Small size
Simplify the frame to reduce the depth of the entire controller, simplifying the installation design so that the entire controller can be installed on a very compact switchboard and used.
Fixed method
The metal screw fixes the entire power factor controller to ensure long-term use of the firmness and reliability.
High degree of protection
The front and rear seals of the controller ensure that the entire controller achieves IP54 protection.
With the basic controller function, you can easily extend the use of the EXP series module
Extensible modules:
- The relay output increases the number of steps
- optically isolated static output, the same applies to dynamic correction
- Capacitor protection
- switch, analog input and output
- Optically isolated RS232 port
- Optocoupled RS485 port
- Optical isolation Ethernet interface with network server function
- Optically isolated Profibus-DP port
- GPRS / GSM module
- Data logging and time recording module (RTC).
Master-slave design
The SIEG-PFC controller can control the output of other analog controllers (except for its own steps). In this way, a master-slave architecture can be formed, and the main control can control up to eight steps from the controller.
Multilingual graphics and text
The controller provides 10 languages ​​to view waveform trend text and bar charts. Languages ​​include: Italian, English, Spanish, French German, Czech, Polish, Russian, Portuguese. And can be customized according to customer needs.
Suitable for dynamic power factor compensation
By installing the EXP10 01 static output module, this controller can be used in dynamic power factor compensation systems where the reactive power is rapidly changing over time. The same use of the relay output built into the controller can produce a relay that is driven by conventional relays and dynamics Type of correction step consisting of a mixed system.
Network server function
By moving out of the EXP10 13 Ethernet module, most of the measured data acquired by the controller can be viewed on the common Web client, and on the computer, you can get data via the java platform and do not need to install any Extra computer software.
Capacitor protection
By adding the EXP1016 expansion module, the Sieg-PFC controller can install capacitive protection to provide additional security for the safe operation of the controller. This module can measure the harmonic current value and the current temperature of the capacitor, in order to detect the problems in any one step.
3 current input
Independent power factor corrections can be made for each step.
Analyze all the electrical parameters in the network instrument.
GSM / GPRS module
Installing and installing a GSM / GPRS module automatically by installing the EXP10 15 expansion module controller simplifies the installation and routing of the controller. Enable and insert a data SIM card alarm or event SMS SMS and mail. This module can be sent from the controller to the FTP server.
