The compact multifunctional frequency inverter Nietz SPLC-AT20-0R4G2 is designed for connection to a single-phase network 220 V and controlling three-phase asynchronous motors with power up to 0.4 kW. These frequency inverters are used to control conveyors, machine drives, and other loads where it is necessary to maintain torque over a wide range of engine speeds with low and infrequent overloads.
The frequency inverters SPLC-AT20-0R4G2 with power up to 0.4 kW use by default vector control mode V/f.
The frequency inverter models SPLC-AT20-0R4G2 have an IP20 protection grade, so they are recommended to be mounted on a DIN rail in specialized cabinets to protect against dust and moisture. The removable control panel, located on the front of the cabinet, simplifies configuration.

Functions of Frequency Inverters SPLC-AT20-0R4G2:
- The specified output frequency can be a digital parameter, received in the form of an analog current signal (or voltage), pulse. The construction of control inputs of the frequency inverter allows you to choose the type of input signal: NPN or PNP;
- The selection of the main frequency source of channel X and the additional Y channel, calculation operations (addition, subtraction, maximum, minimum), as well as switching between sources;
- Up to 15 digital frequency settings for timed startup with a step of 0 to 6500 seconds or from 0 to 6500 hours (the unit of time is selected in the settings);
- Control of multiple pumps or fans in V/f mode;
- Selection of V/f control frequency characteristic: normal linear, multipoint, square, or with coefficients 1.2, 1.4, 1.6, 1.8;
- Linear and S-curve acceleration-deceleration characteristics;
- Automatic and manual torque boost by 0...30 %;
- Motor stop by DC braking;
- Automatic voltage regulation (AVR);
- Sleep mode, switch on during sleep to protect the water supply system from freezing;
- JOG mode;
- User password query function to access the inverter menu
Delivery Set
- Vector frequency inverter of the AT series
- Removable control panel (mounted on the frequency inverter)
Advantages
- The frequency inverters of the SPLC-AT20-0R4G2 series have a high-performance processor and various functions that allow precise control of low-power motors
