MEAN WELL GD2 series: Gate-driver DC/DC converter - GD2-121809

Description

GD2-121809 — Gate-driver DC/DC converter

The MEAN WELL GD2-121809 is an isolated, unregulated GD2 gate-driver DC/DC converter optimized for IGBT and SiC applications. It accepts 10.8–13.2 V DC (12 V nominal) and provides bipolar +18 V / −9 V outputs relative to Common in an SIP7 package. The module has a 2 W total output rating; observe the separate rail-current ranges and temperature derating.
