DIN-rail dual-input decoupling diode module for redundant 10 - 60 V DC power supplies or to separate sources and loads; up to 25 A output, 2 x 12.5 A in 1+1 redundancy.
Price and availability on request
Key features
- Dual input diode with 2 inputs and one output
- Builds redundant (1+1) systems by decoupling power supplies from each other and from the load
- Separates sensitive loads from the power bus, builds buffered branches and blocks reverse power
- Input / output: 10 - 60 V DC; output current 0 - 25 A max.
- Single input mode: both positive input terminals can be linked
- Convection cooling, no fan required
- DIN-rail mountable, extremely small size
- 3 year warranty
