P1-02520-HFUF

The new SJ-P1 can easily handle heavy loads that require high starting torque at low speed.  This series is also great for high speed rotation applications because of a 590Hz maximum operating frequency.

• VLD = very light load (110% 60 seconds, 120% 3 seconds)
• LD = light load (120% 60 seconds, 150% 3 seconds)
• ND = normal load (150% 60 seconds, 200% 3 seconds)

The built-in automatic speed adjustment reduces the risk of issues with trips during acceleration and deceleration. You can control both induction and permanent magnet motors and there are easily accessible slide-in cassettes to enhance integration and performance.

The SJ-P1 variable frequency drives are ideal for fans, pumps, hydraulic pumps, cranes, lifts, injection molding machines, milling machines and winders.

January 2018: The SJ-P1 has replaced the SJ700D series.
