COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Enclosed TypeInstruction Manual5 Ground-V!When installing the power supply, make sure the FG terminal andthe chassis (at more than 2 places) are connected to the safetyearth ground.+VCN3126 Options and Others6.1 Outline of Options? ?C-With the ?C option, the internal PCB has a conformal coating foranti-humidity.? ?G (PJA300F, PJA600F, PJA1000F, PJA1500F)-With the ?G option, the leakage current of the power supply isreduced.-The differences between the option ?G models and the standardmodels are shown below.Table 6.1 Low leakage current typePJA300F/600FPJA1000F/1500FLeakage Current(AC240V 60Hz)0.15mA max0.2mA maxConducted NoiseN/AOutput Ripple NoisePlease contact us for details aboutRipple Noise* This is the result of measurement of the testing board with capacitorsof 22μF and 0.1μF placed at 150 mm from the output terminalsby a 20 MHz oscilloscope or a ripple-noise meter equivalentto Keisoku-Giken RM103.? ?V (PJA300F, PJA600F, PJA1000F, PJA1500F)-With the ?V option, the power supply comes with an externalpotentiometer connector instead of a built-in potentiometer.-The appearance of the ?V models is different from that of thestandard models. Contact us for more details.-Note that if the power supply is turned on with CN3 open, theoutput voltage will make a big drop.CN3+V +V? ?RFig.6.2 Front view of option-V (PJA1500F)-The ?R option makes it possible to switch on or off the output byapplying voltage to the RC terminals of the power supply froman external power source.-The appearance of the option ?R models is different from that ofthe standard models.-Designated harnesses for the RC terminals are available forsale. See Optional Parts for more details.-The ?R option models have extra connectors. Please contact usfor more details.Table 6.2 Remote on/off operating conditionsModel NameBuilt-inResistorRi [ W ]Voltage between RCand RCG [V]Output ON Output OFFInputCurrent[mA]PJA100F, PJA150F,PJA300F, PJA600F,PJA1000F, PJA1500F7804.5 - 12.50 - 0.5(20max)External PowerSourceR *1Input CurrentSWRemote ON/OFF connector (Optional)RCRCGInside of a PowerSupplyFig.6.3 Example of using a remote ON/OFF circuit*1 If the external voltage applied to the RC terminals is 4.5-12.5V, the current limiting resistor is not necessary. If the voltageapplied is more than 12.5V, make sure the current limitingresistor R is used.The value of the current limiting resistor is obtained by the followingformula:R[W]= Vcc-(1.1+RiX0.005) Vcc : External Power Source0.005* Note that reversed connection damages internal components ofthe power supply.* The remote control circuit is isolated from input, output and FG.RiV.ADJFig.6.1 Front view of option-V (PJA600F)!Remote on/off control for PJA100F, PJA150F, and PJA300F-Remote control connectors are added. Contact us for more details.-Make sure there is an interval of more than 2 seconds in the on/off cycle. If the interval is shorter, the start-up time may becomelonger (approx. 2 seconds).PJA-22
