Overvoltage Protection
The PWR-24V48VCLAMP is an active crowbar circuit clamp that can be placed in parallel with
the supply and driver. Motors that are a perfect 1:1 ratio with a large inertial load are expensive
and unnecessary because the motor may not be used to its fullest torque potential. Using smaller
motors may result in high inertia mismatch and do not accommodate for the large inertial load
when applying torque or slowing the motor down, causing voltage to travel to the power supply
and risking damage to sensitive components. When active, the PWR-24V48VCLAMP returns the
voltage input to the preset voltage level, only dissipating power when the clamp has been triggered
by excess voltage. Depending on the 24VDC and 48VDC input setup, the clamp limits the voltage
supply to 27 volts and 54 volts respectively when there is excess voltage. With a compact size of
4.25 in x 2.25 in x 0.82 in mounted on an L Bracket, the PWR-24V48VCLAMP can be mounted just
about anywhere.
