195H3403

The Danfoss 195H3403 frequency converter is a compact, high-performance drive within the VLT 2000 Frequency Converters series designed for three-phase industrial automation applications. It delivers a nominal Output Power: 1.5 kW and sustains a Constant Output Current: 4.0 A to drive medium-duty motors with precision. The converter accepts a wide Input Voltage: 3 x 380–460 V AC range, enabling compatibility with standard industrial power grids. Its selectable Output Frequency Range: 0–120 Hz or 0–500 Hz offers flexible speed control for diverse load profiles. Integrated Thermal Protection: Integrated Electronic ensures reliable operation under full-load conditions.

The technical architecture of the 195H3403 is defined by robust electrical and environmental specifications. The Enclosure Rating: IP20 permits installation within control cabinets and shielded panels. Vibration-free performance is supported by an EMC Emission Standard: EN 55011 Group 1 Class A (with filter), ensuring compliance with industrial RFI requirements. Safe transport and storage are maintained within the Storage Temp Range: –25°C to +70°C, while operational longevity is guaranteed at an Ambient Temp (full Load): 0°C to +40°C. Cabling flexibility is addressed by a Max Cable Length (unscreened): 40 m (extendable to 300 m with external IP10 coil). Mechanical dimensions are optimized for rack density with Dimensions With 100 Mm Module: A=462 mm, a=437 mm. Overload and fault scenarios are mitigated via Overcurrent Protection: Protected against ground and short circuit.

Operational features of the VLT 2030 type converter emphasize precision and reliability. The digital control platform modulates output frequency with high resolution for smooth torque delivery across the 0–500 Hz span. Built-in electronic thermal monitoring continuously regulates heat dissipation, preserving component life and avoiding unexpected derating. Dynamic braking and current limiting respond instantly to transient loads, maintaining stable motor speed under varying torque demands. The IP20 enclosure and filter options reduce electromagnetic interference, enabling clean operation in dense control environments.

System integration is streamlined for the 195H3403 through standard drive protocols and plug-and-play compatibility with Danfoss accessories. Side-by-side mounting with zero minimum side clearance maximizes cabinet utilization in space-constrained installations. The drive’s naming convention within the VLT 2000 series simplifies inventory management and documentation in complex automation projects. Target applications include conveyor systems, pumps, fans, and general-purpose machinery where reliable speed control and compact form factor are critical.
