Vector frequency converter 110 kW, 380V (SPLC-AT20-110G/132P4)

Three-phase frequency converters SPLC-AT20-110G/132P4 are powered by three-phase voltage 380 V and are designed to control three-phase asynchronous motors with a voltage of 380 V and a capacity of up to 110 kW.

The frequency converters of the SPLC-AT20-110G/132P4 series can switch to modes:

• Precise vector control with open loop (sensorless)
• Simple scalar control setting, involving regulation of voltage/frequency. This control is less precise but allows the "Pump" mode to work with motors of higher capacity — 132 kW.

Main parameters SPLC-AT20-110G/132P4:

• Maximum output frequency up to 600 Hz, resolution for digital frequency setting 0.01 Hz;
• Nominal power supply of the frequency converter — 3ph ~380V 50/60 Hz;
• Overload capacity: operating for 60 sec with an excess of nominal current up to 150%, for 3 sec — up to 180% (in “P” mode overload of 120% is allowed for 60 sec, 150% — no more than 3 sec);
• PID control with feedback;
• Internal controller (PLC);
• Remote control panel (LCD, indicators, configurable keys). By default, the removable operator panel is installed on the device, and for remote connection, it is necessary to order and purchase a connector separately (not included in the frequency converter price).

Main features SPLC-AT20-110G/132P4:

• It is possible to use the main and auxiliary frequency setting sources, their synthesis, switching between sources in different ways. Frequency settings can be made through:
  • Digital setting with keys on the operator panel in the corresponding menu item;
  • Digital setting using UP/DOWN terminals;
  • Digital setting via RS-485 port;
  • Potentiometer connected to the frequency converter;
  • Multistep speed with 16 preset rotation frequencies with a duration of up to 6500.0 hours, acceleration/deceleration time for each step;
  • PID control in a closed loop with switchable PID parameters;
  • Analog electrical signal;
  • High-speed pulse signal.
• Holding the start frequency up to 100.0 sec;
• Forced motor stop function by braking with DC;
• Choice of time and mode of acceleration/deceleration — linear or by S-curve;
• Sleep mode with activation periods to prevent water freezing;
• JOG mode;
• Protection features:
  • Password protection for menu access;
  • Motor and frequency converter overload protection;
  • Module overheating protection;
  • Phase failure detection at input/output;
  • RS-485 response timeout detection;
  • Overvoltage and undervoltage protection;
  • PID feedback sensor break detection;
  • Low and high water pressure alarm, motor stop on water shortage;
  • Display of 25 types of errors.
