The DELTA BR400W150 is a specialized breaking resistor engineered to protect industrial inverters (VFDs) during switching operations. This critical component safely dissipates energy surges generated when the inverter transitions between states, preventing potential damage to the inverter and connected equipment. With a robust design that operates across a wide input voltage range (40-54-60 Vdc) and supports high current loads up to 10.8 A at full load, the BR400W150 ensures reliable performance in applications requiring precise voltage control and minimal thermal stress. Its compatibility with standard industrial electrical systems makes it a dependable solution for maintaining system stability in demanding environments.
The BR400W150 operates within a precise input voltage range of 40-54-60 Vdc, ensuring compatibility with standard industrial power supplies. At full load, it handles up to 10.8 A of input current, while maintaining a low no-load current of 120 mA at 54 Vdc. The output voltage set point is carefully calibrated to 12.16-12.2-12.24 Vdc when the input voltage is 54 Vdc and the load is open, with a temperature of 25°C. This resistor also supports an output current range of 0-12.5 A and features a terminal configuration of M3.5 x 7 pins rated for 300 V / 20 A. Its exceptional storage temperature range of -55°C to 125°C ensures reliable performance across extreme environmental conditions.
The BR400W150 is designed to manage high-energy switching events without compromising system stability. Its precise voltage regulation ensures consistent output performance even under varying load conditions. The resistor's ability to operate within a wide input frequency range (47-63 Hz) and handle input voltages from 90-264 VAC makes it suitable for diverse industrial power environments. Additionally, the minimal power consumption during no-load conditions (0.3-0.5 W max. at 230 VAC) contributes to energy efficiency in continuous operation.
The DELTABR400W150 is an industrial Breaking Resistor. Selection should be based on the documented characteristics and the requirements of the intended application.
