Soft Starter Introduction
The Delixi Soft Starter is a motor control equipment featuring soft start, soft parking, light-loading and energy-saving as well as multi-functional protection. The soft starter enables smooth and impact-less start during the whole start process, and the parameters such as current limit and start time can be adjusted according to the characteristics of the motor load. It can be divided into two categories: the Device-type Soft Starter and the Comprehensive-protection Soft Starter.
Applications
The soft starter can be applied to motors in crushers, compressors, transmission, pumps and air blowers
Product Characteristics
1. A Variety of Start Modes: Current limit soft start, ramp voltage soft start, ramp
voltage + current limit soft start.
2. Highly Reliable: A high-performance microprocessor performs digital processing
of the signals in the control system.
3. Strong Anti-interference Capability: Easy-tuning, optoelectronic-isolato r-based
signal transmission in the processing unit, di fferent anti-noise levels.
4. Optimum Structure: Unique compact structure, double-layer shell consisting of
plastic upper layer and metal lower layer to meet the aesthetic and durability
requirements.
5. Motor Protection: Multi-functional protection (e.g. in case of over-current,
input/output default phase, SCR short-circuit and overheat).
6. Easy Maintenance: Four-digit signal monitoring system to monitor the operation
of the system equipments in 24 hours and to offer quick fault diagnosis.
