Three phase AC motor soft starter
Benets
• 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 - 45 Arms in 45 mm wide
housing, 55 - 100 Arms in 75 mm 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 100 Arms.
The starting parameters can be easily set-up
through 3 selector switches.
The integrated motor overload protection (Class
10)* and Modbus communication** result in a
higher installation exibility.
Applications
RSGD soft starters are the ideal solution for 3-phase xed 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 oers a number of integrated diagnostic functions that can replace additional components inside
the electrical panel.
Typical applications include: compressors, pumps and fans.
