Frequency drive ZN2400-15G / 18.5P (NIETZ) Power - 15 kW for general industrial use, 18.5 kW for pumps and fans.

Power - 3-f 380 V Vector algorithm without feedback (sensorless) Overload - 150% (1 min)

Vector frequency converter. Management is implemented on a specialized DSP-processor Texas Instruments. 
Operating modes: 
- scalar (V / F); 
- Vector without feedback (sensorless).

The output frequency is 0-320 Hz in vector mode; 0-3200Hz in scalar mode 
Automatic slip compensation mode; 
Improved support for increased torque at low rpm: 
- 0.5 Hz, 150% (vector mode without feedback);

Protection against: 
- increased and reduced voltage; 
- current overload protection (150% - 1 min, 180% - 3 sec); 
- overheating of IGBT-transistors; 
- transition to the stop mode when an external logical alarm signal is applied;

Direction and speed control: 
- potentiometer on the keyboard; 
- external discrete signals to the drive terminal block; 
- external analog signals (0-10 V, 0-20 mA); 
- via the MODBUS network (RS-485);

Printed circuit boards are covered with acrylic lacquer.

Operating temperature range - -10 ... + 40 gr. Tselcia

Allows fourteen preset frequency settings, which can be triggered sequentially or selected by discrete signals.
