HT DCDC 48-4.2/600-Ø42mm (200W)


The NSE DCDC 38/42-series is a high performance, high temperature DCDC converter for demanding applications. It is targeted at downhole wireline and drilling tools in addition to other industrial applications where high temperature and large variation in input voltage may occur.

The NSE NSE DCDC 38/42-series has a specified input voltage range of 100 (50) – 600Vdc. Output voltage can be factory set in the ranges 20-40Vdc (NSE-5002-17-series) and 48-60Vc (NSE-5002-15-series), and the converters can provide up to 4.2A output current over the entire operating temperature. Maximum operating voltage for short intervals is however 700Vdc. Voltages above this limit will cause it to shut down in protective mode. Maximum survival voltage is 900Vdc for one second.

The NSE DCDC 38/42-series is equipped with output short circuit protection that will protect the converter from failing even though its outputs are directly short circuited.

In order to operate reliably at high temperature, the DCDC has high efficiency (> 93%), reducing the dissipated power to a minimum.

The NSE DCDC 38/42-series PCB layout is made with ruggedness in mind. A CNC machined aluminum chassis provides maximum mechanical support to allow the board to operate in a very high shock and vibration environment. The board has rugged power input and output connectors.
