    I tested the unit and the results are verygood: - open circuit voltage 11.9V - loaded voltage: 11.8V at 5A - maximum output current 6.3A - steady-state temperature: 60dgr.C the case, 110 drg.C the transformer (at 5A after 1 hour).

    Delivered in 15 days (Tver). Bought on promo. There was no seal, so I opened it. No EMI filter (input) - promo?. Capacitor 33uF - to low for 60W. Incomplete output filter (no choke) - as result Vpp > 100mV. Loaded with 40W lamp for 15 minutes - transformer ~70C, case ~50C. Does not whine with load.

    Very attractive priced PSU for LED strip power. Simple and compact AC/DC power supply. See images for PCB layout. The distance between high voltage (!) AC 230V and DC circuitry could be better, e.g. more safety distance on the PCB layout. When used @ 4A load during 1 hour, the unit gets almost 50 degrees inside the enclosure and about 38 degrees on the metal housing.

    For this price it is pretty good power source. I tested it for load current from 1.9A up to 4.9A. The results from oscilloscope are in attached figures for current 1.9A, 3.4A and 4.9A. Measured values for 1.9A load were DC voltage Vavg=11.9V, peek-to-peek voltage Vpp=0.5V. Measured values for 3.4A load were DC voltage Vavg=11.9V, peek-to-peek voltage Vpp=0.7V. Measured values for 4.9A load were DC voltage Vavg=11.9V, peek-to-peek voltage Vpp=0.84V. I measured also temperatures of board and metal cooler.

    It works well, I tested at 4A for 2 hours and behaved well from a thermal point of view.
