SynQor Develops Higher Power Versions of its RailQor DC-DC Converters for Rail
Boxborough, MA - SynQor announces the addition of two higher power DC-DC Converters
to its RailQor line of products. These new converters triple the usable
power in the Quarter Brick footprint to 150W. In the Half Brick package
the power capability is increased to 252W, five times the level that was previously
available. These ruggedized, next-generation, board-mountable, isolated,
fixed switching frequency DC-DC converters use synchronous rectification to achieve
power conversion efficiencies up to 91% at full load and 93% at 50% load; while
still maintaining 80% or greater efficiency at light load. Each module
is supplied completely encased with an aluminum baseplate to provide protection
from harsh environments.
The new Quarter and Half Bricks come in four different input voltage ranges: 9-36V,
42-110V, 66-160V and 12-155V. There is a selection of standard output
voltages (5, 12, 15, 24) and power levels (up to 252W) that make the RailQor line
of converters suitable for a variety of systems in locomotive and railway electronics.
The robust RailQor DC-DC converters permit an operating baseplate temperature range
of -40°C to +100°C. These converters will deliver maximum output
power with minimal to no derating as long as the baseplate is maintained at 100°C
or below. Please consult the derating charts available in the datasheets
for your specific application environment.
The versatile RailQor converters are designed to address EU EN50155 standard requirements
for "Railways Applications Electronic Equipment Used on Rolling Stock". The
use of fixed switching frequency technology provides predictable EMI performance,
which greatly simplifies filtering design.
The RailQor line of DC-DC converters feature on/off control referenced to the input
side, remote sense for the output voltage and an output voltage trim range of -20%,
to +10%. Protection features include input under-voltage lockout, output
current limit and short circuit protection, active back bias limit, output over-voltage
protection and thermal protection. All models have at least 1000Vdc,
100Mohm REINFORCED input-to-output isolation and calculated MTBF values in excess
of 1MHrs, and they are fully 6/6 RoHS compliant.
The RailQor product line is available for evaluation and qualification. Production
quantities are available with 8-week lead-times. For information on our
evaluation board and meeting railway transient requirements please click here for our application note. For more
