Review conclusionWith reservationsWith reservations

Only in one review: In test 135 W (RPS-120-27); No load 3.5 W (БП120Б-Д9-24C); Temperature rise 125 °C (БП120Б-Д9-24C); Price 110 $ (БП120Б-Д9-24C).

БП120Б-Д9-24C: Output power and voltage regulation match the specifications, but the unit runs hot and is expensive.

RPS-120-27: Well built and handles load tests, but it buzzes noticeably, has high ripple, and is difficult to repair.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
