Sunray SRF618B Fetal Monitor Power Fuse Board G2D9BEC 2A 250V Replacement Circuit Board

• Product Description

This is a specialized power fuse board designed specifically for the Sunray SRF618B fetal monitor. Identified by the PCB model number G2D9BEC and marked as "POWERLINK V22," this component serves as the primary power distribution and protection unit within the device. The board features two glass tube fuses rated at 2A/250V, which are critical for preventing electrical surges from damaging the main motherboard. It includes standard connectors (J1 and JP2) for easy integration with the monitor's internal wiring harness. This replacement part is essential for technicians repairing units that fail to power on or have blown fuses due to voltage instability. It ensures the safe and stable operation of your medical monitoring equipment.

• Product Specifications

• The function of the product

The primary function of the G2D9BEC board is to act as the first line of defense for the fetal monitor's power system. It distributes incoming AC power to the internal transformers and acts as a sacrificial component; if a power surge occurs, the fuses on this board will blow to save the expensive main processor and display boards from destruction.

Fault diagnosis

If you are repairing this Sunray SRF618B monitor, here are the following operating suggestions for this board:

1. Visual Inspection:

Hold the board up to the light and inspect the two glass-tube fuses. If the metal wire inside is broken, or the glass tube is blackened, the fuse has blown.

2. Multimeter Measurement:

Set the multimeter to the continuity setting.

Measure the two ends of each fuse separately. If the multimeter does not beep (infinite resistance), the fuse is damaged.
