Product Description

The series current transformer CT can be applied to test, control, display and record the running of the equipment against the damage in the AC circuit with the running of the electrical equipment, and to protect the equipment against the damage in the AC circuit with the rated voltage below 600V and the frequency of 50/60Hz. The products can be also applied to from a complete set of mine transformer.

Digital Servo Voltage Stabilizer Control Card, Digital Servo Voltage Control Module is equipped with an advanced Microcontroller Technology with self-controllable Design. It requires minimum external wiring for fast production of Servo Voltage Stabilizers.

The Main Features:
Display Module: To display the input and output voltages simultaneously.
Protection: The output voltage is disconnected, incase the feedback to the control card is disconnected or loose connected.

Programming: The Stabilizer Control Card can be programmed for the below parameters:

Low voltage cut off set Display shows-Lo

High voltage cut off set Display shows-Hi

Time delay relay set (TDR) Display shows-tdr

Hysteresis Display shows-HYS

Low Voltage cut off:
This value can be changed from 160V to 210V. Whenever there is any fluctuation present in the power supply to the extent that output voltage has turned out to be below this set voltage range then relay switches OFF.

High Voltage cut off:
This value can be changed from 220V to 254V. Whenever there is any fluctuation present in the power supply to the extent that output voltage has turned out to be above this set voltage range then relay switches OFF.

Time Delay Relay:
This value can be programmed from 15 sec to 180 sec. Whenever the output voltage goes beyond the low and high voltage range, the relay switches off. When the output voltage has reached in this range and now this much time (which has been programmed in TDR) is introduced and after this the relay turns ON.

The Temperature time constant of heater assembly is almost same as that of transformer winding and hence response to the change of transformer winding temperature by heater and in turn instrument is fast.
