The frequency inverter SPLC-NZS-15G4 is designed for controlling water supply pumps, as well as other asynchronous motors with a power of up to 15 kW with three-phase AC power 380V.
This frequency inverter has a reliable enclosure with IP65 dust and moisture protection, which shields the device's printed circuit boards from dust and water jets when the device is directly installed near actuators in a contaminated environment. The price of the frequency inverter includes its complete set with sealed cable glands, an input cable of 1.8 m for power connection, and an output cable of 1 m for motor connection.
The front panel of the SPLC-NZS-15G4 features an LCD display and indicators, as well as a keyboard. The function of certain keys can be defined via the menu, and they can be locked.
Control circuit terminal blocks:
- 6 multifunctional discrete input terminals, which can be used for remote commands, switching between 16 preset speeds (combination of 4 input signals), between 4 acceleration modes (combination of 2 input signals), etc.;
- 1 analog scalable input (0...10 V, 0...20 mA), which can serve directly as a frequency setpoint source, for connecting a temperature or pressure sensor in closed-loop PID regulation;
- 2 relay outputs;
- 2 analog outputs (0...10 V or 0...20 mA);
- RS-485 (Modbus) for connecting to an industrial process automation system.
The SPLC-NZS-15G4 supports the following control methods:
- scalar control method with multi-point setting capability for obtaining V/f curve.
Main parameters:
- Rated power of connected motor up to 15 kW;
- Output frequency 0.1~400 Hz;
- Ability to operate for 60 seconds with an overload of up to 150% of rated current;
- Manual torque boost 0~20%;
- Carrier frequency selection 1~15 kHz;
- Two counters;
- Possibility of automatic output voltage regulation when supply voltage changes;
- Implementation of multi-step speed programming based on a frequency inverter with 15 steps of different set frequency lasting from 0 to 999.9 s;
- Fine PID regulation settings;
- Support for protection functions from overcurrent, overvoltage, and voltage drop during operation, acceleration and deceleration; from frequency inverter and motor overload; from inverter overheating; from RS-485 communication line break; from feedback break from 4...20 mA sensor; high and low-pressure, water shortage alert.
