S4 Series
NEMA 4X Washdown Drives
|
The Benshaw S4 Series is a line of high performance NEMA 4X
washdown variable frequency drives.
S4 Series drives are built to withstand harsh environments and
hold up under demanding pressure washing
applications.
All S4 Series drives combine a simple user
interface with an array of features, including more than 180
configurable parameters to match specific application and
interface requirements. A standard dynamic braking transistor
and resistor are also included for regenerative applications.

|
Benshaw SG Series drives are high performance industrial
drives designed for the most demanding applications. The SG
Series' flexible power stack allows the user to apply it to
heavy duty loads (150% for 60 seconds), standard duty loads
(120% for 60 seconds) or variable torque loads (110% for 60
seconds).
Key Advantages:
-
Standard and heavy duty ratings
-
Integral PID control
-
Sensorless vector control or V/Hz control
-
Integral multiple motor control for pumping applications
-
Uploadable/downloadable keypad
-
Flexible, programmable I/O
-
Economical, compact design
-
Simple, easy-to-use LCD interface
-
Standard Modbus port
-
Windows-based software
With more than 250
programmable parameters, Benshaw SG Series drives can be
configured to meet the needs of almost any industrial
application, yet they remain simple and easy to use.

Standard and Heavy
Duty Ratings
The user can choose from two power ratings to
match the specific application requirements. The SG Series
Standard Duty rating provides the user with a reliable solution
for applications requiring overload protection of 120% for 60
seconds. The heavy duty rating provides the user with a robust
power section for loads requiring high starting torque and
higher peak overloads of 150% for 60 secs.
