GPS Time Sync System - T-PAN-300



Time synchronization creates a platform for an entire system comprising wide range of products to operate in synchronous with time. The demand for improving the effectiveness of any system in place is met with time synchronization system deployed in the field.

Troubleshooting is simplified by the application of time synchronization in the event of fault analysis. SERTEL manufactures GPS based Time Synchronization System which generates precise time stamp signals that synchronizes various network of electrical, computer, communications devices such as DCS, PLCs, LANs, Computer Buses etc.

Most modern protection relays and Intelligent Electronic Devices (IED) come with ports to accept the time synchronization signal.

Equipped with high precision and stable OCXO/TCXO, T-PAN-300 is capable of performing during temporary signal loss thus showing its accuracy and reliability.

The time stamp in the signal could be transmitted over long distance maintaining the synchronization of the whole network.





The signal from the satellite is collected by GPS antenna and transmitted to the GPS Receiver

SERTEL GPS Receiver generates time base pulses as that in the UTC or the atomic clock in the GPS satellite from the signal received.

Pulses can be generated for every second, minute or hour. Serial data packets comprising date and time information along with the pulses forms the time stamp and are made available in a variety of protocol format such as RS232, NTP/SNTP, IRIGB and many other to interface with wide range of devices.

LCD displays in the front panel shows the frequency, date, time and geographical location. These can be viewed with the help of keypad upfront. The status of the GPS receiver is shown by LED indications and alerts during failure through alarm provision.

Highly precise and stable OCXO/TCXO compensates for any interferences or loss of signal from the satellite thus making the operation of the receiver reliable. Redundant Master Clocks are provided for continuous functioning of the system.

Integrated inside one unit are the Redundant Comparators which receive input from the GPS Receiver and generates numerous output formats embedding time signals into them.

External time signal input provision as a source of time signal is provided.

Signal Conditioner units are provided to multiply the time signal in various protocols such as RS232, Pulse, PFC IRIGB, TCP/IP and many others to give that many number of provision for connecting other devices for time synchronization.

Redundancy in Power Supply is provided through redundant Diode Oring unit to maintain the exact voltage supply to all the units.
