Digital Soft Starters Supplier
A single phase soft starter for 1 phase compressors with up to 32 arms is called Digital Soft Starters. Narayani Electric Co is a wild range of Digital Soft Starters Supplier. Under balanced conditions, the Digital Soft Starters may restrict inrush currents to 45 AACrms and have a maximum ramp-up time of 600 ms. By allowing a maximum current of 80 AACrms, a special function (HP function) enables the RSBS to start compressors even when pressures are not balanced. The inbuilt electromechanical relay will bypass the semiconductors after the ramp-up. A provider of a sizable shipment of Digital Soft Starters is Narayani Electric Co. We offer these to our clients in standard forms; they are highly regarded in the industry for their accuracy. These are rigorously examined to maintain their highest quality.
Reduces complexity of installation and use
- Optimises the size of your enclosures (6 terminals instead of 12)
- Saves time during wiring
- Lowers the number of components to control (multifunction product)
- Minimises temperature rises (low heat dissipation)
Keeps your installations safe
Reduces mechanical pressures on the machines, lengthens the life of your installations, and prevents installation failure by spotting and alerting defects like a blocked motor, an overloaded system, or improper earthing of one of the three phases.
A safe product with numerous integrated functions
- Bypass and safety functions
- Protection devices for monitoring the motor, the electrical installation and the starter itself
- Simple setup and operation with:
– 4 light emitting diodes (LEDs)
– 4 navigation keys
– 4-digit display
– SoMove setup software (common to the Altivar, Lexium and TeSys ranges) - Coated cards as standard for enhanced resistance to harsh environments

We recommend the use of :
- Line Contactor : This will isolate and protect the soft starter SCR’s from any voltage transient while it’s not in
- Semiconductor fuses : This will protect the starter SCR’s during starting and stopping states from current transient’s and excess I²
