195N2190 Danfoss VLT 2800 Series 1.5kW Frequency Converter

Product Overview

The 195N2190 (195N2190) is a high-performance variable frequency drive from the legacy Danfoss VLT® 2800 series, specifically the VLT 2915 model. Rated at 1.5 kW (2.0 HP), this drive is recognized for its ultra-compact "side-by-side" design, which allows for maximum space efficiency in control cabinets. The 195N2190 is engineered for versatility, providing reliable speed control for three-phase asynchronous motors across various industrial applications. With an integrated brake chopper and a robust hardware build, this frequency converter serves as a dependable solution for conveyor systems, packaging machinery, and small-scale pumping operations where reliability and ease of integration are paramount.

Suffix & Code Breakdown

• VLT 2915: Indicates the model size within the VLT 2800/2900 family, optimized for 1.5 kW loads.

• T4: Three-phase input designed for a mains voltage range of 380 - 480 VAC.

• B: Integrated Brake Chopper included, allowing for dynamic braking when used with an external resistor.

• 20: Protection rating of IP20 (Chassis/Open type), requiring installation in a protected electrical panel.

Technical Specifications

Technical FAQs

How does the "Side-by-Side" mounting benefit my cabinet design?

The 195N2190 features a specialized thermal design that allows multiple units to be mounted directly against one another without air gaps. This "bookstyle" installation significantly reduces the total width required in the electrical panel, allowing for more drives in a smaller footprint.

What is the purpose of the built-in brake chopper in the 'B' version?

The integrated brake chopper allows the drive to handle regenerative energy from a motor during rapid deceleration. By connecting an external braking resistor to the drive, you can prevent "Overvoltage" trips and achieve faster, more controlled stopping times for high-inertia loads.

Is this drive compatible with standard PLC protocols?

Yes. The VLT 2800/2900 series typically supports RS485 communication with Danfoss FC Protocol or Modbus RTU as standard. This enables the 135N2190 to be integrated into centralized control systems for remote speed adjustment and status monitoring.

Engineering & Installation Guide

• Thermal Clearance: While side-by-side mounting is supported, the drive still requires vertical clearance. Maintain at least 100 mm of free space above and below the unit to ensure adequate airflow through the internal cooling fans and heat sink.

• Cable Shielding: To ensure electromagnetic compatibility (EMC), use shielded motor cables. The shield should be grounded at the drive using a metal decoupling plate or 360-degree clamp to reduce high-frequency noise interference with nearby control electronics.

• Commissioning Tip: During setup, ensure the motor data (Voltage, Frequency, Current) from the nameplate is accurately entered into the parameter group 100. For best performance, perform an Automatic Motor Tuning (AMT) to allow the drive to optimize its internal VVC+ (Voltage Vector Control) algorithm for your specific motor.
