Reviewing a Very Dodgy BSK-602 Adjustable Power Supply
1 min read
Summary
A cheap, cheerful adjustable power supply, the BSK-602, is tested and torn down by DiodeGoneWild on YouTube, with the results being less than impressive.
The unit is shown to be unstable, with drifting voltage when left to heat up, and an abysmal component selection with no safety features.
The secondary side of the unit heats to over 150C, with one component reaching 190C; this caused the case to deform and a sticker to peel off during testing.
Such power supplies are apparently quite common on sites like Alibaba for less than $5, but this model lacks certification and represents a dinner on someone’s table in China, according to one commenter.
They also wonder if this sort ofbuild quality would be found in other cheap, low-cost products.
