The frequency converter SPLC-NZS-0R7G2 is designed to control water supply pumps and other asynchronous motors with a power of up to 0.75 kW under single-phase AC supply 220V.
This frequency inverter has a reliable casing with a dust and moisture protection rating of IP65, which shields the device's circuit boards from dust and water jets when installed directly near actuators in a contaminated environment. The price of the frequency converter includes its equipment with hermetically sealed cable entries, an input cable 1.8 m for connecting the power supply, as well as an output cable of 1 m for motor connection.
The front panel of the SPLC-NZS-0R7G2 features an LCD display and indicators, as well as a keyboard. The function of some keys can be set via the menu, to block them.
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 scalable analog input (0...10 V, 0...20 mA), which can directly serve as a frequency setpoint source, for connecting a temperature or pressure sensor in PID control within a closed loop;
- 2 relay outputs;
- 2 analog 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 the possibility of multipoint adjustment to obtain the V/f curve.
Main parameters:
- Nominal power of connected motor up to 0.75 kW;
- Output frequency 0.1~400 Hz;
- Capability to operate for 60 s with an overload up to 150% of nominal current;
- Manual torque boost 0~20%;
- Carrier frequency selection 1~15 kHz;
- Two counters;
- Capability of automatic output voltage regulation when input voltage changes;
- Implementation of a multi-step speed program from the frequency converter base with 15 steps of different preset frequency lasting from 0 to 999.9 s;
- Fine-tuning of PID control;
- Support for protection functions against overcurrent, overvoltage and undervoltage during operation, acceleration, and deceleration; against inverter and motor overload; against inverter overheating; against communication line RS-485 breakage; against sensor feedback 4...20 mA breakage; alarms for high and low pressure, water shortage.
You can buy a scalar frequency converter Nietz for asynchronous motors with a power of up to 0.75 kW series SPLC-NZS with supply voltage 1PH/220V with delivery to any region in Ukraine.
