The functional and compact scalar frequency inverter SPLC-NLP1000-185G4 is designed for connection to a three-phase network 380 V and control of three-phase asynchronous motors with a power of up to 185 kW. This frequency inverter can control pumps, conveyor belts, and various machines due to fine tuning of motor start and stop, adaptation of the V/f output characteristic to different types of loads, PID regulation, programmable operation using a multi-step PLC instruction, and so on.
The scalar frequency inverter SPLC-NLP1000-185G4 uses scalar V/f control mode. This mode is relatively simple to set up: precise input of all machine parameters is not mandatory.
The scalar frequency inverter model SPLC-NLP1000-185G4 has a protection rating of IP20, so it is recommended to install the device on a DIN rail in specialized cabinets to protect against dust and moisture. If necessary, a remote control panel can be connected to the inverter (not included, supplied on order).

Connection Diagram for Three-phase Scalar Frequency Inverter SPLC-NLP1000-185G4
Power Circuit of Frequency Inverters SPLC-NLP1000-185G4:
- Powered from a three-phase 3ph 380 V AC network 50/60 Hz;
- Linear output voltage is from 0 to 380 V, and the frequency is in the range of from 0.1 to 400 Hz;
- Permissible overload for 60 s — up to 150% of nominal current value (in constant load mode)
Control Circuit SPLC-NLP1000-185G4:
- 4DI — four digital inputs, the function of which can be defined independently through menu selection. For example, a digital input can be used for the start command, forward run, reverse, stop, jumping frequency JOG, switching between frequency sources X and Y, switching between 16 preset speed frequencies, switching between 4 acceleration and deceleration modes, remote frequency increase/decrease, timer start, enabling PID regulation, built-in controller program, etc.
- 1AI — one input that can be switched using jumper J2 and receive the appropriate analogue signal by current 4...20 mA or voltage 0...10 V to set the frequency;
- 1DO — one multifunctional digital output (relay), which can be used for ON-OFF output signal on working status, reaching frequency or timer counter, completion of program step or PLC cycle;
- RS485 — RS485 serial port connector for integration into an industrial set of NL frequency inverter, controllers, industrial PCs, etc.
How to Choose the Right Scalar Three-phase Frequency Inverter Model SPLC-NLP1000 380V?
Since the output voltage of SPLC-NLP1000-185G4 is 380 V, three-phase electric motors 220/380 V need to be connected according to the "star" winding connection scheme. The parameters of the motor corresponding to these connections are specified on its nameplate. The model of the frequency inverter should be selected in such a way that the nameplate values of rated current and power are greater than the parameters of the motor.
