Sprint Electric has increased its range of digital DC drives up to 1050A for applications in the steel, plastics, rubber, and paper industries.
PLA module replaces PLC or PC based systems
A 'stand alone' PLA module with extended functionalities can compliment and enhance any analogue or digital drives system and reduce or eliminate the need for PLC or PC based systems.
Easy to access adjustments and plug on screw terminals make these units quick to install and run.
Dual voltage supply and selectable AVF or tacho feedback are included in the standard features.
The range comprises of three types: non-isolated, isolated 1 quadrant, and isolated regenerative four quadrant DC drives.

Regenerative four quadrant DC drives save energy
Compact regenerative four quadrant DC drives are designed to regenerate energy under braking without using complex intermediate storage, resistive dumping or additional power bridges.
Power ratings range from 0.55kW to 1.8kW at 180V DC, 1/2 to 2HP, with current capability of 3.4A, 6.8A, and 12.2A respectively.
The non-isolated 340, 680 and 1220 models offer basic functionality at a very competitive price.
With a footprint starting at just 35mm x 105mm, they fit easily into existing control panels or save space in new designs.
The isolated drives of the 340i, 680i and 1220i series offer a solution to one quadrant drive applications where connection to other drives or ancillary equipment is required.
The fully isolated models 340XRi, 680XRi and 1220XRi are designed for four quadrant regenerative drive applications where fast controlled deceleration / stopping or the control of overhauling loads are required.
The XRi drives are able to regenerate energy back into the mains supply under braking without the need for complex intermediate storage, resistive dumping or additional power bridges.
With four quadrant operation, the torque can be reversed very gently or almost instantly, as required.
The motor controllers are part of an integrated range of analog or digital products, available from 0.37kW to 265kW.
