PSE250 - DC/DC Industrial Converter

Product Overview


POLYAMP  DC/DC Industrial Converters

Polyamp provide free standing DC/DC converters, which means they meet EMC, EMI, electrical safety requirements and can be installed in any weather protected environment. The units are air cooled, convection cooled and can mostly be mounted in any direction.

The EMC performance is such they can be mounted in low noise applications. The output ripple is among the industries lowest. The immunity levels meet tough requirements in substations, trains, vehicles, railway and industrial applications. We have also models that meet EN50022 special low noise Telecom environment.

The mechanics are based on sturdy aluminum cases, that provides conduction cooling, mechanical stability for any type of vehicles, trains, locos, ships, marine, military rubber wheel vehicles. All units can be mounted on chassis, mounting plate, wall also with TS35 DIN rail. Most units are 19"-rack modular 2U, 3U, 6U.

Polyamp can provide special mechanics solution and systems based on our units, as well as Secure 2x N+1 redundant systems for power utilities, off shore applications and many more.

Polyamp production system is ISO9001:2008 certified

C-Tick AS/NZS CISPR11: 2002 Group1 Class A
A Overvoltage protection (OVP): The output voltage is limited to 15% nominal output voltage. A thyristor short- circuits the output
B Undervoltage alarm with relay: The logic alarm output is replaced with Relay with selectable alarm logic NO or NC.
C Built in series diode: A series diode on the output, when output is connected in parallel with other power supplies to achieve redundancy. Output power might be derated by 20%
S The voltage sensing can be put at the load to compensate for voltage drop. This is standard feature on 5V output.
H Inrush current limit with NTC: Only for C-input code. Reduce the inrush current during the start up. The input voltage range will be affected.
E1 2.5kVac isolation input/case, option: On A and B inputs. The emission level increase to level A.
E2 2.5kVac isolation output/case: The emission level will increase to level A.
T Train input: Input voltage range according to train Standard EN50155 and IEC 60751. Euro panel, option L 8TE for PSE 100, 10TE for 5V output with extra cooler.
L Euro panel: 8TE for PSE 150 & PSE 200, 10TE for PSE 250.
N Wall mounting panels: Wall mounting panel with connector holder. The female connector has to be chosen. H15 screw type female, H15-S - H15 fast-on 6.3mm female, H15-T - Din rail TS35 clips, option Q
