Product Description:

The 195H4101 is an AC drive module manufactured by Danfoss and supplied as part of the VLT 2000 Frequency Converters series. Installed between the mains and a three-phase motor, it generates a variable-frequency, variable-voltage output that enables closed-loop speed control in automated conveyor lines, pump stations, and ventilation systems. By substituting mechanical throttling with electronic regulation, the unit reduces energy consumption and smooths process transitions within industrial automation cells.

At the input stage, the converter presents an apparent power demand of 0.9 kVA, so upstream circuit breakers and cabling can be sized for light-duty feeders. The inverter section supplies a continuous output current of 2.2 A, which is adequate for driving fractional-horsepower induction machines. Motor speed can be increased well above the synchronous base point because the maximum programmable output frequency reaches 500 Hz. During operation, the electronics are housed in an enclosure rated to IP20, meaning fingers are protected from live parts, but the unit must be mounted inside a cabinet in areas with dust or splashing. The drive accommodates motor leads up to 40 m, enabling placement of the control cabinet away from the mechanical load without exceeding recommended cable impedance.

The remaining functional limits align the converter with standard plant environments. Terminal 12 delivers an auxiliary control voltage of +24 V DC for external sensors or contactor coils, eliminating the need for a separate power supply. Heat is removed solely through natural convection, so clearance around the fins is required and no fan is needed. Reliable service is maintained up to an ambient temperature of +40 °C, and output derating is expected above this point. The mains side accepts a line frequency of 50/60 Hz, allowing the same hardware to be used in facilities worldwide without transformer adjustments.
