The SKYTOPPOWER STP3010 Regulated DC Power Supply 30V 10A (110/220V AC Switchable) 3 1/2 LED Display is a regulated DC power supply that allows you to adjust the current and the voltage continuously. It uses LED to display the value of the current and the voltage. And the output terminal is a 4mm "banana" jack. It can be used in electronic circuits such as the operational amplifier, digital logic circuit and so on. With quick response and high accuracy, it surely is worth your investment!<!--Features --><p>FEATURES</p><UL><LI>Leading technology: new PWM switch for voltage stabilization, MOS linear secondary voltage stabilization</LI><LI>Energy-saving and high efficiency: over 80% high efficiency, 40% higher than other liner power supplies on market</LI><LI>Lightweight: less than 1.5kg, only 50% of other linear power supplies on the market</LI><LI>Intelligent temperature control: new technology, adjustable fan revolving speed based on load power, noise reduced and life prolonged</LI><LI>Quick response: microsecond load response speed</LI><LI>Safe and reliable: equipped with overload protection, overheating protection, overvoltage protection, short-circuit protection, etc.</LI><LI>Use LED to display the value of the current and the voltage</LI></UL><!--Specifications --><p>Specifications</p><TABLE class=ke-zeroborder cellSpacing=0 cellPadding=0 width="100%" border=0><TBODY><TR><TD width=131>Model</TD><TD width=365>STP3010</TD></TR><TR><TD width=131>Input Voltage</TD><TD width=365>110V/220VAC÷10% Switchable</TD></TR><TR><TD width=131>Frequency Range</TD><TD width=365>50/60Hz</TD></TR><TR><TD width=131>Output</TD><TD width=365>DC 0~30V,0~10A</TD></TR><TR><TD width=131>Load Regulation</TD><TD width=365>●0.3%+5mV</TD></TR><TR><TD width=131>Ripple</TD><TD width=365>●10mVrms</TD></TR><TR><TD width=131>Operating Temperature</TD><TD width=365>0→ ~ +40→</TD></TR><TR><TD width=131>Storage Temperature</TD><TD width=365>-10→ ~ +70→</TD></TR><TR><TD width=131>Storage and Operating Humidity</TD><TD width=365>●80%RH</TD></TR><TR><TD width=131>Altitude</TD><TD width=365>●2000m</TD></TR><TR><TD width=131>Pollution Degree</TD><TD width=365>2</TD></TR><TR><TD width=131>Dimensions</TD><TD width=365>(8.90 x 3.23 x 5.43)" / (22.6 x 8.2 x 13.8)cm (L x W x H)</TD></TR><TR><TD width=131>Material</TD><TD width=365>Sheet Metal &amp; Plastic</TD></TR><TR><TD width=131>Color</TD><TD width=365>White</TD></TR><TR><TD width=131>Weight</TD><TD width=365>50.09oz / 1420g</TD></TR><TR><TD width=131>Plug Type</TD><TD width=365>US Standard</TD></TR></TBODY></TABLE><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-2.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-4.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-5.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-6.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-7.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-8.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-9.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-10.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-11.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-12.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-13.jpg"><IMG alt="" src="http://www.image-tmart.com/info_images/23003863-14.jpg"><!--Package Includes --><p>Package Includes</p><UL><LI>1 x Power Supply</LI><LI>1 x Plug Power Cable</LI><LI>1 x English User Manual</LI></UL><!--Extra Info --><!--produts_compatibility -->
