Product Description
Programmable High-Current Generator is specially designed and manufactured for current load tests and temperature rise tests in electrical equipment testing, such as various switches, current transformers, and other electrical devices, for power departments and industrial/mining enterprises.
This series of products adopts split/integrated structure depending on product volume and weight, featuring stepless adjustment of output current, balanced current rise, wide load variation range, reliable operation, simple operation, and safety. It is an ideal equipment for current rise or temperature rise tests in industrial and mining enterprises.
Working Principle
After connecting the working power supply, this series of products adjusts the output voltage of the voltage regulator to obtain the required high current for testing.

Operating Environment
1. Working power supply: 220V/380V ±10% 50HZ
2. Ambient temperature: —10℃—40℃
3. The product should be placed in an environment free from gases, vapors, chemical deposits, dust, dirt, or other explosive media that could seriously affect transformer insulation.
Programmable High-Current Generator Usage Methods and Precautions
1. Connect the working circuit according to the electrical schematic diagram. The transformer casing and operation console must be properly grounded.
2. Connect the power supply, and the green indicator light on the operation console will illuminate. Press the start button, and the red indicator light will illuminate, at which point the current generator is ready for current rise.
3. Rotate the voltage regulator evenly clockwise, and observe the output current indicator on the operation console until the desired high current is reached. To ensure testing accuracy, a standard ammeter can be connected in series at the instrument terminals.
4. During the test, if any abnormal condition is found, immediately cut off the power supply, investigate the cause, and then proceed with the test.
5. After the test, the voltage regulator must be returned to zero, press the stop button to cut off the power supply, and disconnect the working power before removing the test wiring to ensure safety.
Complete Product Configuration
1. Operation console: 1 unit
