SMART SERIES
ERN 11206 / ERN 11214
EXCELLENT POWER FACTOR CONTROL, ANALYSIS AND CONTROL OF HARMONIC, SUITABLE FOR LV AND MV VOLTAGE SYSTEMS.
- Digital microprocessor controller designed for automatic power factor correction systems
- Relay outputs to connect or disconnect the capacitor banks
- Selectivity of capacitors – Using intelligent way (work hours and the required reactive power)
- During the control ERN 11214 continually checks the relay compensation section, when in detects a capacity loss or change in value, it temporarily disables the section under relevant setting.
- The temporarily disable section is anyway tested st regular intervals and when possible enable again control.
- Reliable power factor control even in presence of high current and/or voltage harmonics content.
- Current and voltage harmonic analysis up to 19 order.
- In case an abnormal situation in the system (calculated from THD and CHL measurements) the controller disconnects all compensation sections for preventing their damage.
- Display 4 digits 7 segment LED.
- Measure and display the following parameters. Information shown on the numeric display are divided into 3 main data group :
- Instantaneous power system values measured such as power factor, active power, reactive power, apparent power, current, voltage, THDI, THDV and capacitors CHL, frequency, power.
- Controller parameters target power factor, control period, reconnection delay time, total recorded connected times, numbers of connections of each compensation bank, etc.
- Test and error messages.
- No-voltage release protection.
- Capacitor overload and panel overheating protection.
- Suitable for co-generation systems (4 quadrant operation)
- 3 way parameter set-up automatic, manual, PC.
- RS232 or RS485 communication interface for st-up and automatic testing with Personal Computer.
- Adjustable reconnections time delay.
- Specila Voltage Optional
- Voltage measurement input and second metering rate input – suitable for MV capacitors banks.
