The class represents IEEE Std 421.5-2005 type DC2A model. This model represents represent field-controlled dc commutator exciters with continuously acting voltage regulators having supplies obtained from the generator or auxiliary bus. It differs from the Type DC1A model only in the voltage regulator output limits, which are now proportional to terminal voltage . It is representative of solid-state replacements for various forms of older mechanical and rotating amplifier regulating equipment connected to dc commutator exciters. Reference: IEEE Standard 421.5-2005 Section 5.2.

Documentation of parent class DynamicsFunctionBlock:
Abstract parent class for all Dynamics function blocks.
- enabled
Function block used indicator. true = use of function block is enabled false = use of function block is disabled. Default: False
Documentation of parent class IdentifiedObject:
This is a root class to provide common identification for all classes needing identification and naming attributes.
- DiagramObjects
The domain object to which this diagram object is associated. Default: “list”
- mRID
Master resource identifier issued by a model authority. The mRID is globally unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended. For CIMXML data files in RDF syntax conforming to IEC 61970-552 Edition 1, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements. Default: ‘’
- name
The name is any free human readable and possibly non unique text naming the object. Default: ‘’
- description
The description is a free human readable text describing or naming the object. It may be non unique and may not correlate to a naming hierarchy. Default: ‘’
- energyIdentCodeEic
The attribute is used for an exchange of the EIC code (Energy identification Code). The length of the string is 16 characters as defined by the EIC code. References: Default: ‘’
- shortName
The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum. Default: ‘’
