663B microcomputer relay protection tester

Product Overview:

◆663B microcomputer relay protection testerMeet all on-site testing requirements. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential protection and backup automatic switching devices, making testing more convenient and efficient.

The APWR434 (B) model has a standard four phase voltage and three-phase current output simultaneously, with a voltage of 125V/phase and a current of 40A/phase. The three-phase current can reach up to 120A in parallel. Among them, APWR434B is a built-in industrial control model, while APWR434 is a non industrial control model that can only be operated with an external laptop. The usage method and technical parameters of these two models are the same.

The APWR663 (B) model has a standard six phase current and six phase voltage output simultaneously, with a current of 30A/phase and a voltage of 125V/phase. Six phase current parallel connection can reach 180A. Among them, APWR663B is a built-in industrial control model, while APWR663 is a non industrial control model that can only be operated with an external laptop. The usage method and technical parameters of these two models are the same.

All technical indicators meet the standards of DL/T624-1997 "Technical Conditions for Microcomputer based Test Devices for Relay Protection" issued by the Ministry of Electric Power.

Single machine independent operation, built-in high-performance industrial computer, with a main frequency of 300-600MHz and 128M memory, running Windows XP operating system.

The domestic industry is the first to adopt imported brushed stainless steel panels, stainless steel keyboards, and touch sensitive mice, overcoming the disadvantages of inflexible and easily damaged operation of trackball mice. An 8.4-inch TFT true color display screen with a resolution of 800 × 600 is also selected, making the overall operation of the single machine convenient and durable.
