Ecosine active sync series is next-gen for harmonic filters

Electromagnetic compatibility and power quality specialist, the Schaffner Group, has launched the sync module SYNC300A for the ecosine active sync series of modular and compact active harmonic filters

The sync module for ecosine active sync series mitigates excessive harmonics with an evolutionary smart modular product concept with control options. The Sync300A sync module is scalable in terms of mitigation current and the filter’s capability, smart load management and efficiency, redundancy, reliability and connectivity.

The optional Sync300A sync module completes the ecosine active sync series FN 3530/31/40/41, FN 3532/42 and FN 3545. Based on the same modular compact concept, the Sync300A additionally offers flexibility for open or closed loop current control. Regardless of whether the current transducers are installed on grid or load side; with the sync module there is only one CT connection point to the filter’s system.

The sync module facilitates the scalability and extensibility of the filter system. The Sync300A can connect and manage up to five FN 3530 (three-wire) or FN 3540 (four-wire) power modules, building a system filter up to 300A. Additionally by connecting four sync modules together a mitigation current of up to 1200A can be reached as one active harmonic filter system with one CT connection point.

The sync module allows smart load management. The intelligent control of the sync module senses the real time demand for compensation current in the ecosine active sync filters and adjusts the usage of the installed power modules. In periods of lower mitigation current demand, the Sync300A can de-rate power modules or put them on standby in order to reduce energy consumption and increase the lifetime of components.

Smart control of the sync module and the modular concept of the ecosine active sync family allows redundancy, ensuring continuity of operation and minimising shutdown time for customer applications. Communication options include PLC or Ethernet TCP/IP.

The sync module can be installed on a wall, inside a Schaffner cabinet or in a 19-inch rack. The FN3545 series ecosine active sync cabinets from Schaffner with pre-integrated sync module Sync300A, offer customers a standalone module.

By deploying ecosine active sync filters FN 3530/31/40/41, FN 3532/42 and FN 3545 from Schaffner it is possible to achieve a total harmonic distortion (THDi) of five per cent or less, especially for mixed load and dynamic load profiles. They also guarantee compliance with the toughest requirements of IEEE-519 and other stringent international power quality standards.
