Traits:This electronic load uses IR feed tube and double ball rolling fan, with fin heat sink, which is not afraid of dust and can guarantee stability for long use, the power redundancy is not less than 50% (25). Classic digital tube display, intuitive and hard, compared to LCD screen, it is more resistant to a high temporary. It can return voltage and courrure during constant discharge of Carent, visually reflecting the dischargeVoltage wiring connectors and crowns are the section, with proper connection it can eliminate the influence of wire resistance.100% factory power to factory, suitable for automatic combustion power adapter-cabinet assembly FEATURES: Supply voltage: DC12V ( 5%) (equipment supply voltage)Maximum charging voltage: 100vConstant current discharge setting range: 0-20aWorking mode: constant current mode()Maximum discharge current error: 0.7%-0.01aMaximum discharge power: 250W
