Powerbox releases new power supply for medical laser applications
Europe-based Powerbox has launched the SMM3000A80024C series, designed for high peak load medical laser applications, delivering 2.25kW repetitive peak power.
Powerbox, a European manufacturer of power supply solutions, has introduced a new product series, SMM3000A80024C, for demanding high peak load applications within the medical sector. The new power supply is designed to deliver 2.25kW of repetitive peak power to medical lasers with high efficiency, utilizing digital control and energy storage management techniques.
The SMM3000A80024C complies with medical safety standards, ensuring patient and operator safety when high voltages and energy levels are involved. It features a thermo-controlled cooling system for silent operation, addressing challenges with electromagnetic radiation and line disturbances inherent in high peak energy pulses used in medical lasers such as CO2 or Erbium YAG.
"A good device must deliver high energy levels during sub-millisecond pulses and be able to recharge for the next pulse," stated Patrick Le Fèvre, Powerbox Chief Marketing and Communication Officer. "By combining digital power and proprietary innovations, the SMM3000A80024C AC/DC capacitor charger effectively meets these job requirements and complies with the IEC60601-1 3rd edition medical safety standard."
The power supply offers a 2xMOOP primary-to-secondary and 2xMOPP to auxiliary output protection level. Its output voltage can be adjusted from zero to 800VDC (600VDC nominal) with a 5.5A output current at nominal, allowing adaptability for different capacitor banks and applications. An automatic current controller ensures safe power envelope limits, reducing capacitor aging and component stress for extended lifespan. A built-in microprocessor monitors charging status, end-of-charge levels, and protection warnings for over-temperature, over-voltage, and current.
To minimize line disturbances, the SMM3000A80024C includes a high-efficiency power factor corrector (PFC), soft-start circuitry, and filtering. It is housed in a six-sided shielded case and its fans are thermo-controlled to minimize audible noise. The unit also provides a 24VDC auxiliary output for laser controllers and interfaces, and can be connected in parallel for additional power.
