Schneider Electric A9MEM3335

The iEM3335 energy meter is designed to operate within diverse network configurations, measuring active and reactive energy, power, voltage, and current. It supports a line-rated current of up to 125 A through direct connection and is compatible with single-phase, three-phase, and three-phase with neutral setups. The meter operates efficiently on supply voltages ranging from 100 to 277 VAC or 173 to 480 VAC, making it versatile for various installations.

Equipped with a communication protocol of M-Bus via screw terminals, it allows for flexible integration into existing systems. The meter includes one programmable digital input and one programmable digital output, which can function as a pulsed output. Notably, it features a four-quadrant energy measurement capability and supports up to four tariff schedules.

Accuracy is maintained with classes defined as Class 1 for active energy per IEC 62053-21 and IEC 61557-12, as well as Class B according to EN 50470-3. Local indications include an LED power-on indicator, a flashing yellow LED for accuracy checks, and overload alarms, enhancing user interaction.

In terms of physical specifications, the meter measures 126 mm in width, 69 mm in depth, and 103 mm in height, with a weight of 260 g. It operates effectively in ambient temperatures ranging from -25 to 55 °C and can withstand storage conditions between -40 to 85 °C. The device adheres to numerous standards, including IEC 61010-1 for safety and EN 61557-12 for power monitoring,...
