DANFOSS VLT2822PT4B20STR1DBF00A00C0 195N1051 VLT2800 Variable Frequency Drive

Overview

The DANFOSS VLT2822PT4B20STR1DBF00A00C0, order code 195N1051, belongs to the discontinued VLT 2800 series general-purpose AC drive. The DANFOSS VLT2822PT4B20STR1DBF00A00C0 accepts 3-phase 380–480 V AC input and supplies variable frequency and voltage output for 2.2 kW (3 HP) asynchronous motors. This unit is fitted with built-in RFI Class A1 filter, local SLCP keypad display, no fieldbus card and no conformal coating. It is widely used for fan, pump, conveyor and packaging machine speed regulation, and is a common spare for legacy automation retrofits.

Features

The DANFOSS VLT2822PT4B20STR1DBF00A00C0 supports V/F control and open-loop motor control for standard induction motors. The DANFOSS VLT2822PT4B20STR1DBF00A00C0 comes with integrated EN 55011 Class A1 RFI filter to reduce conducted interference. It has an integrated local keypad and display for parameter setup and fault reading. Standard digital and analog I/O terminals are available for connection with sensors, PLC and external control signals. Book-style IP20 housing fits cabinet panel mounting. The model is end-of-life, so matching spare replacement is required for existing VLT2800 systems.

Principle

The DANFOSS VLT2822PT4B20STR1DBF00A00C0 converts three-phase fixed-frequency AC into DC through the rectifier bridge, then uses IGBT inverter to generate adjustable frequency and voltage for motor speed control. The internal control loop follows the reference signal from keypad, analog input or digital terminals. The built-in RFI filter suppresses high-frequency interference back to the mains. When abnormal conditions are detected, the drive blocks output pulses and displays fault codes for troubleshooting.

Applications

The DANFOSS VLT2822PT4B20STR1DBF00A00C0 is deployed on fans, water pumps, conveyors and packaging equipment in factory automation skids. The DANFOSS VLT2822PT4B20STR1DBF00A00C0 is stocked as spare part for emergency replacement and maintenance of legacy VLT2800 drive systems. For new projects, Danfoss FC280 Midi Drive is the recommended replacement platform.
