Development of technological products. Laboratories. Product Type: KPS-3030DA Product weight: 9kg Product size: 337 × 263 × 173 ( L × W × H) mm Outline KPS-3030DA model power supply, adjustable for high efficiency switching power supply. It has with a load capacity, high reliability and efficiency, voltage and current continuously adjustable DC power supply, small size, light weight. Over-temperature, over voltage, overload, short circuit protection, suitable for the development of technological products, laboratory, teaching, electronic production lines, as well as the communications industry. Precautions AC input: AC input is 220V ± 10% 50Hz ( 110V ± 10% 60Hz in the back of the chassis will be marked) . 1. cooling: cooling fan at around the mouth and machinery ventilation should be sufficient space to facilitate cooling. This power machine equipped with a temperature switch will automatically rotate when the machine heating element temperature g 45 ° C fan cooling. Do not place the ambient temperature exceeds 40 ° C. Over-temperature protection: This power supply has over-temperature protection When machine heating element temperature exceeds 65 ° C, the output power off and wait for the power supply temperature cooling recovery of output function. Method of operation a) Connect the power supply ( AC220V ± 10% ) . b) Turn the power switch, the switch indicator is green. Adjust the voltage knob to the desired output voltage. 1. Connect external load to the " + " " - " output terminal. 2. constant current regulation: in the boot state, the current adjustment knob clockwise to the maximum, adjust the load current point to the desired setting, and then adjust the current knob counter-clockwise so that the voltage starts to fall under the ammeter current is required to set a constant current. 3. If you encounter header CC ( red) lights, the power supply is limiting state ( Any flow should header CV ( green) lights) . Note 1. Do not start with a load power switch, doing so can damage the power supply and the load. 2. This power supply is built-in thermistor to prevent instant boot overshoot Do not / boot, otherwise easily damage the power off in rapid succession. Service Replace the fuse If the fuse blows, the power supply will stop working, encountered such a situation must find out the cause of the blown fuse, and correct and then replace the fuse with the same value, in addition there is a problem generally fuse box do not open. ( 2) maintenance The power internal burns must be repaired by a professional electrical maintenance personnel, or send the dealer repair by the manufacturer and shall not be repaired to ensure safety. Warning: the KPS-3030DA switching power supply, internal high voltage lines, the non-professional maintenance personnel shall not carry out maintenance, to avoid danger. Power installation, use and maintenance instructions Maintenance of the installation, there are many special precautions for the following special instructions: a) After opening the package, please check carefully match the requirements of the Specification of the aircraft with the manual is consistent with the carrying, at the same time whether the order contract agreed. Event of any discrepancy, please contact our sales department to discuss ways to properly handle. As a first step before using, must be reliable grounding of the the atten power metal housing to ensure safety, but not mistakenly housing connected to the zero line. 1. before the installed power test run, check again and proofreading, make sure that the inputs and outputs, AC and DC, positive and negative voltage value and current value, no doubt correctly, put an end to then reverse fault, high-voltage short circuit from occurring. 2. The power does not allow for long-term is in full working condition, or they may be caused by man-made early failure. The order should be based on actual operating current to an allowance. 3. In order to achieve adequate cooling effect, the atten power should be installed in a location with good air convection conditions. General requirements for the power work should be well ventilated. In addition, the power supply housing are not allowed to place other items. 4. atten power applies mainly resistive load, if the need to apply mainly to capacitive or inductive-based load should be explained in the contract, due to an oversight of the nature of the load Lane wrong, it should be timely with our sales department contact to seek appropriate recovery plan. 5. For high voltage power supply, it is necessary to reiterate the importance of safety. The use of the process and power outages are not touch output port. 6. the atten power failure, in the most efficient way of delivering the same defective product to the Company, the Company will consider the situation, or to repair or replace. The user must not be allowed to atten power forcibly demolished, or will give the Company on the cause of the failure analysis to determine the cause difficulties and both suffered the loss.
