Acuvim KL Power Meter with RS-485 MODBUS Communications
Acuvim-L Series power meters are
for power metering and monitoring at electrical panels and energy
consuming devices or systems. They are also great for non-revenue
sub-metering applications. Measuring all the key electrical parameters,
these power meters offer great value.
The Acuvim KL version features a single RS485 MODBUS communications port which allows you to use AccuEnergy's free Acuview energy monitoring and reporting software.
The Acuvim L comes in 6 different models, allowing you to choose the features that are right for you, see the Grid below for the various models:

Applications
- Metering of distribution feeders, transformers, generators, capacitor banks and motors
- Medium and low voltage systems
- Commercial, industrial, utility
- Power quality analysis
Measurements
All Acuvim-L power meters can be used on any single or three phase electrical system up to 600V AC. They measure volts, amps, frequency, power (apparent, active, reactive) & energy, power factor, THD and individual harmonics on both voltage and current to the 15th harmonic.Communications
- Acuvim AL is manual read meter only, with no remote communication options
- Acuvim BL includes a digital pulse output for kWh or kvarh. Pulse rate and width can be set. Also comes with an Alarm output.
- Acuvim CL includes BL capability and communications through MODBUS RTU via a built-in RS485 serial port.
- Acuvim CL-M is a DIN Rail mount version, with all the features, but no display. This lower cost device is great if manual meter reading is not required.
- Acuvim DL has 4 Digital Inputs, 2 Digital Outputs, 1 RS485 port with Modbus RTU protocol and Load Run Time.
- Acuvim EL has Load Run Time (TOU) and 1 RS485 port with Modbus RTU protocol.
- Acuvim EL-M comes with all the EL features, but no display. This lower cost device is great if manual meter reading is not required.
- Acuvim KL is an excellent, low cost meter for basic power (kW, kVA, kVAr and Energy (kWh, kVAh, kVArh) and Load Run Time. Perfect for basic sub-metering applications.
Warranty & Approvals
Acuvim-L meters are UL/ULc approved for use throughout North America and come with a 5 Year manufacturer's warranty.
