ESP 400, ESP 600 Active Power Filters
Product Information:
The Active Power Filters (ESP) are designed for various
applications including energy distribution, transportation,
industrial applications, and electro-medical equipment. They
feature a response time of less than 1 ms and can operate in both
open and closed loop control modes. The filters are equipped with
external CTs for accurate current measurement. The user-friendly
user interface includes a 7 color touch screen display that allows
users to set parameters, read event logs, and download data to an
SD card. It also provides voltage and current waveforms, frequency
spectrum bar graph, and harmonic and power factor correction
verification.
The ESP active filters come in two models: ESP 400 and ESP 600.
They have a modular structure that allows for maximum active
filtering. The filters can correct any type of harmonic
contamination to protect the system from faults and improve the
power factor. They operate at a rated voltage of 400V or 480V with
three-phase connection. Harmonic correction is provided from the
2nd to the 51st order, and power factor correction is both
capacitive and inductive. The filters support load balancing and
have a wide operating temperature range.
Product Usage Instructions:
- Connect the external CTs (xxxx/1 or xxxx/5) to accurately
measure the current. - Install the active power filter in parallel with the system to
be protected. - Use the user-friendly user interface on the 7 color touch
screen display to set parameters, read event logs, and download
data to an SD card. - To verify harmonic and power factor correction, check the
display for waveform graphs and frequency spectrum bar graph. - Ensure proper load balancing by monitoring the voltage and
current waveforms before and after enabling the ESP. - For closed loop control, select the appropriate control mode
using the user interface. - Monitor the system’s performance and adjust parameters as
needed using the touch screen display. - Ensure proper installation by following the installation
guidelines provided in the user manual.

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.

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.
