The frequency converter SPLC-NZS-2R2G2 is designed for controlling water supply pumps and other asynchronous motors with power up to 2.2 kW with single-phase AC power 220V.
This frequency converter has a reliable enclosure with a dust and moisture protection rating of IP65, which protects the device's printed circuit boards from dust and water jets in environments where it is installed directly next to actuators in polluted conditions. The price of the frequency converter includes its equipment with hermetic cable entries, an input cable 1.8 m for power connection, as well as an output cable 1 m for motor connection.
The front panel of the SPLC-NZS-2R2G2 features an LCD display and indicators, as well as a keyboard. The function of some keys can be defined and locked via the menu.
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), among 4 acceleration modes (combination of 2 input signals), etc.;
- 1 scalable analogue input (0...10 V, 0...20 mA), which can directly serve as a set frequency source, for connecting a temperature or pressure sensor under PID control in a closed loop;
- 2 relay outputs;
- 2 analogue outputs (0...10 V or 0...20 mA);
- RS-485 (Modbus) for integration into an industrial process automation system.
SPLC-NZS supports the following control methods:
- Scalar control method with multipoint setup for obtaining the V/f curve.
Main parameters:
- Rated power of connected motor up to 2.2 kW;
- Output frequency 0.1~400 Hz;
- Capability to operate for 60 seconds with overload up to 150% of nominal current;
- Manual torque boost 0~20%;
- Carrier frequency selection 1~15 kHz;
- Two counters;
- Ability to apply automatic output voltage control in cases where supply voltage changes;
- Implementation of multi-step speed program based on the frequency converter with 15 steps of different set frequency duration from 0 to 999.9 s;
- Fine PID control settings;
- Support for protection functions against overcurrent, overvoltage, and undervoltage during operation, acceleration, and deceleration; against overloading of the frequency converter and motor; against converter overheating; against communication line disconnection RS-485; against feedback disconnection from sensor 4...20 mA; high and low-pressure alarms, water shortage.
