H.7001B -25 is a part of Pawbol, an electric motor controller and charger. It is a two-phase, full-wave bridge motor control module designed to provide speed control, direction control, and current limit protection for two-phase Brushless DC (BLDC) motor systems. H.7001B -25 is constructed with specialized power semiconductors and components mounted on a compact, single-piece printed circuit board (PCB). Its features include a maximum DC link voltage of 280 volts, current capability up to 25 amps, adjustable high/low voltage protection, adjustable current limiting, and a resistive fault protection. Additionally, the module provides protection functions including over-voltage protection (OVP), under-voltage protection (UVP) and a 6-pulse phase-shifted topology for improved current waveform quality and reduced interference.
