Product Description
OPzS490-2 Flooded Lead-Acid Battery (For Power System Substation DC Operating Power Supply)
I. Core Specifications
- Model: OPzS490-2
- Rated Voltage: 2V
- Rated Capacity: 490Ah (C10, 25℃)
- Battery Type: Tubular Plate Flooded Lead-Acid Battery (OPzS)
- Design Float Life: 20 years (at 25℃)
- Maintenance Interval: Low maintenance, electrolyte replenishment cycle ≥3 years
II. Key Advantages
-
Extreme Environmental Adaptability
Operating temperature range of -40~65℃, delivering stable performance even in harsh substation conditions.
-
Low Maintenance & High Safety
Acid-proof and explosion-proof design meets DIN40736 safety standards. The extended electrolyte replenishment cycle significantly reduces on-site maintenance work.
-
Superior Cycle & Deep Discharge Performance
Excellent cycle life (e.g., 3000 cycles at 50% DOD) with strong deep discharge resistance and recovery capability, fully meeting the long-term backup and frequent operation demands of substation DC systems.
-
High Compatibility & Stable Output
Standard 2V modular design enables easy assembly into 110V/220V DC power packs, perfectly matching substation control and protection systems. Features low internal resistance for reliable high-current discharge.
-
High Reliability & Long Service Life
Tubular plate structure provides exceptional corrosion resistance. Performance meets or exceeds DIN/GB/IEC standards, making it ideal for high-reliability standby power applications.
III. Applications
- DC operating power supply for substations (control, protection, signaling, and circuit breaker operation)
- Backup power for substation relay protection and automation monitoring systems
- UPS/EPS emergency power supply systems for power plants
- Telecommunications base stations and solar/wind power energy storage systems
IV. Usage Guidelines
- Charging: Float charge voltage: 2.25–2.30V/unit; equalizing charge voltage: 2.35–2.40V/unit. Strictly avoid overcharging or undercharging.
- Discharging: Keep daily discharge depth ≤50% (recommended ≤30% for long-term use). 100% full discharge is strictly prohibited to prevent irreversible damage.
- Environment: Install in a ventilated, dry, and dust-free area. Avoid direct sunlight and high humidity. Operating temperature range: -40~65℃; optimal operating temperature: 25℃.
- Maintenance: Regularly check the electrolyte level and voltage. Replenish electrolyte every 3 years or as required.
