Applications
- Redundant power supply: The PS407 is designed for redundant use.
- Backplane bus power: The power supply provides 5 V DC and 24 V DC for the backplane bus.
Key Features
- Wide-range input: Rated input values are 120 V AC, 230 V AC, 120 V DC, and 230 V DC.
- Backplane bus output: Output is DC: 5 V DC at up to 10 A for the backplane bus, with no base load required, and 24 V DC at up to 1 A, idling-proof.
- Input frequency: Rated line frequency is 50 Hz or 60 Hz; the permissible range is 47 Hz to 63 Hz.
- Mains buffering: Stored energy time during mains or voltage failure is 20 ms; mains buffering follows the NAMUR recommendation.
- Protection and isolation: The power supply has short-circuit protection, primary/secondary potential separation, overvoltage category II, and equipment protection class I with protective conductor.
- Installation and backup: The hardware configuration requires 2 slots. An optional backup battery is 1x lithium AA, 3.6 V / 2.2 Ah.
