  • Simple, accurate, functional
Style: 30V 10A 4-Digital
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. ... show more

  • Extremely nice supply for the money
Style: 60V 5A 4-Digital
After trying out a few other budget options, this on is a definite keeper. Let's start with the CONS.... - The potentiometers are touchy. Even the the "fine" know feels way too touchy when you get the 4 digit unit. I would have liked muti-turn knobs a lot better, but to be honest, the knobs are OK, just not perfect. - The fan speed is proportional to the current drawn, not how hot the power supply is. This is weird, but hey, it's a pretty small con. - Depending on how clean of a power supply you need and how quick of a reaction you need, this PS may not be ideal for you. I haven't tried it on radio equipment yet, but there are a few tens of millivolts of noise and the output capacitors are fairly large so the transition from CV to CC is relatively small and may burn current-sensitive components like LEDs if you set your voltage too high and count on the CC to save you. And now for the PROS... - This power supply does pretty much what it needs to do and at $120 for the 300W 4 digit version, it is definitely worth it. I have charged lead acid batteries, excited alternators, and run digital electronics at all sorts of voltages and current levels for long hours and the power supply keeps going and doesn't get hot. The current and voltage displays are very close to my Fluke 87 and someday I will calibrate both to get even more confidence out of the reading. You don't really need the 4-th digit as the accuracy is not that great, but I find it convenient to have for not that much extra $ The form-factor of this PS is amazing. It is tiny, light and convenient. I don't know how to praise it more.... All I can say is: If you're in the market for a mid-range bench power supply and if you can afford this, definitely get this on. I needed the 60V option where the offerings are more limited and this product fit my bill and needs perfectly. I would have payed a little more for a 10A version if one was available and as nice as this one. ... show more

  • A good portable switching power supply with only a couple negative points
Style: 30V 10A 4-Digital
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 precision Current adjustment: With coarse current = 0A, fine adjusts from 0.000A to 0.958A, with 0.001A precision Meter 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 peaks 6.02MHz and 14.1MHz frequency domain peaks Startup Transient Response 9.3ms 10-90% rise time from cold turn on 0 - 12V into 25 ohm load 21.5ms 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 Response 89ms 12V to 0.5V into 25 ohm load 6.00s 12V to 0.5V into no load Shutdown 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. ... show more

  • Product works well; customer support is great
Style: 60V 5A 3-Digital
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! ... show more

  • Works, is pretty easy to use, and is overall good
Style: 30V 10A 4-Digital
It was somewhat difficult to understand how to set the amps, but after I figured that out it was easy to set voltages. It has a high enough max operating environment temperature to work in Phoenix and is accurate to 0.05v according to my multimeter (which is pretty accurate but may add a small amount to the inaccuracy). It has overall worked well and continues to do its job, which, for me, is allowing me to run electronics without needing a dc adapter for every single item. ... show more

  • Burned out at soon as the return window was up
Style: 60V 5A 3-Digital
Worked great when I first got it. Moderately accurate, easy to use, no issues. Then almost as soon as the return window was up, tried to power it up, smelled smoke, and now the leads are electrically linked with zero resistance, not usable for anything. Money 100% wasted, very disappointed in this product. ... show more
