Technical Specifications Main power input from drive internal power loop. Auxiliary signal interface. Typical power consumption 6.3 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated circuit board surface.
Functional Features Monitors main power supply voltage status of drive unit. Provides short‑time backup power for control logic circuit when main power is lost. Generates power‑failure warning signal for main control board. On‑board LED indicates power and fault status. Built‑in hardware self‑diagnosis function.
Application Scenarios Serves as internal spare‑part for ABB industrial frequency converter. Used for drive equipment maintenance, overhaul and spare‑part replacement.
Performance Parameters Provides stable short‑time backup power output. Rapidly detects main power supply drop‑off event. Conformal coating improves moisture‑proof and dust‑proof performance for cabinet internal environment.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Power monitoring chip, energy buffer components. Conformal protective coating layer. Multi‑pin plug‑in connectors.
Structural Characteristics Internal plug‑in circuit board structure matched with drive cabinet slot. Board edge equipped with multi‑pin plug‑in connectors. Reserved mechanical fixing holes. Weight approximately 0.52 kilogram.
Working Principle Under normal main‑power condition, board monitors power voltage and completes energy storage. When main power supply drops, stored energy releases and supplies backup power to drive control circuit. Power‑failure alarm signal is sent to main control board meanwhile. On‑board LED reflects hardware running status continuously.
Installation Requirements Fully cut off frequency converter main power and control power before replacement. Insert TPPB‑02 board into designated internal slot and fasten fixing screws. Confirm connectors are fully engaged. Restore power supply after installation and verify power‑failure detection function.
Usage Notes Carry out anti‑static protection during disassembly and assembly. Do not scratch conformal coating surface. Strictly cut off all power source before board plug‑in operation. Complete function test after spare‑part replacement.
