277Vac rated power supplies deliver 40W-70W in miniature 2×4″ open frame
GLOBTEK GTM96700-BWWVV-F 40-70W open frame power supplies deliver an industrial grade version with up to 277Vac nominal rated input (305Vac max). With this configuration, a 277Vac supply is derived, (480Vac ÷√3=277Vac) measuring from one of the phases to the neutral connection which is popular for powering some types of industrial equipment. Voltage has been a popular option for powering some types of lighting, HVAC (heating and cooling) and other industrial applications. Product family provides global certifications for worldwide markets including the latest North American certification IEC62368-1 with a Limited power source (LPS) rating. A limited power source (LPS), as defined in IEC-60950-1, is a secondary circuit with an open circuit output voltage, VOC, not exceeding the SELV circuit limits of 42.4 VPEAK or 60Vdc.
