Output protection
The relay outputs may be protected externally against parasites generated by an inductive load with: - a varistor or an RC module, in alternating current - a free-wheel diode, in direct current The presence of an external thermal fuse, connected to the common power supply of the outputs, protects to the output connected devices. 1.4.7.4 Cabling of the CS 31 bus The CS 31 bus is a RS 485 serial interface and consists of a shielded twisted pair. This bus is a master slave bus and only accepts a single master. Use a AWG 24 (0.22 mm 2 ) to AWG 18 (0.18 mm 2 ) twisted pair. The maximum length is 500 m. The same cable type should be used for the whole system bus setup. Bus interruptions should be avoided, during cabinet cable connections for instance, otherwise it should be cabled to the same side of the terminal block Warning: STAR connection of the bus is not permitted! The central and remote units may be connected at any point of the bus: - bus 1 on bus 1 - bus 2 on bus 2 - shielding (preferably braided) on terminal 3 of terminal block 1 and earth connected at the master level (cable < 1 m) The bus should be terminated with a 120 ? 1/4 W resistance connected to the bus extremities. The twisted pair should be symmetrical
Product Overview
The Trusted? Power System is a high density flexible power supply designed to convert main line voltages of either 110 Vac or 240 Vac. Outputs are either 24 Vdc for Trusted product or 28 Vdc adjustable field power. The Trusted Power System consists of a 1U Power Shelf with mechanical support, containing up to three 750 W Power Packs. The Power Packs load share in configurations using one or more Power Shelves. Each Power Pack has an individual supply connection via a mechanically retained IEC 60320 type connector. Each Power Shelf can supply 2250 W of power or 1500 W with n+1 redundancy from a single source. Multiple units can be connected for further capacity or redundancy requirements. Diagnostic information of Power Pack status is provided via the Power Port, which connects to the rear of the Power Shelf. This device monitors input and output conditions and reports out of range faults and over-temperature/fan failure using relay contacts. The Power Port also allows connection of the optional rack mounted Power Controller for live configuration, of output voltage and current, monitoring up to 12 Power Packs in 4 Power Shelves.
Features: ? Redundant and N+1 configurations. ? Hot replaceable Power Packs. ? Current sharing. ? Current limiting. ? Power factor correction. ? Diagnostic contacts. ? Configurable output voltage. ? Input/output fail diagnostics per power pack.
