iETong DC LAB BENCH POWER SUPPLY -0-30V, 0-10A Adjustable

iETong variable voltage power supply is a simple, accurate Constant Current (CC), Constant Voltage (CV) DC power source that provides the displayed currents and current up to the listed ratings.It is designed for factory maintenance and scientific research, product development, laboratories, schools and electronic production lines.

High Precision with 4-Digits LED Display

• This little adjustable dc power supply is specially designed to supply DC power to external devices, with separate current and voltage settings.
• At the same time desktop power supply is a professional power supply regulation device that has a high resolution of 0.01V and 0.001A. Thanks to its large LED display, you can view the output voltage and current settings easily and conveniently.You can adjustment it within 0-30V and 0-10A.
• Note : After you turn on the power and set the voltage according to the instructions, you need to wait for a few seconds and then turn on the power again, which can effectively retain the voltage data you set.
• Note : When you set constant voltage (C.V.) & current (C.C.) mode,the V and A settings you set are the crossover point at which the mode switches.
• CV Mode : CV stable voltage Indicator is on under stable voltage working status
• CC Mode : CC stable current indicator is on under stable current working status

DC Power Supply -Charge Different Batteries

• Bench power supply can also charge your batteries: lithium batteries, lead-acid batteries, electric car batteries, lawnmower batteries, etc. It can meet your many needs.

Intelligent cooling fan:

• The adjustable power supply includes temperature control fan,when the internal temperature of the power supply reaches a certain temperature, the fan automatically turns on for heat dissipation,and when the temperature drops, the fan will automatically stop, which can effectively extend the service life of the DC power supply and can reduces the noise allows you to use the product consistently and effectively.

Safety protection

• This easy-to-use benchtop power supply not only comes with fuse protection, but also has grounding protection, overheating protection, current limiting protection, voltage overload protection and short circuit protection, and reverse connection protection.

(FAQ)：About iETong dc power supply:

• Frequently Asked Question (FAQ)：
• 1.Q: When I power it on, the current displays show zero, is it normal?
• A: If it isn't connected to a load it should read zero because no current is flowing. This variable dc power supply requires manual current and voltage settings.
• 2.Q: How do I get the Bench power supply to stay in constant current mode?
• A: CC is attained when the rated set current is exceeded. It would stay in that mode till the current drops back to the preset.
• 3.Q:How to set the current value without load connecting?
• A: Please short the +/- outputs together, set the current, and remove shorting cable.You could also refer to the operation instruction.
• 4.Q: Does it remember the last settings when turned off and back on again?
• A: Yes, because it's on a dial. If you don't adjust it and just flip the on and offswitch in the front it will remain the same.
• 5.Q:How to switch between Constant Voltage (CV) and Constant Current (CC)?
• A:The supply will do it automatically. Turn the current down or up to adjust the limit. When the mode CC shifts to CV, the CV i ndicator light turns on. You can adjust it to any value. It automatically switches to CC when the set current value is exceeded.
