Explanation/Annotation:Electronic. For the protection incorporated ôðåîíîìàñëîñòîéêèõ electric motors of compressors from overheating.
Detailed model description:Can be used for operation in íåâçðûâîîïàñíûõ premises and
Outdoor installations, as well as in premises with explosive zones of classes of Â-1à of Â-1á Â-1ã Â-11à.
Is used complete with temperature sensors - of type thermoresistors
ÑÒ-14-1 "A" or ÑÒ-14-1 "of b", built into electric motor windings.
The operation threshold of ÒÐÝ 201 is determined by the resistance increase of temperature sensor up to 2200 ohms, that permits its use in any other automatic regulation systems.
On individual order may be supplied with the other operation threshold,
Selectable in the range between 500 ohms up to 10 lumps, that make it possible of its use with the other RTD, pressure, level and ton. P. The electrical load on being heated of one or more sensors up to temperature 105 or 130°Ñ (depending on modification of temperature sensor is disconnected). There is a possibility of self-blocking.
Basic error, °Ñ -, - 1.
Power consumed, ·À - 4.
Switched the ac power:
From 0, 1 up to 1, 5À on tension 12-380Â and
More than 1, 5 up to 2, 5À on tension 12-250Â and inductive loading
Cosª0, 6; in this case in case of inclusion the current increasing up to 6À is allowed and
Elapsing time of it not more than 0, 1Ñ;
More than 2, 5 up to 6À on tension 12-250Â and
More than 2, 5 up to 10À on tension 12-240Â and resistive load; in this case
Time of continuous current flow up to 10À through contacts not more than 15ñ.
