Product Description:
Danfoss’s 178B0365 is an AC frequency converter in the VLT 5000 Frequency Converters series. The drive converts fixed three-phase mains power into a variable-frequency output that lets plant controllers regulate motor speed and torque. By adjusting induction motor speed directly, the unit helps optimize conveyors, pumps, and similar process equipment. In control cabinets where footprint and heat dissipation must be managed, the slim, book-style housing simplifies installation. The model serves as a compact, configurable motor control element for general industrial automation tasks.
The internal control board is a process control card, so basic PID functions and setpoint handling take place inside the drive. Power is accepted from a 380–500 V three-phase supply, which aligns with typical low-voltage distribution networks. Under a cyclic overload at 110 percent torque, the inverter can deliver 2.2 kW to the motor shaft. Its book-style housing is rated IP20, providing protection against accidental contact with internal components but no protection from water. Network communication is provided through DeviceNet, allowing straightforward integration with node-addressed fieldbus architectures. A front-mounted display is supplied for parameter entry and status review, and this version includes standard hardware that matches the baseline VLT 5000 mechanical and thermal design.
For heavy startups that demand 160 percent torque, the converter is limited to 1.5 kW, so drive sizing must account for this short-term loading figure. Conducted emissions are suppressed by a Class A1 and Class B filter, enabling installation in mixed-voltage panels without requiring an external filter. The printed circuit assemblies use uncoated circuit boards, which allow easier visual inspection but require clean cabinet air to protect the electronics from moisture and airborne contaminants. The drive has no built-in option, leaving its available slots open for compatible application modules such as specialized input and output interfaces or additional communication protocols.
