Advantages / Customer benefit
• For starting current limitation in heat pumps to provide
stable mains conditions
• Only one small device 67.5 mm for
softstart, motor protection, voltage- and phase sequence monitoring
• Soft start and minimized staring current
• Extended service life of AC - motors and mechanical drive system
• Motor power up to 18,5 kW
• Short ramp up time: < 200 ms
• Energy saving by bridging of the semiconductors after softstart
• Symmetrical staring current
