A compact and cost-effective soft starter
An extremely cost-effective and compact soft starter that provides basic soft start and stop functionality and easy DIN rail mounting.
The ‘fit and forget’ semiconductor design simplifies installation and reduces required panel space, and selection can be made on the basis of the motor power. Timed voltage ramp up and down are possible. Ramp time can be individually and accurately adjusted with rotary switches from 0.4–10 seconds, and starting torque can be adjusted from 0–85% of the direct on-line torque.
Supply voltages and power range
- 3 x 208-600 V...0.1-11 kW (25 A)
- 24-480 V AC or DC
Features and benefits
Panel space can be saved due to the compact size
Selection is simple and stock is kept to a minimum thanks to universal control voltage
Commissioning time and space are saved as a result of easy DIN rail mounting for sizes up to 30 kW
Reliable operation is ensured due to robust semiconductor design and an almost unlimited number of starts per hour without derating
No external cooling or oversizing is necessary thanks to the maximum ambient temperature of 50°C without derating
Scroll compressors or reciprocating compressors in air-conditioning units, conveyors, pumps, fans and mixers.
Drives for compressors in residential buildings
Variable speed control of a chiller allows you to provide constant pressure regulation while matching the capacity to the actual need based on measurements in the system. Speed control is beneficial when a compressor runs for long periods at partial load. Reduce operational costs by running applications at a lower speed which reduces energy consumption. And reduce installation costs by optimizing the system and the compressor itself.
