COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Bus Converter . Power Module TypeInstruction Manual1.5 Heatsink!The power supply adopts the conduction cooling system. Attach aheatsink to the aluminum base plate to cool the power supply foruse.Refer to“Derating”.2 Function2.1 Overcurrent protection!The overcurrent protection circuit is not built-in.2.2 Overvoltage protection!The overvoltage protection circuit is built-in. The AC input shouldbe shut down if overvoltage protection is in operation.When this function operates, the power factor corrector functiondoes not operate, and output voltage becomes the full-wave rectified AC input voltage.Remarks:Please note that the unit’s internal components may be damagedif excessive voltage (over rated voltage) is applied to output terminalof power supply. This could happen when the customer teststhe overvoltage performance of the unit.2.3 Thermal protection!Thermal protection circuit is built-in and it operates about 115C.If this function comes into effect, shut down the output, eliminateall possible causes of overheating, and drop the temperature tonormal level. To prevent the unit from overheating, avoid using theunit in a dusty, poorly ventilated environment.When this function operates, the power factor corrector functiondoes not operate, and output voltage becomes the full-wave rectified AC input voltage and ENA output changes into "H".2.4 Auxiliary power supply circuit for externalsignal (AUX)!Shortprotection resistance (2.2kW) is built in.Output voltage decreases as the output current increases.!Never let a short circuit occur between the AUX pin and otherpins. It may damage the unit.12V2.2kWAUX2.5 Enable signal (ENA)!Use ENA to control starting of the loaded power supply.!When inrush current protection circuit is released, ENA outputs“LOW”.!If load current flows without releasing of the circuit, the resistormay be burnt.Table 2.1 Specifi cation of TMP, IOGNo.ItemENA1FunctionOutput passible "L"Output prohibited "H"2Base pin-VOUT3Level voltage "L"0.6V max at 10mA4Level voltage "H"Open drain5Maxmum sink current10mA max6Maxmum applied voltage35V max2.6 Isolation!For a receiving inspection, such as Hi-Pot test, gradually increase(decrease) the voltage for a start (shut down). Avoid using Hi-Pottester with the timer because it may generate voltage a few timeshigher than the applied voltage, at ON/OFF of a timer.3 Series and ParallelOperation3.1 Series operation!As input and output are not insulated, series operation is impossible3.2 Parallel operation!Parallel operation is not possible.4 Cleaning!Clean the product with a brush. Prevent liquid from getting into theproduct.Do not soak the product into liquid.!Do not stick solvent to a name plate or a resin case.(If solvent sticks to a name plate or a resin case, it will causeto change the color of the case or to fade letters on name plateaway.)!After cleaning, dry them enough.-VOUTFig.2.1 AUX circuitDPG-9
