The GNT400 provides 400 W of DC output power in a compact package. Standby,
control and monitoring inputs and outputs provide all the essential elements for a
variety of applications including, single board computers, running motors, pumps,
and solenoids. Approval to EN60601-1 and EN60950 improves design-in time and
reduces end system compliance costs.
