Over current protection: when the output current is higher than the set value, the output voltage gradually decreases until there is no output voltage.
Over temperature protection: When the case temperature is 85 the power converter stops working, and there is no voltage output.
Low voltage protection: When the input voltage is lower than the set value, the output voltage gradually decreases until there is no output voltage.

SK13530 programmable power supply is a new generation of programmable DC power supplies. It protects itself by warning and cutting off output once fun controlling module gets fault, transistor over-heating, and internal bus gets fault. It is of programmable CV/ CC adjustable step.
Brief Introduction
Programmable DC Power Supplies SK13530 programmable power supply is a new generation of programmable DC power supplies. It protects itself by warning and cutting off output once fun controlling module gets fault, transistor over-heating, and internal bus gets fault. It is of programmable CV/ CC adjustable step. The two working states, CV and CC, can be switched varying with the load. Meantime, the external voltage sampling terminal is supplied to output stable voltage for user load within the range of wire voltage drop.
SK13530 programmable power supplies are widely applied in national defense, institution, university and factory, especially in the areas of computer measuring and automatic control system as DC power supply.
