Vector frequency converter 160 kW, 380 V (SPLC-AT20-160G/185P4)

Three-phase frequency converters SPLC-AT20-160G/185P4 are powered by three-phase voltage 380V and are designed for controlling three-phase asynchronous motors with a voltage of 380V and power of up to 160 kW.

The frequency converters model series SPLC-AT20-160G/185P4 can switch to modes:

• Precise vector control with open loop (sensorless)
• Simple scalar control settings, consisting of voltage/frequency adjustment. It's less precise but allows "Pump" mode operation with more powerful motors — 185 kW.

Main parameters SPLC-AT20-160G/185P4:

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

Main capabilities SPLC-AT20-160G/185P4:

• Ability to use main and auxiliary frequency reference sources, their synthesis, switching between sources in various ways. Frequency settings possible through:
  • Digital panel operator key settings in the menu;
  • Digital setting via UP/DOWN terminals;
  • Digital setting through RS-485 port;
  • Potentiometer connected to the frequency converter;
  • Multi-step speed with 16 frequency presets with duration up to 6500.0 hours, acceleration/deceleration time for each step;
  • Closed-loop PID control with switchable PID parameters;
  • Analog electrical signal;
  • High-speed pulse signal.
• Holding start frequency up to 100.0 s;
• Forced stop function with DC braking;
• Choice of acceleration/deceleration time and mode — linear or S-curve;
• Sleep mode with on-periods to prevent water freezing;
• “Jog” mode;
• Protection functions:
  • Menu access protection with password;
  • Motor and frequency converter overload protection;
  • Module overheating protection;
  • Phase failure detection at input/output;
  • Response time exceeded detection for RS-485;
  • Overvoltage and undervoltage protection;
  • Feedback sensor failure detection for PID control;
  • Low and high water pressure alerts, motor stop in case of water shortage;
  • Display of 25 error types on the screen.
