Description
ESP-34W APF Wall Mount – Active Harmonic Filter
35A -100A RMS Output Current Rating Per Module
Enersine APF measures and monitors the entire load current through external auxiliary coupling current sensing transformers (CT) mounted on the AC line, removes the fundamental frequency component and injects opposite phase harmonic current to cancel harmonic current in the electrical distribution system.
Like all Enersine APF Series, the compensation power electronics are packed in compact enclosed modules with forced air cooling designed for wall-mount installations where space is at a premium and harmonic mitigation current is high.
These ESP-34W power modules (PM) each 35ARMS, 60ARMS, 80ARMS, 90ARMS, 100ARMS rated and extendable, can be easily installed in small and confined areas, as well as the required “out of reach” locations. Each power module is fully HMI integrated with a built-in controller capable of compensating harmonics and phase displacements independently. Remote monitoring using building management system (BMS) via Modbus over RS485 RTU or Ethernet interface is available. Commissioning and maintenance can be easily performed with a laptop and Ethernet port.
High-density design allows these modules to be connected in parallel to achieve higher compensation power. This is particularly useful when considering future expansion or changes to the electrical networks which increases harmonic levels and requiring greater harmonic mitigation current.
