Power Supply Units

Power supply units are designed to convert and stabilize electric power in aircraft systems. They produce stable output voltage even when the input power parameters and load change.

BP-48 power supply unit specifications: Input supply voltage: 115 VAC / 400 Hz or 27 VDC. Input battery supply voltage: 27 VDC. Stable output voltage: +24 V, +5 V, +27 V, -24 V, +15 V, -15 V. Input overvoltage protection current: 3 A.

BP-59 power supply unit specifications: Input voltage: 115 VAC / 400 Hz / 0.4 A. Unregulated output voltage: 27.5 V /1.6 A.

BP-48, BP-59

The operating principle is based on conversion of the input AC or DC voltage to the required output using transforming, rectifying and stabilizing elements.

BP-48 and BP-59 are aviation-grade power supply units (secondary power sources) available in enclosed version as electronic modules with power and converting components mounted inside shielded metal casing.
