ERMAN E-9 5R5T4, 055T4, 132T4, etc.

• Frequency converters for pumps and fans use a modern algorithm of sinusoidal pulse-width modulation, withstand high operational overloads, allow you to obtain rated torque at low motor speeds, compensate for the torque at a loaded start and control the volt-frequency response of the electric motor.
• They automatically compensate for torque and sliding when starting with a high-torque load. The converter adapts to the load parameters, maintaining high precision of drive control.
• Frequency converters for pumps (smoke pumps) and fans have a system of protection and self-diagnosis, the functionality of the converters is thought out in order to meet the requirements of energy saving in various technological processes.
• They have increased resistance to dust due to a partially dust-proof metal housing, which extends the service life of the converter (from 11 to 200 kW). All electronic components are placed in a closed volume with a degree of protection IP40.
• They contain a highly efficient cooling system with a separate air duct, which ensures low overheating of the converter relative to the environment.
• They contain four programmable logic outputs (two relay and two types of "open collector"), it is possible to combine the functions of the outputs to create complex control dependencies, including cascade switching of pumps due to lack of pressure.
• Frequency converters for fans and pumps provide 24 control modes for the user to choose from: control panel, digital/analog inputs, PID controller, RS-485, etc.
• They allow you to adjust the motor voltage up to manual setting, it is possible to compensate for the reduced mains voltage.
• The motor is controlled by a specialized 32-bit Hitachi microprocessor using sinusoidal pulse-width modulation technologies, which allows to improve the current waveform and reduce harmonic distortion.
• Power circuits have low inductance and low active resistance, which allows you to increase efficiency.
• The control panel can be easily removed and removed from the case for user convenience.
• The control panel displays two different parameters simultaneously, including the physical magnitude of the signal of the connected sensor, the display of the remaining parameters is easily configured according to the user's needs.
• Frequency converters for fans and pumps with a power of up to 15 kW have a built-in brake interrupter.
• It is possible to control via the RS-485 digital serial interface with MODBUS protocol (as an option).
