S801+ Soft Starter

24 Vdc Control Power Requirements
The S801+ Soft Starter requires 24 Vdc control power. The
sealed in and inrush characteristics of the S801+ Soft Starter
are summarized in the table below:
Control Power Requirements
For applications where one starter is used with one power
supply, the power supply selected must be equal to or
greater than both the sealed in and inrush requirements of
the starters.
●
Max Steady State for the power supply ≥ Sealed In Power
of the Starter
●
Outrush for the power supply ≥ Inrush Power of the Starter
Multiple starters can be used with one power supply. If the
application requires the starters to start at the same time, the
power supply must be sized for the sum of the sealed in and
inrush power for each starter.
●
Max Steady State for the power supply ≥ Sum of the
Sealed In Power of all the Starters
●
Outrush for the power supply ≥ Sum of the Inrush Power
of all the Starters
Formulas to calculate control power requirements are as
follows:
●
Definitions:
SI = Sum of Seal Incurrent
LS = Largest Seal Incurrent
LI = Largest Inrush Needed
TS = Total Seal Incurrent Needed
LO = Largest Outrush Needed
●
TS = (SI –LS)
LO = TS +LI
●
Max Steady State for the power supply ≥ SI
●
Outrush for the power supply ≥ LO
The voltage on the S801+ Control Power Supply and Control
Input terminals must be 24 Vdc ±10% to provide proper
operation of the soft starter.
