Flatpack2 DC/DC Converters (18–75 V, 380/48 V) — modular DC voltage converters

Description

Flatpack2 DC/DC converters convert a DC voltage of one level into a DC voltage of another level with galvanic isolation. Some modules produce a secondary output of 310–400 V from a main 48 or 60 V battery — for powering small remote sites without a mains supply; others step down a 380 V bus to 54 V with an efficiency of 98.2 % for data centres. The galvanically isolated CAN bus connects to the power management system, so a separate controller is not required.

Main features: wide input voltage range; OR-ing protection at the output; high efficiency — up to 98.2 % for 380/48 V modules; seamless integration into the power management system via the CAN bus; modular design, high power density (33 W/in³ for the 380/48 V module).

Versions in the series: 42–75 V → 380 V / 1350 W, 18–75 V → 24 V and 48 V / 1350 W, 380 V → 48 V / 3000 W SHE (2U unit up to 24 kW).

Technical data (depends on version): Output power — 1350 W / 3000 W (SHE); Input voltage — 18–75 V DC; 260–400 V DC (380/48 V); Maximum output voltage — 400 V DC (380 V at output) / up to 55 V DC; Efficiency — 94.5 % / 98.2 %; Operating temperature — −40…+75 °C; Dimensions — 109 × 41.5 × 327 mm; Degree of protection — IP20.

Applications: data centres (380 V DC bus); telecommunications and remote sites without a mains supply; railway infrastructure and industry.
