从China供应商批发进口Jzxc-480 Type Rectifier Relay — FOB条款

Product Introduction The JZXC-480 rectifier relay is an important component in the chain equipment and the main equipment to ensure the safe operation of the system. The signal relay can control the switching of the turnout, lock and unlock the route, and control the opening and closing of the signal machine. Its reliability, availability, maintainability and the entire sauna line are the keys to the safety of railway transportation and operational services. The automatic control systems in various fields all use relays. Product Usage The JZXC-480 rectifier relay is used as an AC rail and AC accident relay in the signal circuit. test method Requirements for testing measuring tools, meters, and power supply (1) The accuracy of the measuring tool for measuring the shape and installation dimensions should not be less than 0.05mm; the accuracy of the feeler gauge should not be less than level 2; the measurement error of the force measurement should not be greater than 2%. (2) The accuracy of the DC voltmeter and ammeter used for testing should not be less than 0.5, and the accuracy of the AC (50Hz) voltmeter and ammeter should not be less than 1 (3) The power supply voltage should remain stable, and its fluctuation range should not exceed 5%. The DC power supply should be a DC generator, battery or AC full-wave rectifier power supply (except for special regulations, the ripple factor should not be greater than 5%). The waveform of the AC power supply should be a sine wave with a frequency of 50 Hz. Features The relay is composed of a DC infinite relay and a full-wave rectifier circuit. Applicable environment a) Ambient temperature: -40â??~+60â??; b) Relative humidity: not more than 90% (temperature +25â??); c) Air pressure: not less than 70kPa (equivalent to below 3000m above sea level); d) Vibration: the vibration frequency is not more than 15Hz, and the amplitude is not more than 0.45mm; e) Working position: horizontal; f) There should be no harmful gas causing explosion hazard around, and good dust-proof measures should be taken.
