Product Description:


The HC6000 is a cost efficient, multi-function Power Meter that replaces conventional analog or digital instruments and switches.The HC 6000 is specifically designed to be compatible with the world’s 2 most widely used DIN standard panel instruments (It fits the DIN 92 x 92 mm panel cutout holes) and is easily and efficiently hooked upr. It’s hardware is suitable for either 1 phase 2 wires, 1 phase 3 wires, 3 phase 3 wire or 3 phase 4 wires networks. HC6000 can communicate via serial port (RS-485 or RS-232), and Modbus® . It’s internal software provides a simple yet practical solution to energy management for factories, small and large Plants.Te VFD monitor displays V, A, VA, W,Var, WH, etc. It also displays maximum and minimum values, maximum demand control, time stamping and more than 90 power and energy parameters.


  • Factory & Building Automation (FA & BA)The HC 6000 is developed for factory and building automation(FA & BA) applications. It can meter the power and energyparameters of a wide range of industrial power distribution systems and AC switch-gears.
  • PLC Modbus CompatibleThe Modbus® communications protocol allows information anddata to be efficiently transferred between HC 6000 andmodicon programmable logic controllers (PLC) or other thirdparty Modbus® compatible monitoring and control systems.The HC 6000 can also establish a monitoring system just simply adopt an IPC-based centralized master display software.(RTU mode Modbus® protocol with default baud rate 9600 bps, none parity, 8 data bit.)
  • Built-in Real Time Clock (RTC)HC 6000 appends a time stamp for all maximum and minimum energymeasurements records. Ideal for identifying abnormal events and easy record accessibility. It also provides a demand-control timeperiod 15 / 30 minutes for maximum power demand controlof utility load shedding.
  • MemoryAll of the meter status setting and energy data are retainedin in a non-volatile memory . HC 6000 records includesthe watt-hour measured, maximumdemand values, date and time, PT and CT ratio andsystem configuration
  • Field ProgrammabilityEasily set CT and PTratios, Modbus® address, communication baud rate, parity,meter’s display, etc. programmed by front panel orby PC via RS-485 / RS-232.
  • Accuracy up to 0.15%Hsiang Cheng’s conversion, sampling and softwarecompensation technology provide the HC6000with the high accuracy required for today’s needs. Voltage and current accuracy up to 0.15% and power to0.25%.
  • Comprehensive CommunicationModbus® ( compatible withthe modicon system ).RS-485 / RS-232 Modbus® communication between modicon programmable logic controllers (PLC), RTUPower SCADA system and DCS systems
