High Precision with 4 Digit and Backlit Display Design: SKY TOPPOWER 30V 5A DC variable power supply is a professional power supply device;The accuracy can be accurate to 0.01V(10mV)and 0.001A(1mA),and has extremely sensitive coarse fine knobs can turn smoothly and easily adjust it within 0-30V and 0-5A;Has backlit 4-digit large and segmented display screen, is crisp and bright,visible easily even in the low-light conditions
Constant Voltage and Current Mode Automatic Conversion: The bench power supply constant voltage and current mode could automatically switch with load changes;The conversion of CV and CC is indicated by the LED display on the position below the knob;if the load current is less than the preset current limiting value,it could be as a constant voltage source;lf the load current becomes equal to or greater than the preset current limit,the unit will automatically switch to the CC mode and the voltage will drop
Compact and Lightweigh:The unit is smal,takes up very little room on the bench, easily to carry, only 8.70X5.43X4.09 inch and the weigh less than 1.5kg
Safe Reliable to Use: Lab power supply has ground terminal provide security protection measures when operated;It also has Leakage protection,Thermal protection,Voltage overload,Limit current ,Short-circuit protection and anti-reverse connection protection to better protect your device from damage;Build-in cooling fan that provide stable and reliable working status,the shell was cool to the touch with excellent heat dissipation, effectively prolong the life of product
Widely Used: It suitable for testing components,circuits,laboratory, electronic,communication equipments maintenance, products lines, charging batteries,scientific research and teaching units, nice present choice for IT Pro and DIY hobbyist, a good assistant for beginners
