The Yaskawa R7506 model is a highly functional braking resistor, specifically configured for use in the A1000 series drives. Engineered with a heat sink, this product maximizes heat dissipation during operation, improving its longevity and reliability. It operates effectively with an electrical resistance of 300 Ohms.
Designed to accommodate an input voltage ranging from 380 V to 480 V, it is suitable for three-phase AC applications. The component supports a current rating of 5.4 A, enabling it to manage substantial loads with ease. Additionally, the R7506 provides peak braking performance rated at 115%, which ensures its capability to handle transient conditions.
The duty cycle is limited to 3%, which is essential in managing the operational period and preventing overheating. For safety and performance, this braking resistor can maintain functionality in environments with up to 80% relative humidity, as long as there is no condensation present. Similarly, it can be stored in conditions with a maximum humidity of 80% RH.
Lastly, the R7506 is capable of performing efficiently at altitudes reaching up to 1000 meters above sea level, ensuring consistent performance across a range of environmental conditions.
