I. Industry Trends: The Necessity of USB-C Adoption in Medical Equipment
Driven by EU regulations and the rapid digitalization of healthcare, electronic products and medical devices are undergoing a comprehensive transition to the USB-C interface. For devices such as tablets and mobile medical displays, providing stable power that complies with USB-C PD specifications and 2 x MOPP (Means of Patient Protection) standards has become critical for precision instruments like ECG machines and patient monitors. In clinical environments, ensuring the safety and reliability of the power supply remains the highest priority.

II. Franmar Solution: FHMC Series High-Efficiency Medical Power Supplies
In response to these evolving needs, Franmar has launched the FHMC Series. This series not only meets the rapid charging requirements of high-end information technology equipment (IEC/UL/EN 62368-1) but has also obtained IEC/EN/ANSI/CAN 60601-1 medical certification, ensuring electromagnetic compatibility (EMC) and patient safety in critical healthcare settings.

Advanced Technology: Utilizing cutting-edge components and GaN (Gallium Nitride) technology, the FHMC series delivers high power ranging from 60W to 140W within a compact, handheld size, fully compliant with USB-C PD 3.1/3.0 protocols.

Ideal for Extreme Environments: Specifically designed for space-constrained applications such as Telemedicine Carts and ambulances, the FHMC series significantly reduces heat dissipation, saves space, and extends equipment lifespan.

High Reliability: Featuring low leakage current (< 100µA) and a MTBF (Mean Time Between Failures) of over 100,000 hours, it supports stable, 24/7 continuous operation.

III. Frequently Asked Questions (FAQ)
Q1: Why must medical devices transitioning to USB-C comply with 2 x MOPP patient protection standards? As medical digitalization advances, tablets and displays are increasingly used in clinical proximity to patients. Power supplies like the Franmar FHMC series, which meet 2 x MOPP and IEC 60601-1 standards, ensure extremely low leakage current (< 100µA). This eliminates the risk of electric shock at the source—a non-negotiable safety requirement for ambulances and precision diagnostic environments.

Q2: How does GaN (Gallium Nitride) technology address space and heat issues in Telemedicine Carts? The Franmar FHMC series leverages advanced GaN technology to deliver up to 140W of power while drastically reducing the adapter's physical footprint. Its high conversion efficiency significantly lowers heat generation, which not only conserves valuable space within telemedicine carts but also protects sensitive peripheral medical instruments from thermal stress, ensuring reliable 24/7 operation.

Q3: How does the Franmar FHMC series satisfy the dual requirements of high-end ICT and medical equipment? The FHMC series possesses ""cross-domain"" certification, meeting both IEC 62368-1 (ICT standards) and major global medical certifications (IEC/EN/ANSI/CAN 60601-1). Combined with USB-C PD 3.1 technology, it can simultaneously support fast charging for high-performance medical workstations while providing the stable, clean power required by precision patient monitors.

Yes, FranMar's class I (C14 & C6 AC inlet) adapter is designed based on isolation concept, it will be no problem that the output ground (GND) and frame ground (FG) is the same point in your system. However, EMI may be affected by this connection.

When installing the power supply, both input and output ends need to be connected by wire. The following points need to be considered in selecting wires.

(1) Current rating : if the current rating is insufficient, the wire temperature will be too high or even burned

(2) Voltage drop : the wire itself has impedance, when the current flows, it will cause voltage drop. If the voltage drop is too high, it will cause the voltage at the load end to be too low, which may cause the load to fail to work.

(3) Noise : it can be a problem for wires, especially when high frequency signals travel long distances, using shielded wires may help eliminate noise and EMI disruptions.

The switching power supply will appear a high pulse current at the moment when power supply is powered on. After the product is started, it will resume the normal current input. This phenomenon will occur every time when input power into the PSU which is a normal and will not cause damage to the power supply. However, it is not recommended to turn on and off the power supply continuously.

PFC is a circuit which is to improve power conversion efficiency. Under this circuit, the ratio of apparent power to real power can be reduced. E.g. Without the PFC, the power factor is around 0.4~0.6, power plant needs to generate more than 2WVA electricity to fulfill 1W usage. Same condition, the power with PFC circuit (power factor is 0.95), the power plant only needs to generate more than 1.06VA electricity. Therefore, choose an active PFC power supply can contribute to energy saving and environmental protection.

Voltage is the electric potential in a circuit that gives potential for current to flow. However, it doesn't mean that the circuit has current while voltage is present in a circuit. Voltage is the force that pushes electrons through the circuit when the path is closed for current to flow. Current is only present when there is a closed, completed path for current to exist.

Current is the rate at which electrons flow past a point in a complete electrical circuit.

Frequency is typically used to describe electrical equipment operation. It is the rate at which current changes direction per second.
