Product Description Product DescriptionPower Supply High school teaching power for School Lab (Physical Instrument)Junior high school teaching power supply: This power supply for school lab is mainly a graded continuously adjustable high-current protection DC regulated power supply, with good voltage stability and small ripple, and has 5A, 40A and AC output functions. It is a general and necessary instrument for junior high school teaching demonstration experiments. It can also be used in technical vocational schools, normal schools, and teaching experiments.Product Specification ModelJunior high school student power supplyJunior high school teaching power supplyHigh school student powerHigh school teaching powerOutput voltage1.5V-9V DC regulated output, six gears1.5V ,3V ,4.5V ,6V ,9V ,12V ,regulated output,six gears1.5, 2, 3... 16V single and double selection sixteen gears adjustable2~24V, one gear per 2V, a total of 11 gears can be adjustedRated current1.5A2A2A2V-6V,12A8V-12V,6A12V-24V,3AVoltage stabilityEach gear is not more than 350mVEach gear is not more than 350mVThe output of each gear is not more than 2%U standard +0.1VThe output of each gear is not more than 2%U standard +0.1VCurrent stabilityEach gear is not more than 350mAEach gear is not more than 350mA------Ripple voltageEach gear is not more than 15mVEach gear is not more than 15mVWhen each gear is fully loaded, it is not more than 0.1% U markWhen each gear is fully loaded, it is not more than 0.1% U standard + 5MVProtectionWith overcurrent protectionBetween IХ (1.05-1.6), automatic protectionWhen the output current is between 1.05 and 1.5 times of the rated current, the output can be automatically turned offWhen the output current is between 1.05 and 1.5 times of the rated current, the output can be automatically turned offAmbient temperature0~40oC0~40oC0~40oC0~40oCRelative humidity≤80%(40oC)≤80%(40oC)≤90%(40oC)≤85%(40oC)voltage150 V~248V,50Hz220V±10%220V±10%50Hz±5%220V±10%50Hz±5%operating hourscontinuousContinuous voltage regulation (except 40A, 5A)Working continuously for not less than 8 hoursWorking continuously for not less than 8 hoursProduct feature and applicationThis power supply for school lab is mainly used as a low-voltage AC and DC regulated power supply for junior high school and high school physics teaching experiments.Maintenance and precautions1. The power supply should be stored in a dry and ventilated place without corrosive gas to prevent the device from being damp, corroded and reduced in insulation.2. The power supply should be used within the rated load, and overloading is strictly prohibited.3. When using the pressure regulating switch, it should be gradually changed from low to high to avoid damage to the experimental circuit due to overvoltage or overcurrent.4. When the instrument is fully loaded and used continuously for a long time, the circuit chip of the instrument may be protected due to overheating. In this case, the load can be reduced or the internal temperature can be lowered before enabling it. Detailed PhotosCompany ProfilePackaging & ShippingFAQ
