76.0 x 76.0 x 10.7 mm (2.99 x 2.99 x 0.42 inch)
The 25-40 watts PKE 4000 series DC/DC power
modules are designed for decentralized 48/60 V dc
(36-75 V dc) power distribution systems with
distributed on-board DC/DC converters in
applications with high temperature and isolation
requirements. Their low profile allows narrow board
pitch and slim designs.
By using thick film technology, which provides a
high degree of integration as well as efficient thermal
management, and by utilizing 300 kHz switching
frequency based on proprietary drive and control
chips, the highly reliable products conform to the
most stringent telecom and data com requirements in
harsh environments applications. Mechanical
ruggedness, in conformance with IEC 68-2, is close
to the requirements for discrete components.
The converters can operate in free convention with
full output power at ambient temperatures from – 45
to +85 °C, making the products ideal for the most
demanding temperature requirements in both indoor
and outdoor applications.
