COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Enclosed TypeInstruction ManualIf the remote sensing is not used, the following terminals of CN1must be shorted:+S and +M?S and ?MWhen the power supply is shipped from our factory, a designatedharness (H-SN-31) is attached to CN1. If remote sensing is notused, there is no need to remove the harness.-The wire connection when remote sensing is used or not used isshown in Fig. 6.14 - Fig. 6.15.-When using remote sensing, make sure to fi nish wiring +S and ?S fi rst. The designated harness is available for sale. Contact usfor more details.-When using remote sensing, pay attention to the following:1 Wiring must be done carefully. If there is bad connection on theload lines due to loose screws, etc., the load current fl ows intothe sensing lines and the internal circuit of the power supply maybe damaged.2 Make sure the wires between the load and the power supply arethick enough to keep the line drop less than 0.3V.3 If the sensing wires are long, place C1 and R1 across the loadlines.4 Use a twisted pair wire or a shielded wire for the sensing lines.5 Do not draw the output current from +M, ?M, +S or ?S.6 The impedance of the wiring or the load may cause the outputvoltage to oscillate or fl uctuate.Test to confi rm remote sensing works fi ne. If the output voltage isfound to be unstable, the following methods are recommended:- Remove the remote sensing line on the minus side and short?S and ?M.- Use C1, R1, and R2.? ?T (PJA100F, PJA150F)-The ?T option models come with a vertical terminal block.The appearance is different from that of the standard models.Contact us for more details.V.ADJM3.5AC(L)AC(N)FG( )Outputterminal(-)Outputterminal(+)Fig.6.16 Example of option -T(PJA100F)? ?J (PJA100F, PJA150F)- The ?J option models come with EP connectors (Mfr. Tyco ElectronicsAMP) instead of a terminal block.- The designated harnesses are available for sale.
