Station Processor Unit - SPU
Depending upon specific requirements, two types of SPU are available:
Without local display
This type of SPU is mainly used for Self-Standing Stations type B and C, installed in remote locations of difficult access and/or where there is no power line available, to minimize the power consumption.
For maintenance purposes it is always possible to connect a service notebook to perform periodic checks or firmware upgrading.
With integrated touch-screen display This type of SPU is used for Self-Standing Stations type B and C, whenever the power consumption is not an issue and where an easier and faster access is preferred.
This SPU is based on a 6.5" industrial grade integrated processor and touch-screen terminal.
Power supply / Battery charger, featuring:
- Charging 12 V AGM batteries with high rate current
- Charging from AC and solar PV panel
- Maximum power point tracking (MPPT)
- Power output with battery protection
- Actual status display with backlight
- SDI-12 and RS-232 communication interfaces
- Operating currents, voltages and coulomb counting measurements
- Overload, overvoltage and reverse polarity resistant with notifications
Battery, AGM technology [Absorbed Glass Mat]
AGM Batteries are lighter than the flooded lead-acid type, extremely resistant to vibration, totally sealed, non-spillable and maintenance-free.
Solar Panel BlueSolar Monocrystalline, featuring:
- Low voltage-temperature coefficient enhances high-temperature operation.
- Exceptional low-light performance and sensitivity to light across the entire solar spectrum.
- 25-Year limited warranty on power output and performance.
- 5-Year limited warranty on materials and workmanship.
- Sealed, waterproof, multi-functional junction box gives high level of safety.
- High performance bypass diodes minimize the power drop caused by shade.
- Advanced EVA (Ethylene Vinyl Acetate) encapsulation system with triple-layer back sheet meets the most stringent safety requirements for high-voltage operation.
- A sturdy, anodized aluminium frame allows modules to be easily mounted.
- Highest quality tempered glass provides enhanced stiffness and impact resistance.
Outdoor housing
It consists of a suitable cabinet for outdoor operation, passivated Aluminum, painted with epoxy-polyester powder-coated metal finish or marine grade white, to be properly fixed to the Stand. Ingress Protection, IP68. An ABLOY lock is provided with 2 keys for cabinet security.
Stand
A stand is used for the installation of the AGDM Gamma Dose Rate Monitor, and its sub-systems including solar panel, in-built rechargeable batteries and Data Modem.
