Scalar frequency converter 0.4 kW, 3F~3F/380V (SPLC-NLP1000-0R4G4)

Delivery Set

• Scalar frequency converter series SPLC-NLP1000-0R4G4

Additional Information

Power Circuit of Frequency Converters SPLC-NLP1000-0R4G4:

• Power supply from a three-phase grid 3ph 380 V AC 50/60 Hz;
• The linear output voltage ranges from 0 to 380 V, and frequency — in range from 0.1 to 400 Hz;
• Permissible overload for 60 s — up to 150% of the nominal current (in continuous operation mode)

Control Circuit SPLC-NLP1000-0R4G4:

• 4DI — four digital inputs, functions can be independently assigned through menu selection. For instance, a digital input can be used for start command, forward run, reverse, stop, JOG frequency skip, switching between frequency sources X and Y, switching between 16 preset speed frequencies, switching between 4 acceleration and deceleration modes, remote frequency increase/decrease, timer start-up, PID control activation, built-in controller program, etc.
• 1AI — one input that can be switched via jumper J2 to accept the appropriate analogue signal by current 4...20 mA or voltage 0...10 V for frequency setting;
• 1DO — one multifunctional digital output (relay) which can be used for ON-OFF output signal about operational status, achievement of frequency or time counter, step or program cycle completion;
• RS485 — RS485 serial port connector for integration into an industrial set of NL frequency converters, controllers, industrial PCs, etc.

How to Choose the Right Model of Scalar Three-phase Frequency Converter Series SPLC-NLP1000 380V?

Since the output voltage of SPLC-NLP1000-0R4G4 is 380 V, three-phase motors 220/380 V need to be connected using a "star" winding connection scheme. Corresponding motor parameters for these connections are indicated on its nameplate. Choose the frequency converter model so that the nominal current and power listed are greater than those of the motor.
