FWM120/FWM150 Series : Medical-Grade 120W & 150W Waterproof Desktop External Power Supplies

The FWM120 (96W–120W) and FWM150 (132W–150W) series introduced by FranMar are high-performance, high-protection AC/DC medical-grade waterproof desktop external power supplies (Medical Waterproof Desktop Adapters) specifically designed for demanding medical devices. In modern healthcare and clinical environments, the stability of medical equipment directly impacts patient safety and the quality of diagnosis and treatment; this series serves as the critical core for enhancing system reliability.

These two series feature a fully enclosed 94V-0 flame-retardant polycarbonate (PC) housing that complies with IEC 60601-1 3rd edition (including IEC 60601-1-11 for home healthcare environments). With an ingress protection rating of up to IP54, they effectively safeguard against liquid splashes, chemical disinfectant wipes, and dust penetration commonly found in medical settings. This ensures long-term, stable operation in damp, corrosive environments or medical fields where frequent cleaning is required.

Furthermore, this series offers four types of AC inlets—IEC320 C14, C6, C8, and C18—allowing compatibility with standard power cords worldwide. End customers can seamlessly transition between target markets without modifying the power supply unit itself, significantly reducing stocking and SKU management costs for global deployment. Supporting a wide input voltage range of 80–264 VAC (frequency 47–63 Hz), it perfectly adapts to power grids across North America (115V), Europe (230V), and Asia. It stands as a premium medical power solution combining electrical safety, extreme durability, and universal compatibility.

• IP54 High Protection Rating (Fully Enclosed Design):
  • Dust Protection (Digit 5): Features an advanced dust-accumulation prevention mechanism that effectively blocks harmful dust and particles from penetrating the core circuitry during ward use, home healthcare, and clinical operations.
    
  • Water Resistance (Digit 4): Certified through comprehensive splash-proof testing; liquid splashes from any angle, physiological saline spills, or frequent wiping with medical alcohol and chemical disinfectants will not compromise the internal electrical structure.
• Fanless Silent Operation & Fully Flame-Retardant Design: Utilizes a high-density 94V-0 flame-retardant enclosure with natural convection cooling. Zero-noise operation makes it ideal for environments with strict silence requirements, such as hospital wards and operating rooms.
  
• 5,000m High-Altitude Operation: Optimized with increased internal electrical clearance, supporting the stable operation of equipment in high-altitude remote medical stations, ambulances, and plateau environments.
  
• 2 MOPP (Means of Patient Protection): Provides a high isolation voltage of up to 4,000 VAC from input to output. Both Class I and Class II models fully comply with IEC 60601-1-11, ensuring absolute safety for both healthcare professionals and patients.
  
• Low Leakage Current Control: Earth Leakage Current is < 220\ μA and Touch Current is < 100μA, guaranteeing maximum safety for clinical applications.
  
• Wide Voltage Input & Built-in Active PFC: Supports a full universal input grid range of 80–264 VAC (47–63 Hz). Features built-in Active Power Factor Correction (Active PFC), achieving a typical power factor as high as 0.98 at 115 VAC.
  
• Comprehensive Circuit Protection Mechanisms: Built-in protection includes Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP with auto-recovery), and Over Temperature Protection (OTP with latching/reboot).
  
• Diverse AC Inlet Specifications & Minimal Stocking Costs: Offers four international standard AC input options (C14, C18, C6, C8). This allows a single unit to flexibly adapt to various global target markets, drastically streamlining SKU inventory.

Combining an IP54 ingress protection rating with 2 MOPP high-isolation safety features, the FWM120 / FWM150 series is perfectly suited for the following high-end medical equipment fields:

• Home Healthcare Equipment: Sleep apnea respirators (CPAP/Ventilators), home hemodialysis machines (dialysis equipment), mobile motorized nursing beds, and smart medical wheelchairs.
  
• Clinical Monitoring & Diagnostic Equipment: Hospital patient monitors, portable diagnostic ultrasound systems, electrocardiographs (ECG/EKG), and blood pathology analyzers.
  
• Operating Room & Laboratory Waterproof Environments: Endoscopic imaging systems susceptible to saline or chemical splashes in operating rooms, dedicated power supplies for dental chairs, low-temperature centrifuges, and medical liquid agitation/mixing equipment.
  
• Rehabilitation & Physical Therapy Devices: Far-infrared thermotherapy devices, electrical muscle stimulators (EMS), and exoskeleton rehabilitation assistive devices.

Q1: Why do medical power supplies need an IP54 rating? What are the practical benefits in a clinical setting?
A: In medical environments, power supplies are often placed on the floor or at the bottom of equipment carts, making them highly susceptible to spilled IV fluids, physiological saline, bodily fluids, or strong chemical disinfectants. The IP54 rating (where "5" denotes protection against harmful dust accumulation and "4" indicates splash resistance) ensures that liquid splashed from any angle onto the enclosure will not penetrate the interior. This completely eliminates the risk of short circuits and equipment downtime caused by fluid conductivity, while significantly extending the lifespan of devices in home healthcare and high-intensity clinical environments.

Q2: What is 2 MOPP protection? What does it mean for our equipment compliance?
A: 2 MOPP stands for Two Means of Patient Protection, which is the most stringent level of safety protection defined under the IEC 60601-1 medical electrical safety standard. The FWM120/150 series features an ultra-high isolation insulation voltage of 4,000 VAC between the input and output stages. This means that even in the event of a severe internal power supply failure, it guarantees 100% protection for the patient against hazardous electrical shocks from leakage current. It is an essential specification for instruments to successfully pass medical device registrations such as TFDA, FDA, and CE-MDR.

Q3: How do we select the model suffix (e.g., "-x") for the FWM120 and FWM150 series?
A: The variable "-x" in the model number represents the configuration of the AC inlet socket. Procurement and R&D engineers can flexibly select the appropriate option based on the system's grounding design (Class I or Class II):
4 = IEC 320 C14 (3-pin, grounded; ideal for most clinical diagnostic equipment)
5 = IEC 320 C18 (2-pin, ungrounded; the preferred choice for Class II home healthcare)
6 = IEC 320 C6 (Cloverleaf/Mickey Mouse type, 3-pin, compact footprint; ideal for mobile medical carts)
8 = IEC 320 C8 (2-pin; suitable for lightweight, small-scale instruments with no grounding requirements)

Q4: How does this power supply help procurement and operations decision-makers "reduce global deployment costs"?
A: Previously, medical devices exported to different countries often required re-evaluating power supplies with different AC inlets, which increased inventory complexity and SKU counts. This series from FranMar offers four optional AC inlets (C14, C6, C8, C18) combined with an ultra-wide universal input voltage range of 80–264 VAC. As a result, you only need to change the external power cord to ship the exact same medical product to North America (115V), Europe (230V), or Asia. This achieves a "one unit fits global markets" strategy, drastically streamlining safety stock and inventory costs.

Q5: Does the product support 5,000-meter high-altitude operation? How does this affect structural design?
A: Yes. Both the FWM120 and FWM150 series have passed high-altitude barometric and insulation testing, supporting stable operation at altitudes up to 5,000 meters. At high altitudes, the thin air causes the insulation and voltage-withstand capabilities of traditional power supplies to degrade. FranMar has proactively optimized the internal circuit design by increasing the electrical clearance. This allows R&D engineers designing high-end mobile ambulance instruments or plateau medical station equipment to bypass the need to redesign the enclosure structure due to high-altitude insulation degradation.
