Smart Power Meters
-
Smart Power Meters can help monitor the energy consumption and save on unnecessary costs. Featuring high accuracy, the ICP DAS USA Smart Power Meters can be applied to low, medium and high voltage to read and log energy consumption data of your equipment. They communicate over Modbus RTU, Modbus TCP, and CAN bus protocol, and it is easy to integrate with SCADA software for further control and analysis. The power meters are compact and low in cost, and come in a 3 phase, single phase, or multi-circuit measurement configuration. Our Smart Power Meters form the perfect base for any industrial power monitoring system, and our power meter concentrators log, store, and display live and historic power consumption data.

Isolation Transformers
-
Osborne’s Isolation Transformers are used to step-up, step-down and isolate voltages in single phase circuits. Isolation may be used to provide output circuit immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the input system. The isolation can allow separate grounds on both the input and output sides of the transformer. Osborne also designs with a range of electrostatic shielding to provide several levels of noise immunity.
