RSGD
Three phase AC motor soft starter
Benefits
•
Easy to use.
The RSGD is equipped with a self-learning
algorithm that automatically adjusts the start parameters
to optimise the motor starts and stops.
•
Fast installation and set-up.
Only 3 settings are
required (FLC, ramp-up and ramp-down).
•
Compact dimensions.
12 - 45Arms in 45mm wide
housing, 55 - 100Arms in 75mm wide housing.
•
Integrated protection.
Diagnostic functions provide
additional protection. RSGD is also equipped with an
overload protection (Class 10)*.
•
Torque control during ramp-down.
Smoother
deceleration of the load.
•
Complete monitoring.
The RSGD is equipped with
a Modbus/RTU communication port by 2-wire RS485
connection**.
•
Guided model selection.
Easy to use selection tool to
select the appropriate soft starter model depending on
the application type.
Description
RSGD is an extremely compact and easy to use
3-phase soft starter for AC induction motors rated
up to 100Arms.
The starting parameters can be easily set-up
through 3 knobs.
The integrated motor overload protection (Class
10) and Modbus communication** result in a
higher installation flexibility.
Applications
RSGD soft starters are the ideal solution for 3-phase fixed speed AC induction motor applications where there
is the need to reduce the starting current and/or minimise stresses on the motor during start and stop.
The RSGD offers a number of integrated diagnostic functions that can replace additional components inside
the electrical panel.
Typical applications include: compressors, pumps and fans.
Main functions
•
Soft starting and soft stopping of AC motors.
•
Integrated electronic overload protection (Class 10)*.
•
Serial communication (Modbus) over RS485**.
* RSGD VD210, VX210, VX310C, VX311C models only
** RSGD 75mm models only

Note: when using the RSGD on high inertia loads (Trip Class 20, 30) ensure that enough time is left between
starts to allow the RSGD to cool down.
* For RSGD 45mm models set ramp-up time to 20.
