Material and components of a high grade shall be employed. The provided hardware equipment shall be new and it shall belong to a series production. No refurbished parts are allowed to be used in the system.
2.2.2 Working Environment
Full attention must be paid to the effects of the wide outdoor temperature variations. The antenna-pedestal subsystem, when installed inside a radome, shall operate in the temperature range from -40°C to +55°C and in relative humidity range from 0% to 95%, non-condensing. The proposed radome shall be dust- and waterproof, withstand wind speeds up to 65 m/s, and its operating temperature range shall be from -50°C to +70°C. The radome shall be equipped with a suitable temperature and humidity control for the prevailing conditions of the installation site.
The subsystems in the radar equipment cabinet shall operate in the temperature range from +10°C to +40 °C and in relative humidity range from 0% to 95%, non-condensing.
2.3 Power supplies.
2.3.1 Mains supplies.
The mains power supply shall be three-phase 230/400 V (+/- 10%), 50-60 Hz + 5 %. A 5-conductor system is used. The signal ground shall be separated from the protective ground. The AC neutral and the protective ground shall be kept separated in the equipment.
All power supplies shall have adequate internal protection against supply transients. The bidder shall provide a voltage stabilizer to supply all voltage-sensitive parts of the system.
2.3.2 Power Consumption
The maximum power consumption of the radar system shall not be more than 3.8 kW, including the antenna and the radar cabinet subsystems. The antenna-pedestal subsystem's maximum power consumption shall not exceed 1100W, and the radar cabinet's maximum power consumption shall not exceed 2700W.
2.3.3 Uninterruptible Power Supply (UPS)
The radar system shall be provided with an UPS system. The proposed UPS system shall support full operation of the radar for a minimum of 30 minutes. A back-up safety system shall be included to keep the radar safety system operational for a minimum of 24 hours even if the UPS battery runs out of power.
2.4 Automatic System Start After Complete Power Failure.
Automatic start-up capability after power recovery is required. The automatic startup must not require any manual operation of the radar.
The bidder shall provide the time from power attainment on to all aspects of the subsystem becoming operational. At system power-up start all control signals shall be in predefined states.
It must be possible to reset the radar equipment remotely be means of a TCP/IP connection. In the event of a missing TCP/IP connection, it must be possible to reset the radar equipment remotely by means of a GSM connection.
