Product Description:
The EL3773 is an EtherCAT terminal designed for precise power measurement in industrial applications. It measures current and voltage values with a 16 bit resolution including sign, ensuring accurate monitoring. This terminal supports measuring voltage up to 500 V AC or 410 V DC, accommodating a wide range of power systems while having a current consumption of 200 mA on the E-bus, making it energy efficient. The device, supporting distributed clocks, is designed to operate effectively within a temperature range of 0 to 55°C, suitable for various industrial environments; approvals/markings include CE, UL.
The EL3773 enhances measurement capabilities with its oversampling feature and adjustable hardware filters. The oversampling factor is selectable from n = 1...100, allowing users to optimize the measurement accuracy based on the application's requirements through complex adjustments. Supporting both AC/DC measurement and optional single phase operation, this terminal provides adaptability for diverse power monitoring scenarios, supporting conversions with a minimum time of 100 μs, all channels simultaneously. The measured values include current (I1, I2, I3) and voltage as instantaneous values (oversampling). It functions through a measurement range that typically uses 100% of the nominal measuring range, see documentation.
Technically, the EL3773 has a measuring current up to max. 1 A for AC measurements and 1.5 A for DC measurements, when used with appropriate current transformers rated for 1 A AC and a measurement error/uncertainty of 0.5% relative to full scale value. It incorporates special features enhancing its application in industrial automation solutions because of its versatile interface and design, which supports precise monitoring and control, and it makes it an ideal option. This terminal provides reliable performance, which ensures accurate power management, and its selectable oversampling factors selectable between 1 to 100 with a conversion time of 100 μs and with an adjustable hardware filters.
