ACREL Three-Phase Multifunction Power Meter
ACREL Three-Phase Multifunction Power Meter is a compact three-phase multifunction power meter for monitoring electrical parameters, energy consumption and power quality. It supports three-phase three-wire and four-wire systems, with measurements including voltage, current, power, power factor, frequency and energy. RS485 Modbus-RTU communication is provided as standard, with optional communication and monitoring functions available for different system requirements.
- APM510-D10: Configured for specific specialized low-current or miniature CT inputs (such as 5A/1.25mA or designated alternative sensor interfaces) rather than standard heavy-duty direct 5A terminals.
- APM510-D16: Configured for intermediate specialized sensor/CT ratio inputs (such as 100A/20mA secondary or specific loop configurations).
- APM510-D24: Configured for larger scaling profile inputs, commonly paired with specific flexible or standard medium-range unbundled CT ratings like 400A/100mA.
- APM510-D36: Configured for high-range scaling profile inputs, commonly matched with large-scale external CTs rated around 600A/100mA

Need additional option?
The ACREL Three-Phase Multifunction Power Meter is designed for monitoring and analysing electrical systems where a broad range of measurements are required from a single panel instrument.
It measures voltage, current, active power, reactive power, apparent power, power factor, frequency and energy, while also providing power quality information such as voltage and current harmonics from the 2nd to 63rd order. The meter supports both three-phase three-wire and three-phase four-wire electrical systems.
The ACREL Three-Phase Multifunction Power Meter includes a dot-matrix LCD with selectable Chinese and English display, while its communication capability allows measured information to be integrated into monitoring systems. Standard communication includes RS485 with Modbus-RTU and DL/T 645 protocols. Ethernet, Wi-Fi, LoRa, 4G and other communication options are available depending on the selected configuration.
How it works
- The meter receives voltage and current signals from the monitored three-phase electrical circuit, with current inputs rated for 1 A or 5 A configurations.
- It calculates electrical parameters such as voltage, current, power, power factor, frequency and accumulated energy.
- Power quality functions provide harmonic and other electrical system information, with some advanced functions available through the optional S configuration.
- Measured information can be viewed locally through the LCD display or communicated to a monitoring system through RS485 and optional network interfaces.
Why choose this product?
- Combines multiple electrical measurements in one panel-mounted instrument.
- Provides both local display and communication capabilities.
- Supports power quality monitoring in addition to conventional energy measurement.
- Offers configurable communication and measurement options for different monitoring requirements.
- Provides a compact 72 mm panel format for applications where panel space is limited.
Benefits
- Provides a central view of important three-phase electrical parameters.
- Helps operators identify changes in electrical load and power quality.
- Supports integration with energy monitoring and electrical management systems.
- Event and alarm recording can provide useful information when reviewing electrical system conditions.
- Optional functions allow the meter to be configured around the requirements of the monitoring system rather than using a fixed feature set.
