Product Description:
The 195H4103 is a frequency converter produced by Danfoss for the VLT 2000 Frequency Converters series. It is used in industrial automation to vary the voltage and frequency applied to small induction motors, enabling process-matched speed control and energy savings across pumps, fans, and light material-handling equipment.
The control board supplies an analog reference of 10 V DC for potentiometer speed commands, while discrete logic is powered from 24 V DC. Under rated conditions the inverter can deliver a constant motor phase current of 3.1 A and generate output frequencies as high as 500 Hz, even though the matched motor is expected to run continuously at 100 Hz. Acceleration and deceleration profiles are adjustable, with a maximum ramp time of 800 s to protect against current surges when starting high-inertia loads. Protective wiring guidelines call for a 16 A pre-fuse on single-phase 230 V mains, and the digital inputs require a pull-up resistor of at least 600 Ω. Typical apparent output power reaches 1.3 kVA at 230 V.
The plastic housing is rated IP20, so the unit must be mounted inside a switchgear enclosure where relative humidity can be as high as 95 %. Line fluctuation tolerance is limited to ±10%, and the terminal set accepts conductors up to 4 mm² for both mains and motor leads. Under these conditions the drive provides a typical mechanical shaft output of 0.55 kW. These capabilities position the converter for long-duty applications that demand reliable speed regulation without external braking or complex thermal management.
