PS-302DF 30V/2A Four-Digit Display Adjustable DC Regulated Switching Power Supply for Notebook Repair Laboratory Test
This mini DC Voltage Current power supply is a single set of output, high precision LED display switching DC Voltage Current power supply. With overload protection and constant voltage/current features. Application areas: Charge the battery, Car DVD, car audio, product aging, such as resistors, capacitors, relays, DC motors, LEDs, etc. Features: Single phase, single output, low ripple and noise. High-precision three-group four-and-a-half LED digital display: current + voltage + power, intuitive and clear. Intelligent fan, excellent heat dissipation, effectively extending fan life and reducing noise. USB interface, 5V/2A output. Adopt advanced technology, effectively reduce the weight of the power supply, lengthen the handle design, and facilitate the power movement. Regulated steady current constant current constant voltage multiple modes can be switched. Set the coarse and fine adjustment knobs for voltage and current to make the setting more precise. Multiple protection functions, current limit protection (OCP), over temperature protection (OTP), over power protection (OPP). Application areas: Laboratory, factory, maintenance power supply, product aging, such as resistors, capacitors, relays, DC motors, LEDs, etc. Specifications: Output voltage: 0-30V Output current: 0-2A Display accuracy: 4-digit LED digital display, display accuracy ±0.1% ± 1 word Input voltage: AC220V/110V±10% 50Hz /60Hz±2Hz Working temperature: -10 ° C -40 ° C Relative humidity <90% Storage temperature: -10 ° C -70 ° C Relative humidity <80% Regulated state: Voltage stability ≤ 0.01% + 3mV Load stability ≤ 0.01% + 5mV Recovery time ≤100us Ripple noise ≤1mVrms Temperature coefficient ≤300PPM/°C Steady flow state: Current stability ≤ 0.2% + 3mA Load stability ≤ 0.2% + 3mA Ripple noise ≤ 3mArms (effective value) Voltage resolution: 10mV Current resolution: 1mA Note: Item color may show sight aberration due to different shooting light and monitor display.
