Applications
- Power supply decoupling: Decouples two SITOP power supplies with max. 20 A output current each.
Key Features
- Redundancy function: Suitable for decoupling two SITOP power supplies with max. 20 A output current each.
- Input and output: Input voltage at DC: 24 … 28.8 V; output voltage at DC rated value: 24 V; rated output current: 40 A.
- Status indication: Green LED indicates both input voltages are above the switching threshold; red LED indicates at least one is below it.
- Relay signal: Isolated relay contact with changeover contacts, rated 8 A/240 V AC, 24 V DC; switching threshold setting range: 20 … 25 V.
- Connections and mounting: Screw terminals; input, output and ground each use 1 screw terminal for 0.33 … 10 mm2 conductors. Snaps onto DIN rail EN 60715 35×7.5/15.
- Protection and coating: IP20 protection, Class III operating resource protection, and conformal coating, Class A according to IPC-CC-830A.
