Vector frequency converter 185 kW, 380V (SPLC-AT20-185G/220P4)

Three-phase frequency converters SPLC-AT20-185G/220P4 are powered by a three-phase voltage of 380 V and are designed for controlling three-phase asynchronous motors with a voltage of 380 V up to a power of 185 kW.

The frequency converter model series SPLC-AT20-185G/220P4 can switch to the modes:

• Precise open-loop vector control (sensorless)
• Easy-to-set scalar control, which involves adjusting the voltage/frequency. This control is less accurate but allows you to enable the "Pump" mode to work with motors of higher power — 220 kW.

Main parameters of SPLC-AT20-185G/220P4:

• Maximum output frequency up to 600 Hz, resolution for digital frequency setting 0.01 Hz;
• Rated power supply of the frequency converter — 3ph ~380V 50/60 Hz;
• Overload capacity: operation for 60 s with exceeding rated current up to 150%, for 3 s — up to 180% (in "P" mode, overload 120% for 60 s, 150% — no more than 3 s is allowed);
• PID control with feedback;
• Internal controller (PLC);
• Remote control panel (liquid crystal display, indicators, customisable keys). By default, the removable operator panel is installed on the device, and for remote connection, you need to additionally order and purchase a connector (not included in the cost of the frequency converter).

Main capabilities of SPLC-AT20-185G/220P4:

• Can use main and auxiliary frequency set sources, synthesize them, switch between sources in different ways. Possible frequency settings via:
  • Digital setting with keys on the operator panel in the corresponding menu section;
  • Digital setting using UP/DOWN terminals;
  • Digital setting via RS-485 port;
  • Potentiometer connected to the frequency converter;
  • Multistep speed with 16 frequency rotation presets with a duration of up to 6500.0 hrs, acceleration/deceleration time of each step;
  • PID control in a closed loop, with switchable PID parameters;
  • Analogue electric signal;
  • High-speed pulse signal.
• Holding the start frequency up to 100.0 s;
• Function for forced stopping of the motor by braking with direct current;
• Selection of time and mode of acceleration/braking — linear or following S-curve;
• Sleep mode with activation periods to prevent water freezing;
• "JOG" jog mode;
• Protection functions:
  • Password menu access protection;
  • Protection of the motor, frequency converter against overload;
  • Module overheating protection;
  • Phase break detection at input/output;
  • Response time exceeded detection via RS-485;
  • Overvoltage and undervoltage protection;
  • Feedback PID sensor failure detection;
  • Alarm for low and high water pressure, motor stop when water is insufficient;
  • Displaying 25 types of errors on the display.
