Detailed Description

Circuit Breakers are one of the critical “safety-valves” of electrical systems and basic maintenance procedures are essential to maintain maximum reliability. This instrument is designed for testing DC circuit breakers at rated current of 1A-500A. It is suitable for on-site test of substations. Features The instrument can be used separately or linked to PC. 320*240 LCD screen, thermal printer, interactive keyboard operation, and intelligent operation system. Power electronics controlling technique has been adopted to output high current, which is high speed, high precision and continuous adjustability. Current range can be automatically switched by multiple high precision sensors.14 digit AD acquisition chip of high capacity. Automatic data storage. Be capable of saving 200 testing results, which will not lose in power failure. Optional for ampere-second characteristic test or through current characteristic test. When linking to PC, it is available to do following operations, such as controlling the instrument, data importing, data saving, data report and data graph generation. Protection functions for overheat, over-current and over voltage. Anti-interference capacity and good EMC(electromagnetic compatibility). Specifications Power supply: AC220V±10%, 50Hz±0.5Hz Testing current range: 0-500A (can be extended to 1000A) Testing current ripple coefficient: <2% Stability of output current: ≤0.5% Ampere-second characteristic test: Time:0-9.9s; Time resolution(min.): 0.1ms Through current characteristic test: time:0-9999s; Time resolution(min.): 0.1s Environmental temperature: -20--50℃. Size: 560*410*350mm Weight: 31kg.
