Origins and context
Enter the primary current value of your CT (e.g., if using a 1000/5A CT, set the primary value to 1000 ). Step 3: Defining Target Power Factor (
The BR5016 is designed for panel flush-mounting. Ensure adequate clearance at the rear of the enclosure for wiring harnesses and ventilation. Wiring Configuration
The EPCOS BR5016 (often branded under TDK-Epcos) is a digital power factor controller used in electrical engineering to optimize energy efficiency in industrial power grids. It regulates the connection and disconnection of capacitor banks to correct the power factor (cos φ), reducing reactive power consumption and avoiding penalties from utility companies.
Connect the measuring voltage terminals to the phases (e.g., L2 and L3). Ensure the voltage matches the device variant specifications. --- Epcos Power Factor Controller Br 5016 Manual Pdf
Program the reactive power output (in kVAR) for each individual step connected to the 16 available relays. For example, if Step 1 is a 10 kVAR capacitor and Step 2 is 20 kVAR, input these specific values so the intelligent switching algorithm can select optimal combinations. 5. Maintenance, Troubleshooting, and Error Codes
The monitored line voltage has crossed the pre-programmed safety thresholds. Action: Verify network voltage stability and adjust the controller's threshold settings if permissible.
Navigate through the menu structure to configure the following essential settings:
Modern industrial facilities are filled with non-linear loads such as Variable Frequency Drives (VFDs), LED lighting, and uninterruptible power supplies (UPS). These loads inject harmonic currents into the network, distorting the voltage waveform. Origins and context Enter the primary current value
| Display Code | Meaning | Action per Manual | | :--- | :--- | :--- | | AL. 1 | Undercurrent | Load current below 5% of CT rating. Check if main breaker is open. | | AL. 2 | Overvoltage | Voltage > 110% of nominal. Check grid stability or tap changer. | | AL. 3 | Undervoltage | Voltage < 80% of nominal. Brownout condition. | | AL. 4 | Over-temperature | Internal temperature > 70°C. Clean air vents or reduce switching cycles. | | AL. 7 | THD overload | Harmonic distortion > 10%. Install a detuned reactor or filter. | | c-- flashing | Wrong target power factor | The actual Cos φ is too capacitive. Reduce capacitor steps. |
Allows setting a second target power factor, which can be triggered via an external digital input during periods when a backup generator is running. Troubleshooting and Fault Codes
Connect the independent control supply voltage to the designated power terminals. Ensure proper fuse protection (typically a 2A or 6A slow-blow fuse). Current Transformer (CT) Connection: Connect the
Power factor correction (PFC) is essential for maximizing electrical efficiency and reducing utility penalties. The is a highly reliable device designed to automate this process. It monitors power quality and switches capacitor steps to maintain an optimal power factor. Wiring Configuration The EPCOS BR5016 (often branded under
Because TDK no longer actively hosts documentation for this legacy model, finding the official PDF requires targeted search strategies:
Response time is set too low, or the smallest step size programmed is too large for the load fluctuations.
High harmonic distortion caused by non-linear loads (VFDs, rectifiers) in the facility.
