Atop Technologies' AD1024, AD1048, AD1072, AD1100, and AD1120 line of DIN rail power supplies are designed to support their Modbus gateways, Ethernet switches, media converters, and serial device servers. These power supplies have outputs of 24 V_DC and 48 V_DC with 24 W to 120 W of power with a wide input voltage of 100 V_AC to 240 V_AC and 120 V_DC to 370 V_DC at an input frequency of 47 Hz to 63 Hz. Hold-up time at full load at 230 V_AC is 20 ms (minimum). It provides overvoltage protection ranges from 27 V_DC to 30 V_DC, 40 V_DC, and 52 V_DC to 56 V_DC.
