Product Description

The S74801-NA servo digital amplifier is an integral component in Kollmorgen's lineup, exemplifying their commitment to combining precision control with robust performance suitable for a vast array of industrial applications. This particular digital amplifier operates within a rated supply voltage from 208V to 480V, adaptable to a variety of global industrial power standards, and handles a substantial rated input power of 35 kVA for S1 operation, allowing for continuous duty and high performance. Versatility is at the heart of the S74801-NA's design, capable of handling a switch on/off frequency of 30 times per hour, providing users with the flexibility required for demanding production schedules. It's adept in delivering a consistent rated output current of 48 Arms across a broad voltage range, ensuring optimal performance and reliability. Furthermore, for applications demanding short bursts of power, it offers a peak output current of 96 Arms for approximately 2 seconds. The drive's switching frequency of the output stage is set at 8 kHz, which aids in minimizing electrical noise and allows for smooth power modulation, critical in precision-driven tasks. With a minimum motor inductance of 0.38 mH at 208V and a maximum noise emission of a mere 62 dB(A), the S74801-NA operates with discretion, preventing disturbances in noise-sensitive environments. Thermal efficiency is also a highlight, with the digital amplifier capable of dissipating up to 685W at 480V without brake dissipation, which speaks to its ability to manage heat effectively during intensive operations. The mechanical design boasts a compact footprint, with a width of 190mm and a depth of 243mm without connectors, allowing for integration into systems where space is at a premium. Safety is not an afterthought with the S74801-NA, which complies with a series of international safety and quality standards such as ISO 13849, IEC 60204, and IEC 61508, ensuring that it meets the stringent requirements for safety-related parts of control systems. These standards cover aspects from the basic concepts for design to the functional safety of electrical/electronic/programmable electronic safety-related systems.
