What is the Wago 787-1685?

Features:

Redundancy module with low-loss MOFSET decouples two power supplies.

For redundant and fail-safe power supply

Continuous output current: 40 ADC, in any ratio of both inputs (e.g., 20 A / 20 A or 0 A / 40 A)

Suitable for power supplies with PowerBoost and TopBoost

Same profile as CLASSIC Power Supplies

Electrically isolated output voltage (SELV/PELV) per EN 61140/UL 60950-1
