The RDJB-1600M Microcomputer Relay Protection Tester is a compact and high-accuracy testing device developed with advanced microelectronic technology. It combines the functions of large relay testers with the portability and easy operation of small testers.
With reliable performance, flexible operation, and high cost-effectiveness, the RDJB-1600M is an ideal tool for relay protection engineers to test and maintain power system protection devices.
Product Features
1. Supports flexible voltage‑current combinations. It outputs six‑phase voltage and six‑phase current for multiple modes such as 12‑phase output. It works with traditional tests and supports three‑phase transformer differential tests.
2. Supports standalone and PC‑controlled operation. Run the device locally or control it via external laptops or desktops for easy, efficient and stable operation.
3. Uses new high‑fidelity linear power amplifiers instead of switching amplifiers. It avoids high‑and‑mid frequency test interference and keeps accurate, smooth waveforms across full‑range current output.
4. High‑performance DSP‑controlled mainframe. It delivers high‑precision, low‑distortion output waveforms. Compact, lightweight and fully‑featured, it works right after power‑on for easy field testing.
5. Feature‑rich software. It handles complex automated verification, protection setting scanning, fault playback, real‑time data saving, vector display and online report printing. Six‑phase current simplifies three‑phase differential protection tests.
6. Built‑in independent adjustable DC output for 110 V and 220 V.
7. Comes with USB port for communication with computers and other external devices.
8. Complete self‑protection design. It has optimised heat dissipation, power soft‑start, fault self‑diagnosis and output latching for reliable hardware protection.
