ecu.LV.3

Use existing low voltage controls:The ecu.LV.3 is designed specifically to monitor a three-phase load and control it via an existing control loop such as a sensor driven switch. It has to be connected to the power supply of the load being controlled with a four-wire cord. The unit also has three external CT sensor coils that have to be installed around the wiring for the circuit or load to be managed. The unit has two low voltage relays on board, which can control an existing low voltage switch such as a thermostat to shut off the load. This unit is ideal for controlling thermostat or time clock controlled devices such as pool pumps, air conditioners and water heaters. The unit can easily be installed by a qualified cabling technician and requires minimal electrical wiring.

The ecu.LV is designed to be installed in parallel to a load with no electrical connectivity wherein the high amperage, high voltage load does not run through the unit. It is powered by a 110V-250V (Line to Neutral) source which is converted into a 6V AC supply by an on-board, UL listed transformer. The unit is housed in a UL rated plastic case and contains a printed circuit board based monitoring, analysis and communication system. The unit has connectors where low voltage cables are attached to feed signals from external coils to take measurements from existing electrical wiring. There are also connectors for the on board relays to an external control loop such as a thermostat. The unit has an on-board FCC compliant radio to provide data via a wireless network and can also be paired wirelessly to other Akida hardware.

HOW THE ecu.LV.3 WORKS

Overview
The product uses three external current transformers (CT1, CT2 and CT3) to detect and monitor the electricity in the power cables of the existing circuit. The CT has to be appropriately selected from our range of calibrated CTs, based on the amperage rating of the circuit. The unit can be installed to monitor and control one three-phase electrical device that has a control loop to turn it off. The on board TARAS digital energy metering cards are able to provide real-time data on more than fifty parameters for electricity. This data is then relayed using RF wireless frequency of 2.4GHz to a remote Energy Gateway processor in an EMP or a Control Server. When the on-board, micro- relays receive the appropriate signal from the Energy Gateway Processor, they will open to turn the load off. The ecu.LV.3, when integrated into a system such as wattGAUGE will provide highly granular data on the power consumption and efficiency of electrical equipment/appliances in a building and help the user save on energy costs. With detailed data on the quality of the electrical power from the grid, maintenance schedules can be adjusted to maintain efficiency. Catastrophic failure of expensive, high-power equipment can be mitigated, by looking for anomalies in the data.
