Product catalog summary
General Information
The CNP series AC/DC converters are digitally controlled devices designed for powering direct current motors, offering both speed and torque control. They are available in two configurations: bi-directional (four quadrants) for the CNP R and unidirectional (two quadrants) for the CNP U. The converters support a current range from 10A to 3500A and operate with a three-phase power supply voltage from 200Vac to 690Vac.
Simplicity of Installation and Maintenance
The converters feature automatic cycle direction recognition, eliminating the need for sequential power phase connection. A control/programming keyboard facilitates quick calibration and parameter setting. An EPROM on the control card allows for parameter backup and restoration to factory defaults, simplifying maintenance.
Safety and Protections
The CNP series includes programmable electrical protections to ensure reliability. The "automatic switching to armature feedback" function maintains speed control in case of dynamo/encoder failure, preventing dangerous motor racing.
Technology and Performance
With innovative microprocessor technology, the CNP converters offer high performance and easy programming. Predictive control and high processing power provide exceptional speed and precision.
Technical Data
The converters are robustly designed with a metal structure ensuring EMC conformity and feature IP20 protection accessories. They are suitable for severe environmental conditions and include a backlit LCD display for motor control and speed regulation. The interface supports various analog and digital inputs/outputs, making them suitable for complex automation systems.
Communication
Optional cards enable communication with major control systems via RS485 and RS232 serial ports using MODBUS RTU protocol and PROFIBUS DP serial protocol.
Electrical Specifications
The converters support a range of input and output voltages and include protections against short circuits, overcurrent, and overvoltage for safe operation.
Environmental Specifications
  • Operating Temperature: 0°C to 40°C, with a 2% performance downgrade for each degree above 40°C, up to 50°C.
  • Storage Temperature: -25°C to 65°C.
  • Ambient Humidity: 20% to 90% without condensation or water spray.
  • Maximum Altitude: 1000 meters above sea level, with a 1% performance downgrade for every 100 meters above 1000 meters.
Communication Specifications
  • RS 232/485: Optional multidrop, MODBUS RTU protocol, maximum transmission speed of 115.2 Kbps, no parity.
  • Profibus DP: Optional, maximum transmission speed of 12 Mbps.
  • Usage: Connection to terminals, microprocessor cards, PCs, PLCs.
AC/DC Converters
