Before & after. I can't stand when manufacturers use black post nuts for all terminal posts. Now I need yellow post nuts instead of green. I buy matching terminals just to swap the nuts. So far, only one other seller uses yellow for ground post. #Hanmatek #LONGWEI

Interesting bug on the #Hanmatek HM605T while trying to adjust the Over Current Protection. It doesn't matter what digits are selected.

#KiPrim (#OWON) DC310S & #Hanmatek HM605T have an identical startup, probably very similar circuit design. However the KiPrim DC is very noisy.

#Hanmatek HM605T rise & fall time showing on #Rigol #DHO900 #Oscilloscope under 2A load using #Hantek current probe & #EastTester #ET5410A+ DC Electronic Load. Current has a consistent surge 75ms following the voltage rise. Load is on when pushing the output button.

#Hanmatek HM605T mosfets clock in at 54Khz shown on #Rigol DHO900. I was expecting 150Khz so will have to check the specs. Blue trace on #Siglent SSA3021X shows harmonics directly from DC Output.

Load testing the #Hanmatek HM605T to its max, 309 watts. While measuring common mode noise on #Rigol DHO900 #Oscilloscope. Surprisingly, the power supply stayed fairly cool. #EastTester crap. #Electronics

Tried to load test the #Hanmatek HM605T to 400 watts with #EastTester DC Electronic Load and discovered it has another mosfet shorted to ground. At least the OCP worked on the power supply. Won't be buying East Tester Test equipment anymore.

#Hanmatek 605T load test, but the #Siglent SDL 1020X-E max is 210 watts. Lots of switching noise inside the case.

▶️動画アップ久々の動画は直流安定化電源HM310のレビューです。ついでに電子負荷も買って動作確認してみました。動画が長くなってしまったので、次回後編では直流安定化電源でノートPCを動かしてみます。 #すいラボチャンネル #直流安定化電源 #電子負荷 #HANMATEK https://t.co/uUNuzsZH8S
