Featuring high-precision CC/CV output, a 2.8-inch IPS display, programmable presets, PC software support, firmware upgrades, and eight comprehensive protection mechanisms, the DPS-150 offers professional-grade performance in a portable form factor.FNIRSI® DPS-150 Mini DC Adjustable CNC Switching Power Supply Datasheet⚠ PrecautionsThe product operates in step-down mode, so ensure that the input voltage is higher than the output voltageThe power supply range for this product is Dc 5V~30v. Output will be disabled if the input voltage is lower than 5.0V due to undervoltage lockout, and the device may be damaged if the input voltage exceeds 30V. lt is recommended to use a power supply ranging from 5V to 30V.When supplying power to inductive and capacitive loads, it is recommended to connect the load before turning on the device output.When outputting high power, some heat generation is normal. lt is recommended to use the device in a well-ventilated environment.Please remember not to connect power to both power ports of the device simultaneously, as simultaneous power supply may potentially damage the input source with lower voltage.When charging batteries, it is strongly recommended to add a reverse current protection module (such as a Schottky diode) to the output end to protect the device from damage.Features:0–30V Adjustable Output Voltage0–5A Adjustable Output Current150W Maximum Output PowerConstant Voltage (CV) & Constant Current (CC) ModesHigh Precision Output (0.01V / 0.001A Resolution)Supports USB Type-C PD Fast Charging InputSupports QC Fast Charging InputSupports DC Adapter & Power Bank Input2.8-inch IPS Color Display90° Auto-Rotating Display6 Programmable Voltage & Current PresetsReal-Time Numerical & Curve DisplayPC Software SupportFirmware Upgrade SupportLow Ripple Output (<20mV)Compatible with Banana Plugs, U-Terminals & Copper WireCompact & Portable DesignBasic SpecificationsParameterValueBrandFNIRSI®ModelDPS-150Product TypeProgrammable DC Switching Power SupplyDisplay2.8-inch IPS Color ScreenDisplay Resolution320 × 240 PixelsWeightApprox. 178gDimensions106 × 76 × 28mm Input SpecificationsParameterValueInput VoltageDC 5V – 32VInput Current100mA – 5AInput MethodsUSB Type-C PDQC Fast ChargerDC Power AdapterPower Bank Output SpecificationsParameterValueOutput Voltage0 – 30V DCOutput Current0 – 5AMaximum Output Power150WOutput ModeConstant Voltage (CV) / Constant Current (CC)Voltage Resolution0.01VCurrent Resolution0.001AOutput Ripple<20mVLoad Regulation0.49%Full Load Efficiency96.30% Display & User InterfaceParameterValueDisplay Size2.8 InchesDisplay TypeIPS Color LCDScreen Resolution320 × 240 PixelsScreen Rotation90° Auto RotationDisplay ModeNumerical & Graphical CurveVoltage & Current Presets6 GroupsReal-Time MonitoringSupported Protection FeaturesProtectionSupportOver Voltage Protection (OVP)YesOver Current Protection (OCP)YesUnder Voltage Protection (UVP)YesOver Power Protection (OPP)YesOver Temperature Protection (OTP)YesReverse Input ProtectionYesReverse Output ProtectionYesShort Circuit Protection (SCP)Yes Connectivity & SoftwareParameterValuePC SoftwareSupportedFirmware UpgradeSupportedOutput Connectors4mm Banana PlugU-Type TerminalCopper Wire Performance SpecificationsParameterValueOperating Temperature0°C – 40°CWorking ModeStep-Down (Buck Converter)Recommended Input Voltage5V – 30V DCHigh Power CoolingPassive Heat Dissipation Important PrecautionsPrecautionDescriptionInput VoltageInput voltage must always be higher than the desired output voltage.Maximum InputDo not exceed 30V DC input.Minimum InputOutput is disabled below 5V due to undervoltage protection.Inductive/Capacitive LoadsConnect the load before enabling the output.Battery ChargingUse a reverse current protection module (Schottky diode recommended).CoolingEnsure adequate ventilation during high-power operation.Dual Power InputDo not connect two input power sources simultaneously.
