Time and Frequency Solutions
Every protection relay, trading log, radar track and network switch depends on one quiet assumption: that the clock is right. Sertel's Time and Frequency range turns satellite time into a trusted reference for your entire facility, delivered over NTP, PTP IEEE 1588 and IRIG-B, and made visible on synchronised displays your operators can read at a glance.
GPS / GNSS NTP Time Server
GPS / GNSS NTP time servers take UTC from GPS, GLONASS, Galileo, BeiDou and IRNSS satellites and serve it at Stratum 1 to every PC, PLC, RTU and IED on your network. The PreciseSync SMC-300 series comes in three builds: compact rack, fully redundant and DIN rail.
GPS / GNSS NTP Time Server
PreciseSync - SMC - 300
A 1U 19 inch rack Stratum 1 server with 14 ns timing accuracy under GNSS lock and a front-panel LCD. It drives slave clocks and digital displays directly, alongside NTP, IRIG-B and DCF77 outputs.

GPS / GNSS NTP Time Server
PreciseSync - SMC - 300 - R
Duplicated GPS receivers, master clocks, comparator units and power supplies on Eurocard PCB construction. Built for substations and control systems that must keep time through a component failure.
Know more
GPS / GNSS NTP Time Server
PreciseSync - SMC - 300 - D
A panel-mounted Stratum 1 server for control cabinets without rack space. It sends IRIG-B (AM) and NTP over Ethernet to SCADA, IEDs and protection relays from a single DIN rail unit.
Know moreGPS / GNSS PTP IEEE-1588 Systems
GPS / GNSS PTP IEEE-1588 Systems from Sertel lock to multiple satellite constellations and distribute sub-microsecond IEEE 1588v2 time to relays, IEDs, switches and controllers. Choose a compact rack server, a fully redundant build or a DIN rail unit for the panel.
GPS / GNSS PTP IEEE-1588 Systems
PreciseSync - GMC - 300
A compact 19 inch rack PTP time server with OCXO holdover and 15 ns timing accuracy under GNSS lock. One unit feeds PTP Ethernet, IRIG-B, 1PPS and any number of slave clocks.
Know more
GPS / GNSS PTP IEEE-1588 Systems
PreciseSync - GMC - 300 - R
Redundant GNSS receivers, master clocks, comparator and dual power supplies in a 2U or 3U Eurocard chassis. Built for substations and control rooms where time must never stop.
Know more
GPS / GNSS PTP IEEE-1588 Systems
PreciseSync - GMC - 300 - D
A panel-mounted PTP time server that fits inside control cabinets without rack space. Delivers IRIG-B (AM) and PTP Ethernet from a multi-constellation GNSS receiver with OCXO holdover.
Know moreDigital Display
Put one trusted time reference on every wall, panel and control desk in your facility. Sertel digital displays read time from your NTP server or IRIG-B master clock and show it in large LED characters that stay readable across plant floors, control rooms and corridors.
Digital Display
NTP Time Display 100mm (T-SL-300-100-6DN)
A six-digit wall clock that pulls time straight from your NTP server over the existing Ethernet network. The everyday choice for offices, control rooms and production halls that already run a time server.
Know more
Digital Display
NTP Date Display 100mm (T-SL-DD-300-100-6DN)
Shows the current date in large LED digits, synchronised to the same NTP source as your clocks. Pair it with a time display at shift boards, gate houses and reception areas so logs and records never disagree.
Know more
Digital Display
NTP Day Display 100mm (T-SL-300-100-3DN)
A compact three-character display that names the day of the week, driven by NTP. Useful on shop floors and in maintenance bays where weekly schedules and rotating shifts decide who works where.
Know more
Digital Display
NTP Alpha Numeric Display 100mm (T-SL-300-100-ADN)
A 28-character, multi-row LED board that combines time and date with live plant values such as frequency, MW output or ambient temperature. Reads data over Ethernet, OPC or 4-20 mA and supports scrolling and flashing messages.
Know more
Digital Display
NTP Time Display 150mm (T-SL-300-150-6DN)
Our largest standard time display, built for turbine halls, warehouses and assembly floors where staff read the clock from a distance. Accepts NTP, PTP, IRIG-B, RS-232, RS-485 or differential pulse input in a wall-mount housing.
Know more
Digital Display
NTP Time Display 14mm (T-SL-300-014-6DN)
A small-character NTP clock sized for panel fronts, server racks and operator consoles. It brings the same synchronised time to close-range viewing points where a wall display would be oversized.
Know more
Digital Display
IRIG - B Time Display 100mm (T-SL-300-100-6D)
A slave clock for sites that distribute time from a master clock rather than over the LAN. IRIG-B or differential pulse input on a multi-drop bus drives up to 300 displays within a 1 km radius, and one failed unit never stops the rest.
Know more
Digital Display
Frequency Display 100mm (T-FDU-300-100-5D)
A five-digit LED readout of supply frequency for substations, generating stations and switchyards. It gives operators an at-a-glance view of grid conditions alongside the station clock.
