Softstart UK is proud to introduce its new range of LV-AS Analog soft starters now in an IP65 Enclosure.

Features at a glance

• 18 A ~ 200 A (7.5 ~ 110 kW @400 VAC)
• Soft start/stop + essential motor and system protection
• Compact and cost-effective
• Easy to configure
• Current rises from a specified starting level to a maximum limit, over an extended period of time.
• Eight adjustments can be made on the LV-AS soft starters:
– Current Limit
– Current Ramp
– Stop Ramp Time
– Motor FLC
– Motor Trip Class
– Excess Start Time
– Phase Sequence Protection
– Auxiliary Relay Function

Current Ramp

• Useful for applications where:
– the load can vary between starts
– the load breaks away easily, but starting time needs to be extended
– the electricity supply is limited (eg generator sets)

Protection

• Motor Overload (thermal model)
• Excess Start Time
• Bypass Relay Overload
– bypass relay temperature
– 600% FLC
• Motor Thermistor (built-in thermistor input)
• Power Circuit Fault (mains supply, motor circuit, starter SCRs)
• Phase Imbalance
• Supply Frequency (<40Hz and >72Hz)
• Phase Sequence
• Communication Failure (between communication module and starter or network)
• Compared with other two phase starters:
– More starts per hour
– Heavier duty loads
– Larger motors
