Ecumaster Dual H-Bridge

Ecumaster Dual H-Bridge

The Ecumaster Dual H-Bridge is a high-performance, solid-state power module designed to provide bidirectional control for DC motors and high-current actuators. In modern motorsport, many components—such as Electronic Throttle Bodies (DBW), variable valve lift mechanisms (like BMW Valvetronic), and electric window motors—require precise duty cycle control and the ability to reverse polarity. The Dual H-Bridge provides this capability in a compact, rugged package, acting as a high-current amplifier for your ECU or a standalone CAN-controlled controller.

Housed in a premium CNC-machined aluminium enclosure, the module is engineered for superior heat dissipation and reliability in high-vibration environments. It features two independent H-Bridges, each capable of delivering 10A continuous and 30A peak current. Whether you need to drive multiple ITBs, manage high-current fans, or expand the output capabilities of your Ecumaster PMU or EMU Black, this module offers the technical authority required for professional-grade power management.

Technical Authority & Key Features

• Dual Independent Channels: Two separate H-Bridges allow for the simultaneous, independent control of two DC motors or four high/low-side outputs.

• Bi-Directional DC Motor Control: Each bridge can supply protected Low Side (GND) or High Side (VBat) supply independently to manage motor direction and speed.

• High Current Capacity: Engineered for heavy loads with 10A continuous and 30A peak current per bridge, ensuring it handles high-inrush currents without failure.

• Integrated Safety Protection: Built-in over-current and short-circuit protection safeguards both the module and your expensive actuators.

• Flexible Control Logic: Can be triggered via 4 physical analog/digital inputs (0-5V or PWM) or fully managed over a CAN BUS network.

• Precision PWM Output: Features a 12-bit, 3.9kHz to 20kHz PWM frequency for ultra-smooth motor operation and precise positioning.

• Multi-Bridge Pairing: For extreme applications, the H-Bridge outputs can be paired to double the current handling capacity.

• Rugged Thermal Management: The CNC Billet Aluminium casing ensures the unit stays within optimal operating temperatures even under high duty cycles.
