MEAN WELL SPAN02 series: Regulated SIP DC/DC converter - SPAN02A-03

Description

SPAN02A-03 — Regulated SIP DC/DC converter

The MEAN WELL SPAN02A-03 is an isolated, regulated single-output SIP8 DC/DC converter in the 2 W SPAN02/DPAN02 family. It accepts 9–18 V DC (12 V nominal) and provides 3.3 V DC, with 0–500 mA. The 3.3 V version is limited to 1.65 W by its 500 mA output-current rating. Remote ON/OFF control is provided; observe the pin-specific control and thermal limits.
