650MA SSD Series Soft Shift Controller

Power Input, 650mA Output, DIN 43650 

The Soft Shift Controller introduces a current ramp permitting the soft start of proportional solenoid valves used for pressure or flow control in hydraulic circuits. When the unit is powered on, it ramps to full current output over the ramp on time period that is adjustable within a factory set range. When the power is switched off, output of the unit falls immediately to zero. It is available in an IP65 rated DIN 43650 coil mount version.


  • Cost effective alternative for soft start of proportional hydraulic circuits
