Weakened magnetic field control scheme Integrated 4 kW DC controller 04KWDCEVIONE extends the compressor's operating range, increasing its versatility. MTPA current control scheme This 4 kW DC Integrated Controller makes maximum use of the compressor's characteristics, increasing energy efficiency. Triple-circuit control Closed-loop position, current and speed circuits ensure stable and reliable operation of the device, with high resistance to external influences. Reliable PFC scheme The software power factor correction technology ensures a low level of current ripple, with the power factor being above 0.99. PFC function:

• Extends the compressor operating range, maintaining operation over a wide voltage range (176–265V)

• Reduces harmonic distortions in the network

Soft start This 4 kW DC integrated controller ensures minimum current start-up, eliminating the strain on the electrical grid. Built-in protection

• Input and output current limitation for safe operation

• Module overheating protection

High efficiency Integrated 4 kW DC controller has an efficiency of over 95%, asigurând eficiență energetică și fiabilitate. Aceste tehnologii garantează stabilitate, durabilitate și eficiență energetică pentru soluții care respectă cele mai stricte cerințe pentru sisteme de control invertor.

Communication protocol

Standard Modbus Communication with the main controller is done via the standard Modbus protocol. Main transmission parameters:

• Against: RTU

• Date: 8 bits

• Bit the stop: 1

• Parity check: absent

• Check: CRC

• Transmission speed: 2400 baud (default)

• Hardware interface: RS485

Start and stop

• Starting: The axis activates upon receiving a non-zero command frequency.

• Stop: If the command frequency is zero, the axis stops.

Frequency adjustment

• Increasing the frequency: By default, growth is done at speed 1 Hz/sec or according to the parameter 40013.

• Frequency reduction: By default, the decrease is done at speed 1 Hz/sec or according to the parameter 40014.

Protection functions

Input current protection

Monitors the current to be below the maximum allowed value. If the current exceeds the limit for a 10 seconds, the controller issues an alarm signal and stops the axis.

Output current protection

Monitors the current to be below the maximum output value. If the current exceeds the limit for a 10 seconds, the axis stops with an alarm signal.

Overheating protection (IPM)

• At temperatures between 83–87°C, the speed of frequency increase is limited to 1 Hz/20 sec.

• At temperatures between 87–92°C, the frequency stabilizes.

• At temperatures between 92–99°C, the frequency decreases with speed 1 Hz/10 sec.

• At temperatures above 99°C, the device stops in 3 seconds.

• Normal operation returns once the temperature drops below 83°C.

Instantaneous Overload Protection (IPM)

When the set current or temperature threshold is exceeded, the IPM instantly disconnects to prevent damage to the IPM and demagnetize the compressor.

Surge protection

The system is protected against overload or voltage drop on the input and bus.

Emergency stop of the axis

1. If the compressor does not start, the system makes up to 6 attempts with interval of 10 secondsIf all else fails, the axis is forced to stop.

2. Integrated 4 kW DC controller also stops in case of overload or high pressure.

Phase loss protection

When detecting a lack of current in one of the phases, the compressor stops and emits an alarm signal.

Emergency stop in case of communication failure

If the controller does not receive data from the command device for 60 seconds, acesta emite un semnal de alarmă și se oprește până la restabilirea comunicației. Controler integrat 4 kW DC este destinat controlului pompei de căldură, perifericelor și compresorului cu putere termică de la 3.4 to 13 kW.

Benefits:

• Precise control of compressor rotation speed

• High energy efficiency thanks to inverter technology

• Long compressor life

• Silent and adaptive operation

• Support for variable operating modes (heating/cooling)

Recommended applications:

The 4 kW Dl integrated controller is ideal for HVAC systems, residential or industrial heat pumps, commercial air conditioning applications and energy-efficient refrigeration units.
