Softstarter for heat pump ACS-R90KM6–40A

Softstarter for heat pump ACS-R90KM6–40A

ACS-R90KM6–40A is designed for controlled starting of single-phase compressors used in heat pumps, thermodynamic boilers, chillers and HVAC systems. The device reduces starting current and minimizes electrical and mechanical shocks to the compressor.

By using a heat pump softstarter, the ACS-R90KM6–40A Softstarter operates more stably, wear on electrical components is reduced, and the service life of the equipment is considerably increased.

Technical features

• Soft start for single-phase 220V compressors
• Starting current reduction by up to 70%
• Compatible with 4HP and 5HP heat pumps
• Electrical overload protection
• Contactor bypass integrat
• Automatic restart protection
• Compact and durable housing
• Quick installation in HVAC and refrigeration systems

Benefits of use

• Reduction of current peaks when starting the compressor
• Protecting the electrical grid and generator
• Reducing vibrations and mechanical shocks
• More stable heat pump operation
• Increasing compressor life
• Reducing the risk of voltage drop

Where to use

The ACS-R90KM6–40A heat pump soft starter can be used in:

• air-to-water heat pumps;
• heat pump boilers;
• compact chiller;
• residential HVAC systems;
• single-phase air conditioners;
• refrigeration equipment.

Operating principle

When a compressor starts, the current drawn can exceed several times the rated value. The ACS-R90KM6–40A heat pump soft starter controls the voltage applied to the motor during start-up and reduces the strain on the electrical installation.

This technology allows for smoother compressor start-up, eliminates electrical shocks, and contributes to the safe operation of HVAC equipment.

Protection and reliability

• Electronic overload protection
• High dielectric strength
• Anti-vibration protection
• Restart protection – 180 seconds
• Flameproof housing with epoxy sealing
• Temperature resistance between -40°C and +85°C

Construction specifications

• Dimensions: 120 × 70 × 40 mm
• Weight: approximately 200g
• Working humidity: 0–95% RH
• Simple and compact installation

The ACS-R90KM6–40A heat pump soft starter is an effective solution for protecting compressors and optimizing the operation of HVAC and refrigeration systems.
