EKM Omnimeter Mini v.4 (beta) – Pulse Counting, Relay Controlling, Universal Smart Electric Meter

This miniaturized PCB mounted universal kWh meter can be used on nearly any electrical system in common use and can also count pulses from up to 3 pulse-output devices, as well as control an external relay or valve. ~section 2~ Description: Very small, PCB, universal, Pulse Counting, Relay Controlling, Smart Meter Features: 45mm x 50mm x 20mm high.  Pulse Counting and Relay Controls Voltage: 120 volts, 120/240 volts, 120/208 volts, 230 volts, 277 volts, 480 volts Amperage: Up to 5000 amps Type: External CT, 50 or 60 Hz System: Single-Phase, 3-Ph. 3-Wire, or 3-Ph. 4-wire Data: Smart Meter v.4 RS-485 Communications Model: EKM-Omnimeter Mini v.4 The Omnimeter Mini v.4 is a miniaturized version of our most advanced universal smart meters, it is designed to be embedded into EV chargers, inverters, electrical appliances, etc.  It can be soldered to your PCB using the castellated edges or mounted to your PCB using header pins. The Mini v.4 has the ability to count pulses from up to 3 separate pulse-output devices, and control 1 x external relay. This is truly the one meter to meet all of your metering needs! Please Note:  This meter does not come with a protective enclosure (be careful!), it is just the bare PCB that you see in the photos.  It is also 12 volt DC powered, unlike our other Omnimeter models which are powered by the AC voltage references.  But it will still have the high voltage connections from the voltage reference wires, so there will be high voltage present on the PCB! This is a revenue-grade universal kWh meter. It can meter systems ranging from single-phase 120V 2-wire or single phase 120/240V 3-wire, 120V to 480 volts, or 3-phase 3-wire 120 to 415 volts or 3-phase 4-wire 120 to 480V, 50/60Hz. It Supports CTs from 100A to 5000A. Accurate to 0.5% (Class 0.5) The v.4 Omnimeters can also count the pulses from up to 3 different pulse output devices, as is explained in this video. These could be pulses from our Pulse Output Water and Gas Meters or from any other non-powered dry contact pulse output device. The real-time state of the three Inputs can also be polled remotely by our EKM Push3 gateway. The Omnimeter data will return a High (open) or Low (closed) state for each pin in real-time (use this for sensing switch states, open or closed doors, etc). The Mini v.4 also include 1 x controllable relay output. This output can be controlled via RS-485, either locally via our EKM Dash software, or remotely online via our Push3 gateway. You can set the outputs to be high or low to drive an external relay. The Relay Control Outputs can continuously provide up to 50 mA at 12 volts DC each. Control the EKM-Switch120 directly, or control lights, motors, entire buildings, implement Demand Response, Load Shedding, etc. via relay control. The Relay Control Output can also be set to only go ON or OFF from 1 to 9999 seconds. The real-time state of the outputs can also be polled via RS485. The outputs can also be used to power an external device (Wireless 485Bee Module, sensors, etc). Relays can be controlled online when reading the meter with the EKM Push3 data system, or locally when reading the meter with a USB Converter. The only metering system that is commonly used that this meter will NOT support is 3-phase 3-wire 480 volts. You would need an Omnimeter HV v.4 for this system. This meter uses our full range of compact Current Transformers (it cannot meter electricity without at least one). The CT ratio can be set internally to work with up to 5000 amp CTs (no multiplier needed).  We can also produce through-hole mounted CTs which would solder directly to your PCB and be connected to the Omnimeter Mini v.4 with traces, please let us know if you are interested. Use 1 CT for 120 volt single phase North American, or 230 volt 2-wire foreign systems Use 2 CTs for 120/240 volt single phase systems Use 2 CTs for 3-phase 3-wire systems (no neutral) Use 3 CTs for 3-phase 4-wire system These meters are also supported by our EKM Push3 data system. This is our cloud-based, plug-and-play, meter data solution. We recommend the Push3 for most remote reading applications that use our Omnimeter models. Push3 users can also take advantage of Encompass.io, which is our free online dashboard and meter management, dashboard, and billing suite. If you order the Omnimeter Mini v.4 from our website, we will ship it with the LCD screen.  But if you order large quantities to be integrated into your product from the factory you can choose: To exclude the LCD screen The length of the ribbon cable to the LCD screen Bare castellated edges, terminal blocks, header pins out the bottom, or header pins out the top, female sockets out the bottom, female sockets out the top, etc. To include or exclude the RTC clock battery The Omnimeter Mini v.4 also can be set to communicate using a modbus protocol, let us know if this is something that interests you. Encompass.io Encompass.io is our free online meter management platform for monitoring data, managing meters, generating bills, and more. It is designed specifically for people who are remotely reading their meters via the Push3 system. This platform can be used to visualize data on customizable dashboards, visualize cost, monitor trends, group meters, and a lot more. Each meter and meter group in Encompass can also be set up to email you, and/or your tenant, PDF bills. Here is a sample PDF electric bill: EKM Widget The EKM Widget offers another option for quickly seeing your meter data online for Push3 users. It is also easy to save and share your Widget setting once you have it setup how you want. Here is an example: EKM Dash Our Omnimeters are also fully supported by our free, remote reading, EKM Dash software. If you want to read your Omnimeter on a computer locally, without the EKM Push3 system, then this software is what you would use. You will also need an EKM Blink USB Converter in order to do so.
