Frequency Inverters 0.4 kW

Low-power frequency inverters (LPF) 0.4 kW (400 W) are used in small systems:

• pumps,
• fans,
• conveyors
• small machines.

Frequency inverters can also be used in heating, ventilation, and air conditioning (HVAC) systems. Inverters with a power rating of 0.4 kW convert alternating current (AC) into direct current (DC) and then back to AC at a different frequency. This allows for smooth speed control of small power asynchronous electric motors of 0.4 kW.

The main advantages of low-power inverters include energy savings through optimisation of drive speeds, smooth start and stop of motors, overload protection, easy installation and setup. Low-power frequency inverters are available both as separate modules and as part of complete control cabinets.

Popular series of low-power inverters: NIETZ AT20 0.4kw, ESD 400w, ESD2 400 w, NLP 400W and FC1000 0.4 kW. The choice of a specific model depends on the required functions, power range, control method: vector or scalar, application area, cost, and other factors.
