Description
The HWD series provides onboard conversion of standard telecom and datacom input voltages into two isolated low-voltage outputs. These products offer a unique combination of wide input range, low profile, and high current capability. High efficiency and advanced thermal management enable these half-brick products to deliver full rated power at 55°C ambient temperature, with 200 LFM airflow, without the addition of heatsinks.

* Module will operate within specification with an input voltage of 18 Vdc, but must be turned on with an input voltage > 19.5 Vdc. See Undervoltage Lockout Specification.
Caution: This DC-DC converter is not internally fused. An external input fuse must always be used.
