This mini DC power supply is a single set of output, high precision double display switching DC 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. Perfect line protection function. Apply for sticking technology small size, good appearance. Using multi-circle wire-wound potentiator with high efficiency. The cooling system for intelligent temperature control fan. Set of posts could dual-use (insert or connect), prevent the posts heat and loose. High-precision LED digital display, intuitive and clear. 8 cm intelligent fan, excellent heat dissipation, effectively extend the life of the fan and reduce noise. Using advanced technology, it effectively reduces the weight of the power supply and facilitates power supply movement. Multiple protection functions, current limit protection (OCP), over temperature protection (OTP), over power protection (OPP). Plastic panel, more beautiful, voltage and current set coarse adjustment and fine adjustment knob to make the setting more precise. Application areas: Laboratory, factory, maintenance power supply, product aging, such as resistors, capacitors, relays, DC motors, LEDs, etc. Specifications: Material: ABS Plug: US, EU, UK Line voltage: AC 110/240V10% 60Hz/50Hz Output voltage: 0-30V Output current: 0-10A Voltage display accuracy: 0.5% Current display accuracy: 0.5% Efficiency: 85% Display: LED Digit Display Display Accuracy: 1%1 Operating Ambient: -10to +/30%RH to 90%RH Dimension: 70*160*220mm Weight: 1300g Package size: 28*21*12cm/11.02*8.26*4.72in Package weight: 1724g Voltage Regulation: Load regulation (10-100%): 50mV Line regulation (200-240V AC): 20 mV Ripple & Noise (P-P): 50mV Current Regulation: Load regulation (10-100%): 20mV Line regulation (200-240V AC): 20 mV Ripple & Noise (P-P): 20mV Note: Item color may show sight aberration due to different shooting light and monitor display.
