30V 5A DC Power Supply Precision Variable Digital Adjustable 110V
Uses:
Ideal for scientific research,product development,laboratories,universities and mobile computer repair,etc.High precision and good techinique to protect the product safety and reliability.This DC Power Supply features a very high quallity variable 0-30V and current 0-5A.Comes with high reliability,low noise and circuit overload Protection.
User Notice:
Be sure to adjust the rear button to a proper voltage for working performance,or it will cause damage to machine. For any damage caused by user's false use, we assume no responsibility.
Under normal condition, the USA voltage is 110V, the specific use depends on real demand.
When using, please pay attention to the connection of the output end, to avoid short time contact short circuit caused by the output terminal negative spark.
Warning:
- Please read the user manual before using the DC regulated power supply.
- Do not connect any load to the power supply before it's turned on. Likewise, make sure to disconnect the load before shutting down the power supply. Damages to the power supply can happen if you do not follow this. Such damages are not under warranty.
- If you are running inductive load like magnetic coils, DC motors, stepper motors, etc. Make sure to change the voltage/current slowly, and never turn the power supply on or off with an inductive load connected.
Features:
1. Portable size, practical and convenient to operate
2. Auto shift between voltage stabilization and current stabilization
3. It has rather low ripple voltage
4. LED screen displays output voltage and current
5. Selectable over-current protection, widely applied to daily fields
6. Adjustable design could meet your various demands
7. With 4pcs potentiometers, respectively for output voltage and output current
8. High precision and stability
9. Short Circuit Protection,Over Loading and Current Protection
