Description

The QHS is a series of high efficiency, high-density, single output DC/DC converters for on-board 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

metalic substrate PCB provides superior thermal management for power components resulting in enhanced

product reliability. A heatsink can be conveniently and effectively attached to the IMS base plate for

operations in elevated ambient conditions or where airflow is minimal.
