VLT 3042

The VLT 3042 variable speed drive from Danfoss represents a member of the VLT 3000 Variable Speed Drives series, delivering robust performance for industrial automation applications. This drive supports a Power Rating (constant Torque): 30 kW with an impressive Efficiency at 100% Load: 0.96, ensuring minimal energy waste under full load conditions. It accepts an Input Voltage: 3 x 380/400/415 V ±10% power supply and is capable of driving motors with a Max Motor Cable Length: 300 m (unscreened), 150 m (screened). Designed to operate even in high humidity environments, it meets the requirements of DIN 40040 Class E with relative humidity up to 95%. With a Max Cable Cross Section (input/output): 35 mm², it accommodates heavy gauge cables for optimal power delivery.

Performance optimization is achieved through an adjustable Supply Frequency: 50/60 Hz and an input switching frequency set at 5 kHz by default. The drive features a wide acceleration and deceleration range of 0.1 to 3600 seconds, allowing custom motion profiles for various machinery. It delivers a Output Current (constant Torque): 61 A and Output Current (variable Torque): 73 A, with surge capability to a Max Output Current (60s, Ct, 230 V): 97.6 A. Output power ratings include Output Power at 415 V (ct): 43.8 kVA and Output Power at 415 V (vt): 52.5 kVA, complemented by a Power Factor (cos φ): 0.9/1.0 to maximize throughput. The unit’s Overload Protection incorporates integrated thermal protection and thermistors per DIN 44081 standards, while built-in ground fault and short-circuit protection ensures operational safety.

Engineered for reliability in harsh industrial environments, the VLT 3042 operates across an Ambient Temperature Operation: –10 to +45°C (CT) range without derating, and withstands vibration up to 0.7 g. The drive’s Power Loss at Max Load: 1110 W highlights efficient thermal management, reducing cooling requirements and maintenance intervals. It seamlessly integrates into existing automation architectures via industry-standard communication protocols and mounting dimensions consistent with the VLT 3000 family. The drive’s resilience to wide humidity and temperature variations, plus its compact form factor and robust construction, render it ideal for pumps, fans, conveyors, and mixers in water treatment, HVAC, and general manufacturing sectors.
