V7768-320000 3509301007768-320000A0 | GE Electric DC Backup Battery Module
Product Description
The GE V7768-320000 (3509301007768-320000A0) is a High-Integrity DC Backup Battery Module designed for uninterrupted power supply in critical industrial control systems. It ensures continuous operation of safety controllers (e.g., Mark VIe) during mains power failures by delivering regulated DC power, enabling safe shutdowns, data retention, and system stability.
Key Features
- Extended Runtime: Nickel-Cadmium (NiCd) chemistry for 8+ hours of backup at full load.
- Hot-Swappable Design: Allows replacement without system shutdown.
- Intelligent Monitoring: Onboard voltage/current sensors with fault alerts via control network.
- SELV Compliance: Safety-Extra Low Voltage (60V DC) for reduced arc/flash risks.
- Corrosion Resistance: Sealed IP65 enclosure for harsh environments (dust, humidity, chemicals).
- Zero Maintenance: Non-spillable construction with 10-year design life.
