Multi-functional frequency inverters of the SPLC-AT20-2R2G2 series are designed for connection to a single-phase network 220 V and control of three-phase asynchronous motors with power up to 2.2 kW (depending on the selected model of the frequency inverter). 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.
Frequency inverters SPLC-AT20-2R2G2 with power up to 2.2 kW use vector control mode V/f by default.
The models of frequency inverters SPLC-AT20-2R2G2 have a protection rating of IP20, so it is recommended to install them on a DIN rail in specialized cabinets for protection against dust and moisture. The removable control panel, located on the front panel of the cabinet, simplifies setup.

Functions of frequency inverters SPLC-AT20:
- The specified output frequency can be a digital parameter, come in the form of an analog signal of current (or voltage), pulse. The design of the control inputs of the frequency inverter allows you to choose the type of input signal: NPN or PNP;
- Selection of the main frequency source channel X and additional Y channel, calculation operations (sum, difference, maximum, minimum), and switching between sources;
- Up to 15 digital frequency settings for timed start with a step from 0 to 6500 seconds or from 0 to 6500 hours (time unit is chosen in settings);
- Control of multiple pumps or fans in V/f mode;
- Selection of frequency characteristic V/f control: standard linear, multipoint, quadratic, or with coefficients 1.2, 1.4, 1.6, 1.8;
- Straight-line and S-curve acceleration-braking characteristics;
- Automatic and manual torque boost 0...30%;
- Stopping the engine by DC braking;
- Automatic Voltage Regulation (AVR);
- Sleep mode, activation during sleep to protect the water supply system from freezing;
- JOG mode;
- User password request function for access to inverter menu
