Description
The quarter-brick RP90Q series DC/DC converters are designed for railway rolling stock and high voltage battery
applications. Each series has three 4:1 input voltage range options to cover all input voltages from 9VDC up to
160VDC with isolated and regulated 5V to 48VDC outputs. The converters have high efficiencies and metal base-
plates to permit a wide operating temperature range from -40°C to +85°C (when mounted on a suitable heatsink).
The case is fitted with threaded inserts to allow secure mounting to the PCB or bulkhead for use in high shock and
vibration environments. The converters are EN50155 and IEC/EN60950 certified. The RP90Q-RW series have a
three year warranty.

Ordering Examples
RP90Q-2405SRW/N = 24V Input, 5V Output, Single, Neg. CTRL function
RP90Q-11012SRW/P = 110V Input, 12V Output, Single, Pos. CTRL function
RP90Q-2405SRW/N-HC = 24V Input, 5V Output, Single, Neg. CTRL function, with premounted Heat-sink
Notes:
Note2: standard part is with suffix “P” for positive logic (1=ON, 0=OFF)
or add suffix “N” instead for negative logic (0=ON, 1=OFF)
Note3: add suffix “-HC” for premounted Heat-sink
(compatible with all other suffixes)
