134H2362 by Danfoss

The 134H2362 is an AC variable-frequency drive from Danfoss that belongs to the VLT 2800 Low Voltage Drives series. This controller modulates the speed of small induction motors used in process equipment, improving energy efficiency and torque regulation. The unit is intended for panel installation where machinery requires tight speed control. By converting fixed mains power into a controllable output frequency, the drive supports automated conveyors, mixers, and similar industrial tasks. This operating method also allows motor speed to follow changing process demand more closely during normal production.

The drive accepts an input line of 200-240 V AC and is wired for a single-phase supply, making it suitable for facilities that lack three-phase service. Its integrated RFI filter satisfies EN 55011 Class A1, which helps limit electromagnetic interference on adjacent instrumentation. For supervisory control, the communication slot is populated with Profibus DP 12 MBaud, allowing setpoint, status, and diagnostic data to be exchanged with PLC networks. This network connection supports centralized monitoring and command handling during operation. The housing carries an IP20 rating, so live parts are finger-safe when the unit is mounted inside a closed cabinet.

The mechanical form factor follows a book-style outline, so multiple units can be stacked with minimal cabinet depth. External surfaces have a coating finish to resist humidity and airborne contaminants common in processing areas. The drive is standard with a brake, meaning a built-in brake chopper is available for controlled deceleration of high-inertia loads. This feature helps manage regenerated energy during stopping and speed reduction. Operators interact through the built-in display (SLCP), which shows speed, current, and fault codes directly on the unit. The display also allows local review of operating values without adding a separate external interface.
