Description

CPM-80 multifunction power analyzer provides high-accuracy measurement and is designed for single phase and three phase application. It includes 4 Digital inputs, 4 Relay outputs, and a RS-485 Modbus RTU Communication port. The user can choose one more communication port, and 2 Analog outputs for output expansion.

It provides measure voltage and current of the 2~63 harmonic, and it shows CO₂ emissions, which is suitable for power monitoring, management and analyze power quality. It has TOU (time-of-use) function and 4MB Flash memory capacity, allowing users to record data for a long time. It also has a software line adjustment function to reduce the on-site line adjustment work.

It has the functions of waveform capture and recording, power record, and event record, which can be used for multifunction power analyzer.

Features

■ Measuring 1P2W/1P3W/3P3W/3P4W system and the setting is programmable.

■ Measuring balance / unbalance loading system, including power parameters such as voltage, current, frequency, power factor, active power, reactive power, apparent power and energy.

■ CT input current can be set 1A or 5A by the user.

■ The number of sampling cycles is the number of cycles of the input frequency, and each cycle samples 256 points.

■ The large-size, high-brightness LCD is easy and clear to read even under direct sunlight.

■ Innovative meter AI calculation can perform automatic line adjustment (See Note).

■ Embedded 4MB non-volatile memory(NVM) which is with data and events recording function, can record for a long time.

■ Measuring power quality is optional, for recording voltage sag, voltage surge and current swell event which included the time stamp and setting value.

■ RS-485 Modbus RTU or Ethernet Modbus TCP is optional for the second communication.

■ Measuring voltage and current up to 63th individual harmonic, and can maintain power stability, and moreover, to avoid risk of equipment malfunctiion.

■ Standard with time of use (TOU) function, which can perform power consumption with differential statistics according to the electricity consumption period.

■ Standard with 4 sets of DI and 4 sets of relay output, or choose option with 8 sets of DI and 2 sets of AO for the control functions to facilitate on-site monitoring and alarm needs.

■ Standard with 1 set of RS-485 Modbus RTU, and it's optional for one more set of RS-485 or Ethernet interface (Modbus TCP).

■ CE, and FCC approved.

Note: Auto wiring function is conditional, please refer to operation manual.

Applications

■ Voltage swell and sag detection record

■ Power abnormal event record

■ Waveform capture and recording

■ Analysis of energy quality
