This datasheet provides information on the ECONOLINE - DC/DC-Converter REC3-S/DRW(Z) Series, 3W, DIP24, Regul., Wide Input 2:1 & 4:1 (Single & Dual Output) series, including product model, input and output voltage, output current, efficiency, etc.
The REC3‑S/DRW(Z) Series from RECOM provides 3 W DC/DC conversion in a compact DIP24 package. It supports wide input voltage ranges (9‑18 V, 18‑36 V, 36‑72 V) and offers both single (+5 V, +12 V) and dual output configurations with regulated voltage.
Key features include up to 80 % efficiency, 1 kVDC isolation, short‑circuit protection, and a 25 kHz switching frequency. The device is specified for operation from –25 °C to +70 °C, uses a non‑conductive plastic case, and includes a Pi‑network input filter for low ripple and noise.
