Features

Quick Trip Pulse Functionality: Enables rapid shutdown of connected loads in the event of a fault—protecting sensitive downstream equipment.
High Efficiency (Up to 93.8%): Reduces heat generation and energy waste, especially important in compact enclosures with limited airflow.
CAN Bus Galvanic Isolation: Ensures safe and interference-free communication between converter and control systems across separate voltage domains.
High Output Current Capability: Delivers up to 84A at 24V and 42A at 48V in boost mode, supporting heavy-load applications with ease.
Compact & Lightweight Form Factor: At just 327mm deep and under 2kg, it's optimised for high-density rack installations or field-deployed cabinets.
Status LEDs for Local Diagnostics: Tri-colour LEDs indicate system health, warnings, and alarms—providing instant visual feedback for maintenance teams.
