Voltage converter

   ATM-MS1 family converters are DC/DC impulse feeders appropriated to electric and electronic devices power supplies, where is required energy transformation with big efficiency as well as galvanic input – output circuit separating. Converter realizes vibrations and shocks requirements in accordance with PN-83/E-06122 standards - headed " Rolling stock. Requirements for electronic devices ". 

    High resistance on conductivity and high frequency radiation disturbing as well as on temporary high-energetistic over voltage makes, that voltage converters ATM-MS1 can be used in rolling stock and industry. Converter construction, leaning on modern semi-conductor devices, warrants long and reliable work. Indicators placed on front panel, allows on fast converter work conditions estimation.
