The Woodward BL1840024, also cataloged as the BL1840024 Battery Charger and Power Supply Unit, operates as a dedicated hardware component for industrial battery maintenance and auxiliary DC voltage regulation within power generation platforms.

Hardware Specifications

Harmonic Distortion Suppression and Thermal Heat Sink Dissipation

The Woodward BL1840024 converts 3-phase 360-530 VAC power into a stabilized 24 to 27.5 VDC supply, integrating harmonic distortion suppression filtering to protect sensitive controller circuitry. Built with passive thermal heat sink dissipation profiles integrated directly into the chassis, the unit maintains a continuous 1.5 A charging output without thermal degradation across operating temperatures from -20 to +60 deg C. Its closed-loop regulation maintains precise float and boost charge voltages to optimize battery longevity in high-vibration industrial settings.

Field Installation Guidelines

• Mount the charger vertically against a metal enclosure backplate to maximize convective air flow across the heat sink cooling fins.
• Connect the 3-phase AC mains through a 3-pole circuit breaker, verifying proper phase sequence and terminal tightness.
• Route output DC power lines using twisted pair cables to reduce EMI, maintaining short lead lengths to the target battery bank.
• Ensure a dedicated earth ground cable is securely connected to the main ground stud on the chassis prior to applying AC input power.
