Product Usage Instructions
User Interface
The product features a user-friendly interface with a 7-color touch screen display. This display allows users to set parameters, read event logs, download data to an SD card, view voltage and current waveforms, and observe frequency spectrum bar graphs. Closed
Loop Control
The active power filters support closed loop control for precise adjustment and correction of harmonic currents and power factor. The benefits of this control can be easily monitored on the display.
Open Loop Control
In addition to closed loop control, the product also offers open loop control for certain applications where precise adjustment is not required.
Harmonic and Power Factor Correction
The ESP actively corrects harmonic currents up to the 51st order and enhances inductive or capacitive power factor. These corrections can be verified on the display for monitoring purposes.
Frequently Asked Questions (FAQ)
- Q: How many phases does the ESP Active Power Filters support?
A: The ESP Active Power Filters support three-phase operation. - Q: What is the response time of the active filters?
A: The response time of the active filters is less than 1 ms.
Features
- Hot-swappable power modules that are easy to install make the architecture highly scalable.
- Their modularity, high current rating and the option of connecting them in parallel up to 2400A makes them versatile.
- ESP is available in two versions, 4 or 6 modules for 60A, 80A or 100A, which can also be used in a mixed configuration within the same system.
- Maximum performance with 3-level DSP technology.
- Their compact, high-power-density design optimises space.
- Multi-purpose: one model covers all three-phase systems (3-wire or 4-wire).
- Correction of all harmonics (up to the 51st) with a response time of less than 1 ms.
- No overload effect.
- Selective mode to select the harmonics to be corrected.
- Phase balancing of three-phase loads.
- Open loop or closed loop installation.
- A single control module manages up to 8 power modules.
- All parameters are under control via the 7” colour touch screen display that shows: voltage and current waveforms, frequency spectrum, parameters and events.
- Events and parameters can be downloaded to a removable SD card.
- Advanced communication: dry contacts (3 in and 1 out), USB, RS485 Modbus, RJ45 Ethernet, programmable email alarm.
- Multiple languages can be selected.
Open/closed loop control
User-friendly user interface
The 7” colour touch screen display can be used to set all parameters, read the event log file and download data to a removable SD card. It can also show the voltage and current waveforms, before and after enabling the ESP, along with a frequency spectrum bar graph.
Harmonic and PF correction that can be verified on the display
ESP not only actively corrects harmonic currents up to the 51st order, but also improves the inductive or capacitive power factor with a response time of less than 1 ms. The benefits can be seen easily on the display.
Specification
MAXIMUM ACTIVE FILTERING IN A MODULAR VERSION
ESP active filters with a modular structure can correct any type of harmonic contamination to protect the system from faults (e.g. on transformers, capacitors, etc.), while also improving the power factor.
