The ADE1201 application circuit accepts a wide range of input voltages from ±10VDC to ±300VDC, or 8Vrms to 240Vrms. The programmable wetting current and robust application circuit enable the device to meet stringent, system level electromagnetic capability (EMC) requirements. The ADE1201 includes an isoPower® integrated, isolated dc-to-dc converter that eliminates the need for an external isolated power supply. The iCoupler® chip scale transformer technology is used to isolate the logic signals between the high voltage, isolated side and the low voltage, nonisolated side of the digital input monitor. This technology creates a small form factor design that includes data and power isolation.
