Lab (or pseudolab for DPS5015) PSUs 3.3v power-up
Small comparison.
Small comparison.
It’s based on a copper plate, big old whipped aluminium radiator and two 100Ohm resistors, 800watt each.
Big battery capacity:
Received prebuilt battery and few elements: Big one is pretty heavy and overqualified for QRP 🙂 18Ah is enough to drive 100watt

It’s build from 250w 50Ohm resistors.
Finally got the clamp. Some simple tests with DMMCheck+
Not the best look, because this box already has a holes, but result is pretty nice:
Not good at all — heater 🙂
