Pros & Cons

Pros

  • ✓ Intelligent charging mode shows real-time Ah and auto-stops when the battery is full
  • ✓ OCP button arms overcurrent and short-circuit alarm that cuts output
  • ✓ Compact 7.59 x 3.35 x 6.1 in footprint, under 2.3 lb for a crowded bench
  • ✓ Six-layer protection: grounding, leakage, thermal, voltage, power overload, short circuit

Cons

  • ✗ 30V/10A ceiling rules out higher-voltage bench work above 30 volts
  • ✗ Switching design, so it is noisier electrically than a linear supply for RF work
  • ✗ Cooling fan only kicks in past 122F/50C, so heat builds before it spools up
  • ✗ Single output channel - no dual or tracking rails for op-amp supply work

Manufacturer description

Press the OCP button and the supply watches for short circuits and overcurrent events, sounding an alarm and cutting output before your project board pays the price. Kungber layers in a grounding wire, leakage protection, voltage and power overload protection, short-circuit protection, and a thermal cutoff that spins up the cooling fan above 122F/50C. At under 2.3 lb…
