Three-phase frequency converters SPLC-AT20-132G/160P4 are powered by three-phase voltage 380V and designed for controlling three-phase asynchronous motors with voltage 380V and power up to 132 kW.
The model of frequency converters series SPLC-AT20-132G/160P4 can switch to modes:
- Precise vector control with open loop (sensorless)
- Simple scalar control, which involves adjusting voltage/frequency. This control is less precise but allows enabling "Pump" mode to work with higher power motors — 160 kW.
Key Parameters of SPLC-AT20-132G/160P4:
- Maximum output frequency up to 600 Hz, resolution for digital frequency setting 0.01 Hz;
- Rated power supply of frequency converter — 3ph ~380V 50/60 Hz;
- Overload capability: operation for 60 s with exceeding rated current up to 150%, for 3 s — up to 180% (in “P” mode overload of 120% is permissible for 60 s, 150% — no more than 3 s);
- PID control with feedback;
- Internal controller (PLC);
- Remote control panel (LCD display, indicators, configurable keys). By default, the detachable operator panel is installed on the device, for remote connection it is necessary to additionally order and purchase a connector (not included in the cost of the frequency converter).
Main Features SPLC-AT20-132G/160P4:
- It is possible to use the main and auxiliary source of set frequency, their synthesis, and switch between sources in various ways. Frequency settings are possible through:
- Digital setting with keys on the operator panel in the relevant menu item;
- Digital setting via UP/DOWN terminals;
- Digital setting through RS-485 port;
- Potentiometer connected to the frequency converter;
- Multi-step speed with 16 preset rotation frequency settings with duration up to 6500.0 hours, acceleration/deceleration time for each step;
- PID control in closed loop with switchable PID parameters;
- Analogue electrical signal;
- High-speed pulse signal.
- Hold start frequency up to 100.0 s;
- Forced motor stop function with DC braking;
- Choice of acceleration/deceleration time and mode — linear or S-curve;
- Sleep mode with periods of activation to prevent water freezing;
- “JOG” mode for fine positioning;
- Protection functions:
- Menu access protection with password;
- Protection of motor, frequency converter from overload;
- Module overheating protection;
- Detection of input/output phase break;
- Detection of response timeout for RS-485;
- Overvoltage and undervoltage protection;
- Detection of feedback sensor break for PID;
- Low and high water pressure alarm, stopping motor when no water;
- Display of 25 types of errors on the screen.
