The SPC 512 card is a compact power supply, standard Single Europa size measuring 100x160mm, inserted in a standard 3HE Rack together with the cards it supplies power to.

Thanks to the small size and to the industrial format, it is the ideal component to match to other Motherboards as YPB 01, SPB 04, SPB 08, etc to enable the composition of boards which afford any automation problems.

The SPC 512, to respect the security norms, provides for a low power supply input which can be alternate or continuous; there is also an auxiliary input coming from an external battery; in this case, SPC 512 works like an UPS (Uninterruptible Power Supply), assuring power to the load, with no discontinuity, even without external mains voltage.

Special filters on the inputs and outputs, the accuracy in the circuitry disposition, an efficient protection executed by TransZorb™, unfailing thermic protections, etc. make of SPC 512 a reliable and safe power supply which can be used in the strongest applications.

Three LEDs in the front side inform about the correct working of the power supply. One of them indicates the failure. It lights whenever each anomalous condition (over load, extra voltage, high temperature, etc.) cause an interruption of power supply on +5Vdc.

The SPC 512 produces two typical supplies which are necessary for the power supply of the ABACO® board.

The first is +5Vdc which can have maximum 5A and which supplies power to all the logics. The SPC 512 provides a /RESET signal, so that the boards start only once +5Vdc is within the correct values. The second power supply is +12Vdc with a maximum of 2,5A.

This power supply is generally used only by peripheral boards which mount output relays as CI/O 01, CI/O R16, etc. It is necessary to have two different power supplies to avoid noises, generated by the simultaneous commutation of all the output relays, on the same voltage that supplies the control logic, above all when the number of relays is very high.

For example, the SPC 512 supplies power at least twelve CI/O 01 giving a total of 192 Relays and still are available 2A on 5Vdc to supply further single power boards .

• - Single Europa size measuring 100x160x35 mm
• - Electrical connection by the strong connector DIN 41612 type F
