The ultimate generation of low-voltage soft starters for three-phase asynchronous motors

Models fitting any connection requirements:
ASA 4.0 BASIC Two-phase soft starter with integrated bypass connector for in-line connection to the motor
ASA 4.0 ADVANCED Three-phase soft starter with integrated bypass connector for in-line connection or inside delta connection to the motor

Static soft starters ASA 4.0 by Santerno ensure reliable control of the soft start and stop of three-phase motors. A product designed to meet our Clients’ requirements in a simple and user-friendly manner: enhanced display functions, advanced connectivity and easy data access.

Mains power supply:
200 Vac to 525 Vac
380 Vac to 600 Vac (ASA 4.0 BASIC)
380 Vac to 690 Vac (ASA 4.0 ADVANCED)

Control circuit power supply:
110 to 120 Vac (+10%/-15%)
220 to 240 Vac (+10%/-15%)
24 Vac/dc (±20%)

– Overload up to 600% of the rated current
– From 24 A to 580 A
– Integrated bypass contactor
– Multilanguage graphic display with quick configuration menu for the most common applications
– The integrated USB port allows storing performance data, updating the firmware and configuring the device easily and quickly, thus reducing to a minimum the inactive periods of the plant
– The whole soft starter range, from 24A to 580A, comes with two sizes that are up to 30% more compact if compared to other devices of the same class
– An exclusive function of the ASA 4.0 is the management of the QR codes generated by the display. Scanning the QR code from your smartphone or tablet allows easy access to device information or trip messages
– Certification: CE, UL, RCM and Lloyd’s Register
– Compatible with the “REMOTE DRIVE” software for the remote control of the device

– The integrated planning and automation functionality enables programming and executing custom operations to meet different plant requirements while reducing manual control to a minimum and ensuring continuous operation

– Uncontrolled phase balance. The BASIC model controls two phases; however, the uncontrolled phase balance allows balancing the output waveform to make it symmetric, offering the same performance and benefits as three-phase control, namely lower temperature and lower motor inrush current

– Wide range of configurable protection features: Overcurrent, Undercurrent, Current Imbalance, Motor Thermistor, Phase Sequence, Phase Loss, Power Loss

– Run Simulation: allows testing the soft starter operation when disconnected from mains voltage by simulating the connected motor operation and viewing the states of the analog and digital inputs/outputs

– Advanced functions: Fire Mode, Constant Current and Current Ramp Starting, Adaptive Control Start/Stop, Coast to Stop and TVR

– Available motor configurations: 1

– Number of controlled phases: 2
