About the BW5521
A flat, rack-width sheet-metal power supply. One long side has an IEC mains inlet with a switch and fuse holder, marked MAINS IN, RANGE 85-265 VAC, FUSE 3.15 AT, use only original fuses, with vents on each side. The opposite side carries two D-sub combination connectors with high-current contacts for the DC outputs. The case label reads Mat BW5521, with a serial number and Rev 01.
The 'Mat' label and number style match AVL material numbers. The unit came from AVL engine test cells, and it looks the same as the AC-input units listed as B05207/BO5207. AVL does not publish this number, so we cannot confirm which system it powers or its output voltages.
Frequently asked questions
Is BW5521 the same as B05207?
The photos show the same housing, mains inlet markings and output connectors. We have not confirmed whether the different number is a newer revision or a different build.
What output voltage does it supply?
No output rating is visible on the labels, and we found no AVL data for BW5521. Please check the output pins before you connect any equipment.
