Product Description:

The 195N0031 is a variable-frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. It regulates the speed of induction motors used in compact process-control systems, including pumps, fans, mixers, and similar machinery. By varying the frequency and voltage delivered to the motor, the drive can match equipment output to changing process demand and reduce unnecessary operation at full speed. Its control functions support coordination with PLCs and other automation hardware, making it suitable for systems that require responsive motor-speed adjustments and process feedback.

The drive delivers a continuous mechanical output of 0.75 kW, which is equivalent to 1.0 HP. It accepts a 200–240 V AC supply through a single-phase input, allowing installation where a three-phase service is unavailable. Integrated thermal and electronic protection helps safeguard internal power components against excessive temperature, current, and operating stress. The housing has an IP20 rating and is intended for cabinet mounting in dry areas with limited exposure to dust or moisture. The standard hardware configuration uses an uncoated control board and does not include an application option card. This arrangement maintains a compact internal layout while retaining the core motor-control functions required for low-power installations.

Conducted electrical noise is reduced by an EN 55011 Class A1 RFI filter, which helps limit interference returned to the incoming power line. The narrow book-style enclosure conserves horizontal mounting space and supports installation in compact control panels. Parameters can be viewed and adjusted through the built-in display (SLCP), eliminating the need for a separate programming panel during routine configuration. The drive is configured for process applications involving flow, pressure, fan speed, and mixing control. Its standard process functions support common PID-based adjustments without requiring a preinstalled application option module. The open VLT architecture also supports integration with distributed automation systems when panel space is limited and centralized control is required.
