The 8-Way AC to DC Power Supply Units can provide a 50W dc supply or a 100W dc supply depending upon whether one or two switch mode modules are incorporated in the power supply unit. Similarly, the 16-Way AC to DC Power Supply Units can provide a 50W, 100W, 150W and 200W dc supplies depending upon whether one, two, three or four switch mode modules are incorporated in the power supply unit. To calculate the power requirement: (1) Enter the number of devices of each type used in the system in column B. (2) Multiply by the unit power shown in column C. (3) Enter the result in column D. (4) Add up column D to calculate the total power required.Maximum power supply configuration allowed without provision for additional ventilation is 100w for 8 way cabinet and 200w for 16 way cabinet.

VENTILATION 

The System 57 Control System provides the facility for a large number of channels in a very small space. In heavily populated racks, especially those with many catalytic input control cards or relays configured for normally energised operation, it is possible for the heat dissipation to cause a significant rise in temperature both within the rack and in an area close to the rack. As such, careful consideration must be given to thermal planning. To achieve most from the convection cooling, always ensure that the air can flow freely through the rack and power supply. Do not obstruct the air vent holes in the top and bottom of the rack and if possible space the control cards evenly within the rack. It is recommended that during commissioning the operating temperature of the rack is checked to ensure that the maximum operating temperature of 55°C is not exceeded. In some cases the addition of forced air ventilation may be required.

PRELIMINARIES

 Ensure that each control card is compatible with the proposed sensor/ transmitter to be connected to that control card. Ensure that where an AC to DC Power Supply Unit is to be used, this is compatible with the local mains ac supply voltage and that the PSU power rating is adequate for its individual system load. Note: The model 05701-A-0405 and 05701-A-0406 AC to DC Power Supply Units operate, without the requirement of input voltage adjustments, from an 85V to 264V, 47Hz to 440Hz ac supply inputs.
