SC4402-01000 by Danaher

The Danaher SC4402-01000 frequency drive in the NEXTDRIVE Frequency Drives series delivers robust motor control with exceptional braking performance and environmental resilience. Designed and manufactured by Danaher, this drive supplies 1.5 kW (2 HP) continuous power and achieves 200% maximum brake torque for high-inertia loads. A dedicated brake torque duty cycle of 23% enables repeated deceleration cycles without thermal overload. Compact and efficient, the unit supports both TTL and analog signal input types for flexible control integration. Housed in an IP67 rated enclosure, it tolerates dust and water ingress under demanding industrial conditions.

Building on its rugged construction, the SC4402-01000 integrates a brake assembly part number DBA275-230 mated to a brake resistance of 509 ohms at 100% torque. The brake resistor exhibits a minimum R_DB of 150 ohms to maintain safe discharge characteristics. Brake power handling reaches 278 W at rated resistor power and 120 W at 10% duty cycle for precise deceleration. The drive’s physical footprint measures 120 mm x 80 mm x 60 mm, while the companion brake enclosure is 14 x 5 x 4 mm. With a power supply of 12–24 VDC input and voltage class of 380–480 VAC, the system interfaces easily with standard industrial power networks.

In operational terms, the SC4402-01000 sustains performance across an operating temperature range of –40 °C to 85 °C, preventing thermal derating in extreme environments. The integrated brake system ensures uniform stoppage under maximum load, minimizing mechanical shock and wear. Signal compatibility includes both TTL inputs for digital command logic and analog inputs for proportional speed control, enabling adaptable performance profiles. The frequency drive’s duty cycle accommodation supports high-cycle manufacturing processes, conveying reliable deceleration even under continuous operation. Its compact size and lightweight design reduce panel space and simplify mounting without compromising durability.

System integration is straightforward, as the SC4402-01000 is compatible with existing motor control architectures and pairs directly with the DBA275-230 brake assembly. The drive’s IP67 enclosure rating makes it suitable for outdoor installations, washdown applications, and wet-process lines within the industrial automation sector. Specified by machine builders in packaging, material handling, food and beverage, and wastewater treatment, the SC4402-01000 provides a turnkey solution for applications requiring high braking torque, environmental protection, and precision motor control.
