Product Description Single DC Power Supply which output ultimate power is less than 100W and current is less than 10A.Output Fu Ground Voltage: Leading-out terminal and the chassis ground is Voltage suspensionOutput voltage and current can be preset: The output voltage and current can be preset in advance, so as to avoid damaging when over-voltage and over-current. The voltage do not output when it is preset. Press "output" the voltage will be output.Adjustable voltage and current: The voltage and current is adjustable from 0 to setting value.LED digital display: There are three digits to display voltage and current. Voltage display resolution ratio is 0.1V, and current is 0.01A.Constant pressure and constant flow function: When the output value exceed the setting value, the DC power supply will limit automatically to make it within setting value constantly. It indicate "CV" when it is constant pressure, and indicate "CC" when it is constant flow. The "CC" and "CV" will be changed automatically according setting value.Overload, Short circuit protective: When it is overload, the output value is setted automatically within the limits; When it is short circuit, the output value is stopped immediately to protect the DC power supply.@Input voltage: AC220V± 10% 50HzModelJC1803AJC1805AJC3003AJC3005AJC6003ARated Output ValueVoltage18V18V30V30V60VCurrent3A5A3A5A3APower54W90W90W150W180WLoad EffectVoltage≤ 4.8mV≤ 8.6mV≤ 6mV≤ 6mV≤ 6mVCurrent≤ 9mA≤ 13mA≤ 9mA≤ 9mA≤ 9mASource EffectVoltage≤ 4.8mV≤ 8.6mV≤ 9mV≤ 9mV≤ 9mVCurrent≤ 9mA≤ 13mA≤ 9mA≤ 9mA≤ 9mARipple(5Hz-1MHz)CV pp≤ 4mV≤ 4mV≤ 4mV≤ 4mV≤ 4mVCV rms≤ 2mV≤ 2mV≤ 2mV≤ 2mV≤ 2mVCC rms≤ 3mA≤ 3mA≤ 3mA≤ 3mA≤ 3mARead-back AccuracyVoltage ± 1%+20mv20mv20mv200mv200mvCurrent ± 2%+20mA20mA20mA20mA20mAInput VoltageAC220V± 10%SizeW*H*D(mm)155*130*270Net weight(kg)45.545.55.6
