Datasheet

COO (Country of Origin):: TW

RECOM Switching Regulator, 89% Efficiency, ±1% Line Regulation - R-78HBXX Series - R-78HB12-0.5L

Maintain a steady power supply to your equipment with this switching regulator from RECOM. Thanks to an 89% efficiency level, minimal energy is lost through heat so the unit runs cool. Compact dimensions of 11.5 (L) x 17.5 (W) x 8.5mm (D), as well as 90° L-shaped pins, mean it's a suitable choice for busy setups. You can use it safely in demanding conditions thanks to a broad operating temperature range of -40°C to +85°C. Thanks to an output current of 500mA, it's suited to low-powered machinery.

Features & Benefits

• Input voltage of 17 to 72V DC and output voltage of 12V DC for low-voltage applications
