The is a high-precision, microprocessor-based control device designed for Automatic Power Factor Correction (APFC) in industrial electrical networks. It is specifically engineered to handle unbalanced three-phase loading conditions by utilizing 3-CT (current transformer) sensing, ensuring stable and efficient power factor correction even in complex grids. Core Technical Specifications
Standard power factor capacitors feature low impedance at high frequencies. When harmonics are present, capacitors act as sinks for these high-frequency currents, causing overheating, dielectric degradation, and premature failure. When configuring the BR5016 in harmonic-rich environments:

Conclusion The Epcos BR 5016 is emblematic of a generation of power-factor controllers that put operational reliability and maintainability first. While digital, networked controllers with adaptive control and harmonic compensation now lead the market, the BR 5016’s straightforward approach remains relevant where robustness, simplicity, and long service life are valued. For engineers maintaining legacy installations, understanding its operational logic, proper commissioning, and common failure modes ensures safe, effective reactive-power management without unnecessary replacement.
Reading: The reading stays at an unusual value (e.g., 0.10 or negative) despite heavy inductive loads. Action: This indicates a phase mismatch between the voltage inputs and the current transformer input. Refer to the manual's phase correction table to re-assign or re-wire the inputs.
is a 16-step microcontroller-based device designed for automatic reactive power compensation in unbalanced three-phase systems. It is particularly effective for industrial applications where precise power factor (cos φ) correction is required to reduce energy losses and improve power quality. Operating Voltage: 415 V AC (L-L), +20% to -30%, 50Hz. When harmonics are present, capacitors act as sinks
The device features a clear, illuminated and a menu-based interface. Settings are adjusted using 7 dedicated keys for programming and confirmation, providing straightforward, technician-friendly navigation. An RS232 interface is available for GSM connectivity with a dedicated modem, allowing for remote monitoring.
Proper installation is critical for both safety and accuracy. Always refer to the specific wiring diagrams found in the EPCOS Power Factor Controller BR 5016 Manual PDF.
The unit should be installed in a switchboard cutout. Ensure the ambient temperature does not exceed depending on the specific model environment. door cutout 138x138 mm
