In addition to being completely modular, they're safe and fast to deploy to the field. Connect to the certus*EDGE* Edge Processing Unit (EPU) or the m410B Advanced Signal Processor for real-time access to a wider range of metrics for powerful analytic data today and beyond. #### Safe Because optical technology measures with light, it does not pass dangerous electrons. As a result, MICATU Advanced Sensors pose no violent failure or electrocution risks. #### Accurate Even in the most complex environments, MICATU Advanced Sensors maintain +/- 0.5% accuracy across the entire measurement range, regardless of applied voltage or current. #### Advanced The injection-molded HCEP housing is lightweight, durable, and non-conductive. The all-optical design keeps the sensor isolated from the current, ensuring high reliability and long life. #### Easy Install A typical three-phase system can be completed in about 3 hours. Voltage sensors are installed on any elbow, while the current ring sensor (model OUG225 only) can slide over either a cable or busbar. Fiber optic cables connect the sensors to the m410B Advanced Signal Processor. ## Our Products The MICATU Medium Voltage & Current Sensor System utilizes a 100% “all-optical” measurement platform for unparalleled accuracy and precision of both voltage and current across multiple voltage classes. Installation time for a typical three-phase system is less than three hours, resulting in significant deployment savings. All signals from the sensor are connected via optical fiber connections to a “plug & play” modular bay in the certus*EDGE* EPU or m410 processor that is fully ruggedized and scalable. ![REC220-3](https://www.micatu.com/hubfs/REC220-3.png) Combination Voltage and Current Optical Sensor ## OUG225 - **Voltage: **4kV to 27kV - **Nominal Current:** 10A to 1500A - **Weight:** 5.4 kg (12 lbs.)
