Space-rated power conditioner
boasts highest efficiency
K-rated device's 90% efficiency enables size
and weight reductions in other system
components A full-bridge-topology device with secondary
synchronous rectifiers operating at 200 kHz, the
space-rated Electronic Power Conditioner operates
at an efficiency of 90%–the highest of any such
device. This efficiency enables spacecraft system
designers to reduce power management circuit size
and weight while meeting electrical system
performance requirements. Input voltage ranges from 26 to 43 V with a
typical output power of 56 W. The main output
voltage can be externally set between 6 and 8 V
at 8.5 A, with secondary output voltages of
±5 V at 0.4 A each. Custom input and output
voltages are also available.
Features include bus current telemetry, on/off
telecommand and output sequencing, overcurrent
protection, undervoltage lockout, and an EMI
filter. The device is Class K rated per
MIL-PRF-38534. (From $15,250–available now.)
