BPS-48-40
48 V Power Supply
Description
BPS-48-40 aircraft power supply
BPS-48-40 is an aircraft electrical unit recorded in the existing technical card as a single-phase AC-to-DC power supply with a 48 V, 40 A output. These ratings are retained from the site’s earlier technical record, which may have originated from product documentation; the reviewed open web sources did not provide an independent exact-model data sheet. They should therefore be verified against the passport before procurement or testing.

Recorded electrical characteristics
The existing record specifies a 220 V input with a permissible deviation of minus 15 to plus 10 percent and operation from a 50 or 400 Hz single-phase source. The recorded output is 48 V at 40 A, with ripple no greater than 400 mV, total instability no greater than ±3 percent and efficiency of at least 85 percent. This places the unit within aircraft avionics and electrical equipment.
Reliability and identification
The same retained record gives mean time between failures of at least 30,000 hours and mass without the fan of no more than 7.6 kg. These figures describe the BPS-48-40 entry only and must not be transferred to BPS-48M or other similarly named units. Confirm the complete designation, nameplate ratings, connector arrangement, cooling configuration and drawing number.
BPS-48-40 installation and verification
The stated mass excludes the fan, which indicates that cooling configuration is part of installation selection and must be checked with the complete assembly record. Before connecting BPS-48-40, confirm whether the aircraft or bench requires the 50 Hz or 400 Hz input execution, verify protective devices and inspect the output connector. The retained electrical values are useful for identification, but the exact passport remains the controlling source.
Inspection and ordering
Inspect the enclosure, power connectors, mounting, cooling path, seals and plate. A bench test must use the documented input frequency and a controlled load; do not apply the maximum load before confirming the exact passport. State the complete designation, aircraft or equipment system, required output, quantity, condition and documents in the enquiry. Related units are listed under Electronic Control Units.
