The functional and compact frequency inverter SPLC-NLP1000-1R5G2 is designed for connection to a single-phase network of 220 V and controlling three-phase asynchronous motors with a power of up to 1.5 kW (depending on the selected model of the frequency inverter). This frequency inverter can control pumps, conveyor belts, and various machines thanks to fine-tuning of motor start and stop, adaptation of the V/f output characteristic for different types of loads, PID regulation, programmable operation according to multistep PLC instructions, etc.
The scalar frequency inverter SPLC-NLP1000-1R5G2 uses a scalar V/f control mode. This mode is relatively simple to set up: precise entry of all machine parameters is not obligatory.
The scalar inverter model SPLC-NLP1000-1R5G2 has a protection rating of IP20, and it is recommended to be installed on a DIN rail in specialised cabinets for protection against dust and moisture. If necessary, a remote control panel can be connected to the inverter (not included in the price, supplied on order).

Connection diagram for inverter SPLC-NLP1000-1R5G2
Power circuit of frequency inverters SPLC-NLP1000-1R5G2:
- Powered from a single-phase network 1ph 220 V AC 50/60 Hz;
- The linear output voltage ranges from 0 to 220 V, and frequency is in the range from 0.1 to 400 Hz;
- Permissible overload for 60 s is up to 150% of the nominal current (under constant load mode)
Control circuit SPLC-NLP1000-1R5G2:
- 4DI — four digital inputs, whose function can be defined independently through menu selection. For example, a digital input may be used for a start command, forward run, reverse, stop, JOG frequency skip, switching between frequency sources X and Y, switching between 16 preset speed frequency values, 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 analog signal in current 4…20 mA or voltage 0…10 V to set the frequency;
- 1DO — one multifunctional digital output (relay), which can be used for output signal ON-OFF about working state, reaching frequency or timer, step or cycle completion of PLC program;
- RS485 — RS485 serial port connector for integration into an industrial set of frequency converters NL, controllers, industrial PCs, etc.
How to choose the right single-phase scalar inverter model series SPLC-NLP1000 220V?
Since the output voltage of SPLC-NLP1000-1R5G2 is 220 V, three-phase electric motors 220/380 V should be connected using the "delta" winding connection scheme. The relevant parameters for this connection are indicated on the motor plate. The frequency inverter model should be chosen so that the nominal current and power table values are greater than the motor parameters.
