CV50
Salicru's Controlvit CV50 variable frequency drive series covers power ratings that range from 0.75 kW to 500 kW. They are suitable for both constant and variable torque applications (power duality), and therefore allow the costs of the system to be optimised by adapting to the type of load to be regulated.
They stand out for their design, reliability, ease of use and versatility, being suitable both for low-power applications, where it is necessary to have good control precision, and high-power applications, where it is important to maintain the appropriate torque and ensure continuity of operation.
Thanks to their automatic energy-saving function, they achieve significant consumption reductions, mainly in ventilation, water treatment and irrigation applications.
The CV50 is a dual inverter, meaning that it can work in constant and variable torque applications. For this reason, they are suitable for use in the following applications: pumps, fans, HVAC applications, compressors, extruders, mills, presses, mining industry and machinery in general.
The CV50 features an optional advanced LCD keypad that can replace the device’s standard LED keypad.
It has 10 lines of information, and contains a brief explanation of each of the drive’s parameters and different options.
Its language can be set to English or Spanish and its parameters can be copied from one drive to another.
It can also be connected and disconnected without the need to turn off the drive.
This enables the drives to be connected to a PC, configured and monitored to facilitate commissioning and maintenance.
Features:
- Import and export of drive parameter setting files.
- Display and modification of parameters.
- Quick comparison between programmed and default parameters.
- Oscilloscope with up to 10 channels, with data storage, export, etc.
- Multiple monitoring: one PC can monitor different drives at the same time.
They feature multi-step speed control, which enables the frequency setpoint to be selected by combining four multifunction inputs, obtaining up to 16 possible speeds.
In addition, using the simple PLC function, the CV30 and CV50 series enable the same 16 steps and their duration to be set, but without the need to use combinations of inputs. It is also possible to choose between performing the cycle repeatedly or carrying it out once.
This function, in many cases, removes the need to install an external control element.
- The CV50 inverter enables the creation of a pressure unit with up to three pumps (main pump + two fixed auxiliary pumps).
- By means of a signal provided by the transducer, automatic PID pressure control is performed.
- The setpoint can be set via keypad, an analogue signal or RS485 Modbus communication.
- Features two level parameter setting modes for sleep or wake: % of sensor pressure or by frequency.
All drives include a Modbus RS-485 communication port, which allows communication with other devices such as PCs, PLCs, HMI, SCADA systems, etc.
The Modbus system is the most widespread in the industry, and has the greatest availability for the connection of industrial electronic devices.
The CV30 and CV50 series are equipped with a meter to measure the kWh consumed by the drive. This metering can be stopped in the event of testing, setting an initial value, resetting and accessing it via Modbus communication.
