Unregulated Switching Power Supplies
The SPS series switch mode power supplies are specifically designed to power inductive loads found in stepping & servo motors. The normal regulated switching power supplies popular in the market are usually working with bad variability and low efficiency when used in stepping or servo driving, this is because that the conventional switching power supplies are designed for the constant and unvarying loads of circuit boards. Whereas, when the stepping or servo system running, the driving current varies extremely fast, which is belonged to inductive load, herein the drivers and power supplies would be damaged easily. This series supplies are capable of delivering current to drivers without affecting the reliability due to their unregulated specialty and bulky capacitance. By selecting correct model, one supply can supply 1-3 drivers and so the average cost of per shaft is saved
