Product introduction
RDJB-702L 3-Phase Relay Protection Tester
 

  Product Introduction

  The RDJB-702L relay protection tester is a new miniaturized microcomputer relay based on the technical conditions (discussion draft) of the microcomputer-based relay protection test equipment issued by the electric power department, and a wide hearing from the user's opinions, the advantages and disadvantages of the same kind of products at home, and the full use of modern advanced microelectronic technology and devices. Protection tester. The relay protection tester is run independently by a single machine. It can also be connected with the advanced structure operated by notebook computers. The host has a new generation of high speed digital signal processor, true 16 bit DAC module, a new modular high fidelity high-power amplifier, a large screen LCD and a flexible and convenient mouse controller. The stand-alone operation has strong functions. It can carry out most tests. The operation of connecting computers has a more powerful operation function. Small volume and high precision. It not only has the superior performance and advanced function of the large test instrument, but also has the advantages of small and flexible test instrument, easy operation and high reliability, and the performance price ratio is high. It is a good tool for the protection workers.

  Features:

  1. The relay protection tester uses a high speed and high performance digital control processor as a control microcomputer. On the software, the dual precision algorithm is used to generate arbitrary high precision waveforms of each phase.

  2. High speed D/A converter is adopted to ensure the accuracy and linearity of current and voltage in the whole range.

  3. Power amplifier circuit adopts high power high fidelity modular power device as power output level, combined with careful and reasonable design of heat dissipation structure, with sufficient power redundancy and thermal capacity.

  4. Switch input circuit can be compatible with the air gap and 0 to 250V potential contacts.

  5. The instrument uses 320 * 240 dot matrix high resolution blue backlight LCD display as monitor.

  6. The device is equipped with an adjustable DC power output on the chassis floor, which is divided into 110V and 220V two files. It can be used as auxiliary power for field test.
