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.
