QHS DC-DC Series Data Sheet
Description
The QHS is a series of high efficiency, high-density, single output dc-dc converters for onboard conversion of
standard telecom and datacom input voltages into isolated low voltage outputs in a through-hole mounting
package. The two-board construction provides a cool environment for control components and the integrated
metallic substrate PCB provides superior thermal management for power components resulting in enhanced
product reliability. A heat sink can be conveniently and effectively attached to the IMS base plate for operations in
elevated ambient conditions or where airflow is minimal.
