Mitsubishi GB250H-3F – Industrial Lithium Battery Module | GB Series Platform
Engineering Background
The Mitsubishi GB250H-3F is a high-capacity lithium battery module engineered for mission-critical industrial power backup applications. Designed within Mitsubishi Electric’s GB Series platform, this unit delivers stable, long-cycle energy storage for uninterruptible power supply (UPS) systems, distributed control systems (DCS), and industrial automation infrastructure where power continuity is non-negotiable.
Product Positioning
Targeted at procurement engineers and maintenance teams operating Mitsubishi-based power systems, the GB250H-3F serves as a direct OEM-compatible replacement cell. Its compact form factor, high energy density, and robust BMS integration make it the preferred choice for facilities requiring zero-downtime power assurance in manufacturing, utilities, and process control environments.

System Architecture & Signal Flow
The GB250H-3F integrates directly into Mitsubishi GB Series UPS architectures. The module connects to the host system’s battery bus via OEM-standard terminals. The integrated BMS communicates cell-level state-of-charge (SoC), state-of-health (SoH), and fault status to the host controller via the system’s native communication protocol. During normal operation, the module maintains float charge; upon AC input loss, it transitions to discharge mode within milliseconds, sustaining critical loads until power restoration or controlled shutdown.
Signal Flow: AC Input → UPS Rectifier/Charger → GB250H-3F Module (BMS-managed) → DC Bus → Inverter → Protected Load Output

Technical FAQ
Q: Is the GB250H-3F a direct replacement for the original Mitsubishi unit?
A: Yes. The GB250H-3F is an OEM part number. It is a direct, plug-compatible replacement for GB Series host systems without any modification.
Q: What is the shelf life of an unused GB250H-3F module?
A: When stored at recommended conditions (−20°C to +35°C, 40–60% SoC), the module retains ≥ 80% capacity for up to 12 months. Annual capacity check is recommended for long-term storage.
Q: Can the GB250H-3F be used in parallel configurations?
A: Parallel operation depends on the host UPS system’s architecture. Consult the Mitsubishi GB Series system manual or contact our technical team for configuration guidance.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. CoC and original Mitsubishi documentation are available upon request for all orders.
Q: What are the shipping restrictions for lithium batteries?
A: Lithium battery modules are classified as dangerous goods (UN3480/UN3481). Konmask.com ships in full compliance with IATA, IMDG, and local carrier regulations. Please specify your destination for shipping method confirmation.
