OVERVIEW The PR-241 is a unit integrates the functions of our AC/DC power supply units and rectifiers listed below. • AC/DC power supply unit PR-240, PR-300 • Rectifier unit RU-1746B-2, RU-3423, and RU-3424. Important notices The specifications of PR-241 have been changed to be compatible with DC bypass. The DC compatible unit has a white dot as shown in the figure below.
• When using in dual, do not input from multiple AC power supplies or batteries. Due to the difference in the load characteristics of the battery and the PR-241, it may not function as a power supply.
The mounting procedure is as follows: 1. Referring to the outline drawing at the back of this manual, make four pilot holes for self-tapping screws (4x16, local supply) in the mounting location. 2. Place the unit in a fixed position and align the screw holes. 3.
