ORDERING INFORMATION

> The ISTAT I300 model number comprises of 10 digits, the first 6designates the basic type of transducer whilst the next 3 are specificto the customers precise configuration. The last digit is for designsuffix.

Depending on the transducer, the following information is also required :

Input parametersVoltage, Current and power in secondary valuesTransformer ratios and voltage, current and power in primarly values

Scaling information : Output parametersHow is the analogue output configured, is it based on primary orsecondary values, and what do the maximum and minimum analogueoutputs scale to.

> 3B DC/DC CONVERTERThe DC/DC converter follows a different model numbering systemusing only 6 digits.

Note : the 3BG has only a single output, but this can be used to supplyupto 8 3BC 48V converters.

> 3EA RESISTOR BOXThe 3EA resistor box has 9 digits in the model number, the first 3 identify the type, the next 2 digits the number of resistors, the next 3 digits the resistor values and the last digit being the design suffix.

A special 3EA resistor box has been designed for use with the MICOM KVGC voltage regulation relay, this is called 3EA22A390A
