The output mode is determined by the voltage and current values set by the user and the load that the user receives . The output voltage or current value of the power supply will not exceed the voltage and current value set by the user. In the constant voltage mode , the output voltage is equal to the voltage set by the user. In constant current mode, the output current value is equal to the current value set by the user. Voltage Regulation 1. Adjust the voltage roughly to the required voltage value , the fine-tune the knob to the required specific voltage value2. In general , the current knob can be adjusted to the maximum , and then the load can be connected for use Current regulationWhen the user needs to adjust the limiting current output1. firstly , adjust the voltage to about 5-10V , then short-circuit the positive and negative terminals with wires ( short-circuit alarm needs to be set to C C position )2. Adjust the current to roughly adjust the knob to the required current value , and then fine-tune the knob to the required specific current value3. After disconnecting the short-circuit conductor and adjusting the required voltage by voltage regulation " method , the connection load can be used Packing List1 x whole machine 1x Power cord1x Output Load Line 1x Instructions PaymentDelivery detailsTerms of salesAbout usContact usPayment We accept ebay payment 。Fees such as import duties, taxes are not included in the item price or shipping costs.
