KDJB-40A microcomputer relay protection tester or Injection Kit protection relay tester for Three Phase Relay Protection Tester
KDJB-40A microcomputer relay protection tester adopts high speed and high performance digital control processor as control microcomputer, and the software uses double precision algorithm to generate arbitrary high precision waveform of each phase. Because of the integrated structure, each part is closely combined, the data transmission distance is short, and the structure is compact. It overcomes the problem of low number of output waveform points caused by long data communication line and narrow
frequency band in the measurement and control instrument directly controlled by laptop computer.
Product Paramenters
Ac current output
Output accuracy: 0.5 level
Phase current output (effective value) : 0 to 40A
Triple current output (effective value) : 0 to 120A
Allowable operating value of phase current for a long time (effective value) : 10A
The high speed D/A converter ensures the accuracy and linearity of current and voltage in the whole range.
Each phase current, voltage does not use the current, booster, and the use of direct output mode, so that the current, voltage source can directly output from DC to contain various frequency components of the waveform
Switching input circuit is compatible with null contact and 0 ~ 250V potential contact. In potential mode, 0 ~ 6V is combined, 11~ 250V is divided.
Manufacturing Technique
Standard 4-phase voltage and 3-phase current output: with 4-phase voltage and 3-phase current output, it is convenient to carry out various combinations of output for various types of protection tests.
Single machine easy to operate: single machine by convenient and flexible mouse through the large LCD screen for operation, all English display.
Large LCD screen: This machine adopts 320×240 dot matrix large screen high resolution graphic LCD screen, all operation process is set on the screen.
It has an independent special DC power output device with a 110V and 220V special adjustable DC power output.
