Only in one review: Power 250 W (DPH5005); Under load 8.163 V (RBQ-8,2/45); Ripple 100 mV (DPH5005); No load 4 W (RBQ-8,2/45).

RBQ-8,2/45: A genuine converter with high efficiency and high output current; at room temperature it can deliver 15–16 A without extra cooling.

DPH5005: The converter showed good calibration, low heating and ripple up to the specified 100 mV, but input current is limited to 10 A.
