SM 3000 with Power Sink Option
2 Quadrant operation: Source and Sink
SM45-70D with Power Sink Op tion
Cur rent –10 A means the load de liv ers 10 A to
the power sup ply (sink op er a tion)
Up per trace: out put volt age
Lower trace: out put cur rent
(cur rent switch ing from +40 A to –10 A at Vo=15 V)
SM45-70D with out Power Sink Op tion
The out put volt age is out of con trol when
the out put cur rent is neg a tive
Up per trace: out put volt age
Lower trace: out put cur rent
(cur rent switch ing from +40 A to –10 A at Vo=15 V)
The Power Sink option permits the power supply to absorb
bursts of power fed back to the unit. An internal module senses
the status of power supply and sinks current across the output
terminals, thus maintaining a constant output voltage.
The Power Sink Option allows a faster response when the
power supply is step programmed to a lower voltage at small
load conditions.
• Can absorb 300 W peak power
• Maintains output voltage setting regardless output power
is positive or negative (source and sink)
• Ideal solution for supplying electric motors with
PWM-speed control. These systems often return power to
the power supply during a braking action
• Ideal solution for ATE systems requiring fast down
programming at no load conditions
• Generation Automotive waveforms (fast)
