The multifunctional frequency inverter Nietz SPLC-AT20-0R75G2 is designed for connection to a single-phase network 220 V and control of three-phase asynchronous motors 220V with a power of up to 0.75 kW (depending on the selected frequency inverter model). These frequency inverters are used to control conveyors, machine drives, and other loads where maintaining torque across a wide range of motor speeds with low and infrequent overloads is necessary.
The frequency inverter SPLC-AT20-0R75G2 with power up to 0.75 kW uses the default vector control mode V/f.
The model of frequency inverter SPLC-AT20-0R75G2 has a protection degree of IP20, so it is recommended to install it on a DIN rail in specialized cabinets to protect against dust and moisture. The removable control panel located on the front panel of the cabinet facilitates setup.

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