EOS LFMWLT150 Series Power Supply Board Analysis Report
Device Identification
The product examined in the visuals is an electronic AC/DC power supply (Power Supply Unit – PSU) board with an open frame structure, designed for use in medical or industrial devices. The device does not have a metal casing; components are mounted directly onto the printed circuit board (PCB).
Brand and Model
Upon detailed examination of the labels and prints on the visuals, the product’s brand and model information is clear:
- Brand: EOS (The stylized “EOS” logo and TM symbol are clearly visible on the label.)
- Model: LFMWLT150-1304-A-2 (Clearly written next to the “Model :” inscription on the main white label.)
- Compatible Device / Second Brand Reference: The label contains the inscription “WEINMANN NO : WM 27936”. This confirms that the product is a specially manufactured spare part for Weinmann branded medical devices (such as respirators, etc.).
Originality
The print quality of the labels on the product, logo details (UL, CE marks), fonts used, and industrial standards in component placement (design language specific to the EOS brand) indicate that the product is an original OEM part. There is no visual evidence suggesting it is an aftermarket or counterfeit product.
Areas of Use
This power supply board is used to convert mains electricity into low-voltage direct current that devices can use. Given the “WEINMANN” reference and the product range of the “EOS” brand, the primary area of use for this board is medical devices (such as ventilators, aspirators, or sleep apnea devices). Additionally, it can be used in industrial electronic devices with similar power requirements if its specifications are compatible. It should be considered as a spare part to replace a faulty power unit.
Quantity Information
Only 1 unit of the electronic power supply board is visible in the visuals. No external cables or accessories are present in the visuals.
General Condition
The product is in second-hand (used) part condition. However, its general appearance is clean. No significant dust accumulation or signs of wear are observed on the circuit board.
Physical Deformations
No physical deformations such as cracks, breaks, corner damage, or any surface deformation on the PCB (circuit board) were detected in the card’s physical structure. The mounting holes (screw sockets) appear intact.
Mechanical and Electronic Components
The product’s mechanical and electronic components have been analyzed as follows:
- Transformer and Coils: The copper windings wrapped with yellow insulation tape appear intact. The yellowish/white filling material (silicone-like structure) seen on the coils is a stabilizer applied during manufacturing to prevent vibration and noise; this is not a leak or a defect.
- Capacitors: No swelling or leakage is observed at the top of the large brown capacitor (PAG brand) in the input stage. The black electrolytic capacitors in the output stage are also physically in good condition.
- Sockets: The board features white input and output pin connectors. No bending or breakage is observed on the pins.
- Heatsinks: The aluminum heatsink blocks are firmly in place and show no bending.
- Solder Surface (Under PCB): Upon examining the underside of the board (Visual 3), the solders are seen to be professional (wave soldering), with no burn marks, amateur soldering interventions, or broken traces.
Label Information and Technical Codes
The data read from the labels on the device is as follows:
- Model Number: LFMWLT150-1304-A-2
- Production/Serial Code: E01-B-M725-5146 (Under the heading Build Code & S/N)
- Brand Reference: WEINMANN NO : WM 27936
- Transformer Top Label: CEL-22-LF000000007227, REV-A2, SA155, HP-OK
- Small Barcoded Label: 7CM0743L
- Power Ratings: The inscription “400 V” is legible on the capacitor, confirming it has a high-voltage input circuit.
Battery Status
The device does not contain an internal battery or battery cell. It is a power converter that operates with mains electricity.
Existing Faults and Risk Analysis
No findings that would render the device “non-functional” such as burnt components (blackening, soot), exploded capacitors, broken cable traces, or broken parts were observed in the visuals. The slight discoloration of factory adhesives on the coils over time is normal and does not pose a risk. However, the functionality of electronic boards cannot be 100% guaranteed based solely on visual inspection; its visual condition is “good”.
