INSTALLATION
COOLING REQUIREMENTS
Heatsink temperature rating for standard stack assembly is calculated when naturally cooled. If mounted in enclosure or cabinet, adequate
ventilation and/or forced air-cooling should be fitted. Thermal trips are fitted on 75A to 100A rated controllers. This is in order to switch off the
thyristors in an over temperature situation, which is indicated by an LED. The trip resets when the temperature falls below 90° C.
LOAD CONSIDERATIONS
It is always advisable to indicate the type of load when ordering. For industrial reliability, based on long experience, the SAC range has
considerable current overload capacity on the power devices used. The rated currents are maximum continuous RMS values for use within the
temperature guidelines as shown in the table below.
Unusual heating loads such as Molybdenum, Platinum or Tungsten have a typical 10 to 1, hot to cold, resistance ratio and therefore, when cold,
draw larger currents than normal. Transformers and other inductive loads have surge starting currents and require the correct type of phase
angle firing circuit. These and similar types of surge loads should be indicated, so that appropriate slow start or larger rated units can be correctly
supplied for the specific needs.
Fusing
It is recommended that fast acting semiconductor type fuses (as supplied) be used for protection. See SRA Data sheet X10255 for further
information. Other external supplies should be fused accordingly.
CE Marking
This family carries a “CE” marking, In burst fire mode the controllers do not normally require a remote filter. For more information contact our
sales desk. A Declaration of Conformity available on request.
