Key Engineering & Operational Features

Why electrical consultants, industrial plants, and utility engineers specify MOBY AMF Panels (Auto-Main Failure Panels).

⚡

Zero Loss of Work & Production

Automatic sensing transfers the full plant load from mains to backup generator in seconds, eliminating costly machinery halts and process interruptions.

🔒

Dual Mechanical & Electrical Interlocking

Positive mechanical interlock links and electrical coil interlocks make it physically impossible for Mains and Generator sources to parallel, avoiding catastrophic backfeeding.

🔋

Built-In Intelligent Battery Charger

Constant-potential, current-limiting SMPS charger keeps the DG starting battery fully charged at all times, preventing start failures during winter or prolonged grid health.

⏱️

Programmable Engine Cool-Down

When mains power is restored, the panel transfers load back to the grid but keeps the DG idling unloaded for 3 minutes to dissipate thermal stress before shutting down.

🎛️

Multi-Mode Flexibility (Auto/Manual/Test)

Operators can initiate weekly off-load test runs, execute emergency manual changeovers via front handles, or leave the system in fully autonomous Auto mode.

🚨

Audio-Visual Fault Annunciation

Comprehensive LED mimic indicators and high-decibel hooter alert maintenance personnel to phase failures, trip events, or engine faults instantly.
