Description

The APM-EMA series multi-circuit power meters are designed for multi-circuit power measurement needs. The Base Set features 18 single-phase or 6 three-phase inputs. Additionally, it can be expanded with an APM-MAA current input module (configurable), supporting 18 single-phase or 6 three-phase inputs. Up to five APM-MAA modules can be added, reaching 108 single-phase circuits or 36 three-phase circuits. This allows for diverse applications in various power circuits, significantly reducing costs.

It also features standard RS-485 Modbus RTU communication and demand flow measurement.

The main unit adopts a DIN Rail design for easy installation and maximum flexibility.

Features

■ Automatic Identification: APM-EMA automatically detects and records the setting parameters of APM-MAA expansion current modules.

■ Flexible Relocation (New): After module numbering is completed, the position can be arbitrarily changed, even if inserted into the wrong slot, greatly reducing maintenance difficulty!

■ Quick Lookup: A hidden button on the main unit displays the number of each expansion module with a single touch, making on-site wiring troubleshooting extremely convenient.

■ Built-in parallel expansion terminals on the side of the module automatically connect the power and communication ports of each module in parallel after installation, eliminating the need for additional bases Installation is extremely convenient and reliable, offering strong expandability and flexibility.

■ The front panel features a DIP switch for easy setting of communication parameters.

■ Equipped with LED indicators for power, system, and input, facilitating understanding of operating status and troubleshooting/maintenance.

■ Push-in direct insertion wiring eliminates the need for tools, saving wiring time and improving wiring safety and reliability.

■ The detachable terminal design allows for pre-assembly of cables and module replacement without removing wiring, simplifying maintenance.

■ Single-row connectors with wiring diagrams effectively reduce wiring errors and simplify maintenance troubleshooting.

■ The 35.0mm slim design saves significant space, allowing for installation in smaller cabinets and limited installation areas.

■ Isolation protection between power, communication, and I/O components effectively prevents damage to internal components, further protecting the host site.

■ It can be integrated with all products in the APM-IO series to meet diverse field measurement needs.

■ A wide voltage power supply design of 12~48VDC (±10%, 2.5W) provides greater flexibility and protection for the operating power supply.

■ A 17.5mm current input module (APM-MAA) is available as an option.

■ A utility model patent has been obtained in the Republic of China, and an invention patent application is pending.
