Product Description:

The 195N0073 is a low-voltage AC drive from Danfoss that belongs to the VLT 2800 Low Voltage Drives series. It modulates three-phase mains power to regulate induction motor speed in conveyors, pumps, and fan systems, allowing closed-loop torque control without mechanical throttling. Its mass is 6.0 kg, so the drive can be mounted directly on standard DIN rails or backplates without additional bracing.

An operating efficiency of 95% limits wasted energy to 5 percent, which keeps internal heating low and simplifies cabinet ventilation. Under nominal load, the converter draws a rated input current of 14.7 A and supplies a rated output current of 16 A; these values support cable sizing and breaker selection for continuous service. A true power factor of 0.90 keeps reactive demand modest on the supply network. For overloads or acceleration events, the input current can reach 23.5 A, while the inverter section can momentarily deliver 25.6 A. These current levels help the drive start high-inertia machinery without nuisance trips. When the unit operates at full capacity, resistive and switching losses amount to 231 W, and this heat must be removed through panel airflow.

The power stage is rated at 0.75 kW and is protected by an enclosure classified as IP20, which prevents finger contact with hazardous internal components but does not provide protection against liquids. Supply circuits upstream must be fused at 25 A according to IEC or UL guidelines, and the internal design withstands fault currents up to 100,000 A when coordinated with suitable circuit breakers. Both motor and mains conductors connect to spring terminals that accept 4 mm² (AWG 10) cable, providing the same copper cross-section on the input and output sides. The dedicated ground connection accepts the same conductor size, helping maintain consistent impedance and minimize common-mode electrical noise on the motor lead.
