GPS NTP Time Servers

GPS NTP Time Server

GPS NTP Time Server(GPS Time Synchronized Clock)

Product descriptions:

The SY series of GPS Standard Time Synchoronous Clock that we manufactured are specifically for power system, automatizatio system, communicate system and traffic system that need high-precise time requirer.Our system is based on GPS, and the precision of time is 1µs.The facility is secondary developed with the GPS receiver that made by the special factory of United States. It can track 12 GPS satellites at the same time, and selects the best satellite automaticly for locating and timing.It outputs 1PPS, 1PPM, 1PPH time pulse and UTC time ,and the synchronous precision is 1µs, and it can measure the industrial frequency, and outputs date, time, cycle clock, cycle, clock difference, safe running days, and so on through RS232 serial with two formats. It is selected to used by automatization facilities that need standard time in electric power system.

Technical parameter:

1. Receiving frequency:1575.42MHZ, it can track 8-12 GPS satellites at the same time.

2. Antenna radio sentivity:-166dbw, with 30 metres wire. If the wire is not long enough, customer can prolong it by himself by selection of coaxial-cable that attenuation of

1.56GHZ is not more than 0.7db per metre, the attenuation of prolonged cable is not more than

5db.

3. Capture time: from 20 seconds to 2 minutes

(Annotate: the outputs of synchronous clock are all isolated by photoelectricity coupling and output 60ns)

4.1PPS output:

Timing varacity: 1µs Voltage: TTL voltage Polarity: positive pulse Pulse width: about 100ms Impedence: 50 Ώ Channel number: 1

Fore edge: <20ns

5.1PPM: output:

Timing varacity:: 1µs Voltage: TTL

Polarity: positive pulse Pulse width: about 100ms

Impedence: 50 Ώ Fore edge: <20ns

6.1PPH output:

Timing varacity:: 1µs Voltage: TTL

Polarity: positive pulse Pulse width: about 100ms

Impedence: 50 Ώ Fore edge: <20ns

7.Cycle precision: ±0.001

8.Industry frequency clock: the clock that is promoted by industry electricity is synchronous with standard clock when power is on.

9.Clock difference: that is standard clock minus industry frequency clock,synchronous time difference is zero,precision is 20 ms.

10.Longitude, latitude: where the electric power synchronous clock locates.

11.Display: 14 bits LCD display that includes cycle,date,time,longitude,latitude,industry frequency clock,clock difference (standard clock minus industry frequency clock).

12.RS232: output time code (year, month, day, hour, minute, second), industry frequency clock time(hour, minute, second), clock difference,cycle.

13.RS232: output “ST” format time code (selected by switching circuitry)

14.Power: AC110V to 240V or DC12V to 48V, 10%, 15W.

15.Size: standard industry 19 inch 2U box.1U and 3U can also be provided.

16.  OEM is accepted.

Product features and advantages:

1.SY GPS NTP time server supports GPS or BD satellite systems.
