TD2418B多功能電力轉(zhuǎn)換器的產(chǎn)品介紹: The TD2418B is a micro-process based transducer with a 16 bits CPU (Center process unit) and equipped with full-digitized measuring, calibrating and output functions. TD2418B not only can take the place of several static con-verters and measuring instruments (V, A, W, PF, VAR, WH, VARH, Hz) by single unit, but also have some special function such as Maximum measuring, Minimum measuring and comparator output. In communication, we use the most convenient and the easiest RS232 or RS485 as our standard output port, besides, we adopt Modbus Protocol, one of the most popular protocol in the world, as our standard protocol. TD2418B多功能電力轉(zhuǎn)換器特性 ? Precision True-RMS measurement even for distorted waves ? High immunity to external noise ? RS485 standard communication interface output ? Auto calibration from computer ? Maximum and Minimum function ? Power supply is AC 90V～260V, 50/60Hz 詳細(xì)規(guī)格 Accuracy: (at 23±5℃ sine wave)Voltage±0.1% of reading±0.15% of range Current±0.1% of reading±0.15% of range Watt±0.2% of reading±0.3% of range Var±0.2% of reading±0.3% of range Power factor±0.5% of reading PF polarity"＋" lagging, "－" leading Watt hour±0.25% of reading±1 Count Var hour±0.4% of reading±1 Count Hz±0.2% of reading Max. input over capabilityAmp. 10A continuous 50A for 5 sec.
