XL-750 GPS Time Source for Power Industry _详细资料

产品信息 产品名称： XL-750 GPS Time Source for Power Industry 规　　格：产品备注：产品类别： GPS定位及时钟基准系统 Symmetricom’s XL-750 GPS Time Source has been developed to address key power industry timing requirements. Whether it’s the monitor, control or analysis of the power system, the XL-750 is the cost-effective GPS time synchronization solution. The XL-750 directly meets the recent recommendations from NERC (North American Electric Reliability Council) for event timing at power substations. Specifically, it fully satisfies NERC’s Recommendation # 12 concerning GPS time-synchronized recording devices. Using GPS satellites, the XL-750 generates extremely accurate output pulsestime codes in multiple formatsoffers superb timing accuracy (100nanoseconds to UTC). The XL-750 synchronizes a wide variety of microprocessor-based power system equipment including: SCADA systems, remote terminal units (RTUs), protection relays, sequence of event recorders, digital fault recorders, power/tariff metersother intelligent electronic devices (IEDs). Field programmable using a Windows-based configuration program, the XL-750 allows the user to define time code formats, output pulses ratesdurations, device status,a wide variety of operational parameters. Each output can feed directly to different areas through electrically isolated outputs which insures reliable operation in a harsh substation environment. The XL-750 generates a wide range of timing signals via four output ports. A fixed output provides an IRIG B amplitude modulated (AM) time code signal. Three independently configurable digital ports can provide pulse rates or unmodulated (DC level shift) time code. The XL-750 pulse output is easily configured to provide common power industry pulse rates including a 1 pulse-per-second (PPS), 1 pulse-per-minute (PPM),1 pulse-per-hour (PPH). Signal levels are also selectable at time of order from TTL (standard) to optional RS422, fiber optic or high voltage MOSFET switch. A RS232 serial port is provided for configurationsynchronous time string broadcasts. A dual channel event time tagging option is available for precise time tagging of external event pulses. Also available is network time server option to synchronize computers with the Network Time Protocol (NTP).
