: The faulty power supply board must be returned after repair, offering a more cost-effective solution.

Installation Precautions

Disconnect the ventilator from the AC power source before disassembly or installation. Allow sufficient time for residual capacitance to discharge to prevent static electricity from damaging circuit board components;

When connecting or disconnecting ribbon cables, gently press the latches; do not forcefully pull the cables or bend the circuit boards to avoid damaging the pins;

After installation, power on the device and thoroughly test the power-on sequence, fan, display, and all ventilation modes. Confirm there are no abnormalities before clinical use;

As these are precision medical circuit boards, they are not eligible for a 7-day no-reason return or exchange. Please confirm model compatibility with SV300/SV350 EV20 before placing an order.
