Aging of factory product test: such as DC motor, DC fan, car DVD, car stereo, resistor, capacitor and other products of aging test.2. Battery charging industry: It is perfectly applied to the battery charging industry. It provides constant current charging and then converts to constant voltage trickle charge to prevent overcharging, protect the battery, and effectively prolong battery life.3. Inverter industry: Overcoming the stuck-in problem of linear power supply relay switching, extremely speeds, and meeting instantaneously varying load requirements.4. LED manufacturing industry: LED testing, aging.5. Other occasions that need DC power supply. Tips:1. Ventilation: Radiator at the rear of the equipment should Not be Blocked out.2. Please read the user's manual before use.3. Please allow 1-2cm errors due to manual measurement.4. Due to the difference between different monitors, the pictures may not reflect the actual color of the item.
