Auto C.V. and C.C. Mode
When you connect the load two things can happen:
- (1)The load requires more current than the maximum you set.
- (2)The load requires at most the maximum current you set.
- In the first case the PSU become a current source: the current is limited to what you set and voltage drops accordingly, that's CC for you.
- In the second case what is costant is the voltage, so that's CV.
Bright Green Led Display
Precision and accurate with 3 digit display reaches to 100mv,10mA that easy to read.
Accuracy Adjustment
Coarse and fine adjustments knob designed, and easy for you to adjust your desired value.
Compact Design & Lightweight
60volt power supply is designed in small size 226*82*138mm, and weight only about 2.95lb. very easy to carry.
How to Charge Battery
- 1.Please turn on the dc power supply , and preset the voltage needed.
- 2.Connect to the battery.
- 3. Please make sure the voltage of the dc power more than the battery one, that's V1> V2, and then the power supply could charge the battery.

電圧及び電流か可変でき重宝してます、使用上の注意はバッテリーに繋ぐ前に供給電圧測定、電流にしてから繋いて下さい逆流防止の為。

Purchased this to anodize aluminum in the .58 square foot size using the low current density method. Also successfully used it for etching aluminum. Works well for constant current. Numbers were easy to read, and no overheating problems with 2 hour runs. I didn’t test it for accuracy against a multi-meter. It has no hum. Nice small profile.

I have two of these. Well I used to have two, I'm down to one now. It's a nice form-factor and they're light. Unfortunately, one of them died about an hour ago and fried a client's custom single board computer in the process. I've been using the supply 6-8 hours a day, sometimes letting it run over night, supplying about 300 mA @ 12v to some client hardware.About an hour ago I noticed that the supply was off even though the switch was on. I swapped over to the other supply and the customer board immediately sent the power supply into current limiting. So something's fried, won't know what until we do failure analysis.Anyway, beware of these cheaply-made supplies. I no longer trust the remaining one and need to find something better now.

リチウム電池４本の内１本で電圧低下を検出、この機器で個別セルを満充電にしたのち組上げたら正常になりました。その後も問題無く使用出来てます。

This power supply unit works great. But after almost one year of daily use, it broke. I got a very strong burning smell one day and the power supply soon stopped working. After contacting the seller, I got a response within hours. Sent in some pics of the internals for them to confirm the issue. Eventually a replacement unit was sent out under warranty. I am very happy that my set up is working again!

Both voltage and amperage are easily adjusted with both coarse and fine adjustments. The posts are set up to take a variety of leads and has side holes to accommodate a simple wire without end plugs. For the money, it's solid. I use it to inject voltage into various areas of motherboards for troubleshooting and it is helpful to have a power supply that can lock the voltage and draw current as needed or lock the current and draw voltage as needed. The display is quite clear and large enough to see at a distance well beyond arms length. Hope this helps.

This is a review of the NaviTech NP3010H power supply received on 9/23/2019.Low voltage and low current setting control is good. Turn coarse voltage or current all the way to zero when needing low values.Voltage adjustment: With coarse voltage = 0V, fine adjusts from 0.00V to 3.55V, with 0.01V precisionCurrent adjustment: With coarse current = 0A, fine adjusts from 0.000A to 0.958A, with 0.001A precisionMeter accuracy (Agilent 34411A 6-1/2 digit multimeter used for these measurements) VoltageSet VoltageMeasured 0.80V 0.799V 1.20V 1.194V 3.30V 3.291V 5.00V 4.991V 10.00V 9.983V 20.00V 19.994V 30.00V 29.901V 32.00V 31.906V CurrentSet CurrentMeasured 0.100A 0.0896A (25ohm load) 0.500A 0.4885A (25ohm load) 1.000A 0.9715A (0ohm load) 2.000A 1.9505A (0ohm load) 3.000A 2.9307A (0ohm load) 5.000A 4.8940A (0ohm load) 10.00A 9.82222A (0ohm load) 10.18A 10.0002A (0ohm load)Power supply noise (Tektronix MDO4104B digital oscilloscope with 20MHz bandwidth limit enabled for these measurements)50.2mV peak-peak, 2.45mVrms (25ohm load at 12V, DC-20MHz, 100Meg samples/sec)26.3kHz time domain switching peaks6.02MHz and 14.1MHz frequency domain peaksStartup Transient Response9.3ms 10-90% rise time from cold turn on 0 - 12V into 25 ohm load21.5ms settling time to within 50mV of 12V (25ohm load)19.8ms settling time to within 50mV of 12V (no load)No overshoot in either case.Note: Current limit must be set high enough to remain in voltage mode. If not, I did see 0.58V overshoot on the 12V startup transient.Shutdown Transient Response89ms 12V to 0.5V into 25 ohm load6.00s 12V to 0.5V into no loadShutdown transient response depends upon the load, and if there's no load, can take 6 seconds from only 12V.Front panel binding posts lack a center hole to thread heavy gauge wire through. Wire tends to slide off the binding posts even when tight. If you bend the wire in a half circle the diameter of the binding post, it holds better. This is the weakest feature of this power supply.Current metering accuracy is pretty bad at low currents, 10% error at 0.100A current set.Besides the two above negative points, the rest of the power supply performs very well for a switcher. I really like how small and lightweight it is.I'm using it for power input to a 3-phase stepper controller to drive a brushless DC motor, power for a 12V air mattress blower, power for a 12V compressor to pump air for car tires, and power for charging sealed lead-acid batteries on replacement UPS (uninterruptible power supply) batteries.When charging the valve regulated sealed lead-acid batteries, I use 14.2V with a current limit of 1A. The changeover from 1A current limit to 14.2V voltage limit is smooth as the current drops to less than 50mA @ 14.2V when fully charged.
