This device is a HydraStar HBA-16 Electric-over-Hydraulic (EOH) Brake Actuator.It is an electrically powered hydraulic pump designed to be mounted on a trailer. Its primary purpose is to convert electrical signals from an in-cab brake controller into hydraulic pressure to engage the trailer's disc brakes.
Key FeaturesPerformance: Delivers up to 1,600 PSI of pressure, which is optimal for trailers with disc brakes. Response Time: Offers faster, more responsive braking compared to standard mechanical surge actuators. Construction: Features a sealed, weather-tight, anodized aluminum housing to prevent corrosion in road and marine environments. Reverse Control: Unlike surge systems, it allows for braking while reversing and does not require a manual lockout. Technical SpecificationsPower: 12V DC operation. Fluid Requirements: Compatible with DOT 3 or DOT 4 brake fluid. Wiring: Standard 4-wire setup consisting of: Black: 12V PowerBlue: Brake Controller. SignalYellow: Breakaway SystemWhite: Ground
