Main uses
1. battery charging, PCB exposure lamp power supply
2. laboratory, electronic equipment, automatic test equipment
3. resistors, relays, motors and other electronic components aging, routine test
4. electronic inspection equipment, production line equipment, communication equipment testing
5. any other occasion requiring DC power supply
The company solemnly promised that the important components of the machine are imported devices

 In the use of power, be sure to confirm the input voltage (110VAC, 220VAC, 380VAC, 24VDC or 48VDC), and the nominal power use value is the same.
In the connection, be sure to cut off the input power. Carefully check whether the input and output lines are connected properly and firmly before power supply, to ensure the reliable power supply.
- check the installation screw and the power board device has no contact measuring insulation resistance and power supply input and output, so as to avoid the electric shock.
- in order to ensure the safety and reduce interference, ensure that the grounding end of reliable grounding (earthing wire diameter should be greater than AWG18#).

In order to make sure the power supply works normally and reliably, please don't overload the users when using the power supply.
- power multi output and auxiliary output, the main output characteristics are better than the auxiliary output, in order to ensure the output load adjustment rate and the dynamic output and other indicators, the general requirements of each with at least 10% load. If the auxiliary road does not use the main road, the main road must be loaded with more than 500mA.
- on a larger output power supply, the output terminal of a number of terminal users of terminals connected please uniform access load.
Output power - power mainly depends on the power devices. In order to ensure the reliable work of the power supply, we give a certain amount of power when there is a certain margin, customers should be consulted before overloading, in order to achieve the best use effect.
For the occasion of capacitive load and inductive load, the starting output current is too large at once. Our company has special design considerations in the development of power supply, please explain in advance.
- frequent switching on the power input (i.e. frequent opening and cut off the input voltage) will affect the life of the power supply.

In the purchase of motor users please note that the motor starting current moment, so please when buying power, the need to relax the current 2~3 times.

- JK series high precision adjustable DC power supply is designed for laboratory, school, factory production line, engineering department and maintenance units are designed, the output voltage can be continuously adjusted in 0 to the nominal value. The output load current is also continuously adjustable between 0 and nominal value, the power supply stability and ripple coefficient are very good, and there is a perfect overload protection circuit, which can be used as a regulated power supply, can also be used as a steady current power supply.

If you need to change or customize the power, you can contact us, 13962839257manager zhang
