Eaton 15-871-6 AF5000+ Power Supply Board (P‑CTR 158716)
The Eaton 15‑871‑6, cross‑referenced as P‑CTR 158716, is a critical internal component for AF5000+ series variable frequency drives. This power supply board generates all necessary low‑voltage DC rails required by the drive’s main control board, interface modules, and IGBT gate drivers. It is designed as a direct replacement to restore functionality in case of power supply failure, ensuring minimal downtime.
Key Features
Input: derived from DC bus (typical range 300‑800 VDC) or auxiliary AC supply
Output voltages: +5 V, ±15 V, +24 V (isolated) for control electronics
Isolated outputs for gate drive circuits (floating supplies)
Overcurrent and short‑circuit protection on all outputs
LED indicators for status monitoring (power good)
Pre‑drilled mounting holes matching AF5000+ chassis
High‑quality electrolytic capacitors for long life
Technical Specifications
Input voltage range (DC bus): 200‑800 VDC (depending on drive rating)
Input voltage range (auxiliary): 110‑230 VAC, 50/60 Hz (optional)
Output capacities: 5 V @ 2 A, ±15 V @ 1 A, 24 V @ 1 A
Isolation voltage: 2500 VAC between primary and secondary
Operating temperature: -10 °C to +50 °C (inside drive enclosure)
Cooling: Natural convection (requires airflow in drive)
Dimensions: 180 x 140 x 30 mm
Compatibility
This power supply board is specifically engineered for AF5000+ drives of various power ratings. It is recommended to verify drive model and serial number before ordering. The board is often located near the control board and can be replaced by a qualified technician following standard safety procedures (discharge DC bus capacitors).
Applications
Replacement for faulty power supply in AF5000+ drives
Spare part for maintenance stock
Drive refurbishment and upgrade projects
Repair of industrial automation systems using AF5000+
Quality and Reliability
Eaton manufactures the 15‑871‑6 board to the same specifications as the original, using high‑grade components and rigorous testing. Each board undergoes functional testing to ensure correct output voltages and protection features. Using genuine Eaton parts guarantees compatibility and safety compliance with CE and UL standards for the drive system.
For maintenance teams and service centers, having the 15‑871‑6 power supply board on hand minimizes repair time and keeps critical processes running. Always follow lockout/tagout procedures when handling drive internals.
