Product Description:

The VACON0100-3L-0038-5-FLOW-R02+IP54 is an AC variable-frequency drive from Danfoss in the VACON 100 Industrial Drives series. It converts fixed AC mains power into an adjustable output for controlling the speed of pumps, fans, and other automated machinery. Designed for wall mounting, the self-contained enclosure integrates the power section, control electronics, and keypad access in a protective shell. The part suffix indicates FLOW firmware, which provides dedicated pump and fan functions such as sleep boost, inlet pressure regulation, and pipe-fill sequences, reducing the need for external control logic in fluid-handling applications.

The nominal output current is 38 A, which is the continuous thermal limit for the connected motor. The housing carries IP54 / Type 12 protection against dust and splashing water. A 3~ mains input connects directly to a balanced industrial three-phase feeder, while conducted emissions remain within Category C2 limits. Full power is available at elevations up to 1000 m without derating. Two analog inputs and one analog output handle process references, and their voltage or current ranges can be scaled independently through the parameter menu. A Form C relay rated for 24 VDC at 8 A can signal external contactors. The internal temperature channel trips when motor-embedded sensors reach 4.7 kΩ with a 3.5 V source. This protective response helps prevent excessive temperatures from damaging the motor or inverter during operation.

An auxiliary supply delivers 24 V at 250 mA for sensors or small actuators. The drive offers 6 programmable digital inputs for run, stop, fault reset, and direction commands. For a potentiometer reference, it provides a stable 10 V output. The analog connections can accept process signals from pressure, flow, or level sensors without requiring a separate interface module. The onboard relay provides a discrete output for alarms, status indication, or contactor control. These control resources allow the inverter to communicate directly with field devices and PLC logic while reducing the need for separate power supplies and signal conditioners inside the control panel.
