Satellite ground stations handle satellite signal transmission/reception, data transmission, and command delivery, requiring extremely high power continuity. If mains power fails, antenna control systems, modems, and data servers must switch to backup power within milliseconds; otherwise, satellite links may be interrupted, data lost, or even satellites go out of control. Ground stations are often in remote areas with weak grids, and equipment remains on float standby for long periods, demanding high battery stability and lifespan.
VELA POWER VRLA (Valve-Regulated Lead-Acid) batteries are designed for high-reliability backup power, offering millisecond response, long float life, and a maintenance-free sealed structure, ensuring uninterrupted satellite signal transmission and reception around the clock.
Q1: How does VELA POWER VRLA ensure seamless takeover when mains power fails?
A1: With low internal resistance and high-conductivity plates, it delivers excellent instantaneous high-current discharge. When mains fails, it takes over the load within milliseconds, providing stable power for antenna control, modems, and data transmission, ensuring no satellite link interruption or data loss.
Q2: How does it extend service life under long-term float standby?
A2: The battery automatically reabsorbs gases generated during charging and converts them back into electrolyte, recycling internally. This results in almost no electrolyte loss and no need for regular water topping-up. Combined with corrosion-resistant grid alloys, it maintains stable performance under long-term float charging, greatly reducing replacement frequency and O&M costs.
Q3: What are the maintenance-free advantages for remote, inconvenient locations?
A3: Fully sealed construction requires no electrolyte level checks or distilled water addition, achieving true maintenance-free operation. O&M personnel can monitor voltage and internal resistance remotely to assess battery status, reducing on-site inspections—ideal for unattended ground stations in remote areas.
In summary,with millisecond response, long float life, and maintenance-free sealed construction, VELA POWER VRLA batteries precisely meet the high-reliability backup power requirements of satellite ground stations. They keep satellite signal transmission and reception uninterrupted and space-ground communication links open at all times—a trusted “ground power source” for satellite ground stations.
