Telecommunication Isolated Converter

24 V and 48 V input, single and dual output isolated DC-DC converters for telecommunications/network applications

Single and dual output isolated converters consist of next-generation, onboard, isolated, fixed-frequency DC-DC converters that use synchronous rectification to achieve extremely high power conversion efficiency. The converters consume very little power, so no heat sinks are required, thereby saving costs, weight, height, and application workload. All power and control components are installed on a multilayer PCB substrate. 

Operating features

Up to 97% ultra-high efficiency 

The maximum voltage withstand is 100 V, with an input voltage transient of 100 ms (only for PQ60 and PQ40 models) 

Fixed-frequency switch, low output noise 

No minimum load requirement (except for PQ60525HTA04) 

It is available as a fully functional option on certain models. 

Wide input voltage range: 

18 - 36 V (PQ24) 

18 - 60 V (PQ30) 

18 - 75 V (PQ40) 

35 - 75 V (PQ48, PQ60, DQ6) 

44 - 52 V (PQ50) 

38 - 55 V (PQ55) 

40 - 75 V (PQ65)

Bottom Plate Accessories

These technical appendices contain other specifications for the basic version of the telecommunication converter. These units are manufactured by adding industry-standard-sized bottom plates to non-bottom plate converters using standard installation techniques. The bottom plate version allows for optional cooling in harsh thermal environments or installation on a cold plate. For all the specifications not included in these appendices, please refer to the specific product data sheets.
