Yaskawa Electric Corporation CDBR-4045B Dynamic Braking Module

Yaskawa Electric Corporation CDBR-4045B Dynamic Braking Module dissipates regenerative energy from motors during deceleration in AC drive systems, enabling rapid stopping in high-inertia equipment such as conveyors, overhead cranes, hoists, and large rotating machinery. It uses braking resistor control to dissipate energy and includes overvoltage protection and thermal protection integrated with the resistor; the panel-mounted unit is designed for 400V-class drive systems and can be cooled by passive or forced air depending on system design. It is compatible with Yaskawa AC drives and inverter systems, and commonly serves drive system protection, retrofit, and replacement needs. Common replacements include CDBR-4030B, CDBR-4045C, and CDBR-4015B.
