Product Description:

The 195N0074 is a low-voltage variable frequency drive built by Danfoss for the VLT 2800 Low Voltage Drives series. By converting fixed-frequency three-phase mains power into a pulse-width-modulated output, the unit enables induction motors to start gently, match changing load demands, and stop quickly under control. This performance supports conveyors, pumps, and other factory equipment that require adjustable speed while fitting into compact control cabinets. Relay interfaces reduce the need for separate control components in these installations.

The drive supplies 1.0 HP at the shaft and reaches 95% efficiency, so most of the incoming power is delivered to the motor rather than lost as heat. The line input draws 14.7 A during continuous operation, while the inverter section maintains a rated output of 16 A for steady torque production. The molded housing carries an IP20 rating, indicating finger-safe openings but no protection against water. The drive includes an integral brake transistor; with a recommended 25 Ω resistor, it permits regenerative energy to be dissipated for as long as the 120-second intermittent duty cycle allows, helping the load decelerate without overvoltage trips. A 25 A prefuse value is suggested to coordinate branch-circuit protection with these electrical limits.

Short-duration overloads are accommodated by elevated current and braking margins. For 60-second events, the output can rise to 25.6 A, and high regenerative spikes are absorbed by the brake chopper at levels up to 3.00 kW. The external brake element must not fall below 22 Ω to prevent excessive thermal stress. Internally, the control PCB monitors heat flow; a thermal relay set at 11.0 A and a power-loss ceiling of 231 W together establish the shutdown threshold.
