AC-DC Power Supplies Enclosed TypeInstruction Manual? PBA300F, PBA600F, PBA1000F, PBA1500Fand PBA1500T!These models have a built-in remote sensing function.If you do not use the remote sensing function, you can short outbetween +S and +M and between -S and -M on CN1.When the power supplies are shipped from a factory, they comewith a dedicated harness (H-SN-19) being mounted on CN1. Ifyou do not use the remote sensing function, you can use thepower supplies as they are.!Please see Fig.1.4 if you do not use the remote sensing function.Please see Fig.1.5 if you use the remote sensing function.!When you use the remote sensing function, please wire from+S and -S on CN1. Harnesses are available for your purchase.Please contact us for details.When you use the remote sensing, please note the followings.1Wire carefully. When a connection of a load line becomes loose(due to such factors as loose screw), the load current fl ows tothe sensing line and internal circuits of the power supply may bedamaged.2Use a suffi ciently thick wire to connect between the power supplyand the load and keep the line drop at 0.3V or below.3If the sensing line is long, connect C1 and R1.4Use a twisted pair wire or a shielded wire as the sensing line.5Do not draw the output current from +M, -M, +S or -S.6When the remote sensing function is used, the output voltageof the power supply may show an oscillating waveform or theoutput voltage may dramatically fl uctuate because of an impedanceof wiring and load conditions.Please check and evaluate carefully before using the remotesensing function.If the output voltage becomes unstable, we suggest you to trythe followings.- Remove the remote sensing line on the minus side and shortout between -S and -M.-Connect C1, R1 and R2.Please contact us for details.CN1CN1+M+S-S-M+V-V+M+S-S-MC1Short at CN1(H-SN-19)Wire the sensing linesas close as possibleR1LoadFig.1.4 When not using remote sensing function1.9 Alarms? PBA300F, PBA600F, PBA1000F, PBA1500Fand PBA1500T!Alarms (PG signal) are generated from CN3. Please see Table1.2 for the functions of the alarms. The objective of the PG signalsis to detect whether or not a certain function of a power supplyis working. It takes several seconds to generate the alarmsignals and the timing when the alarm signals are generated is inconsistent.Please check if the objective of the alarm is achieved.PGTable 1.2 Description of the alarms (PG signal)AlarmThe PG signals are”Low”whenthe power supply operatesnormally.The signals turn”High”when thefan stops or the power supplystops as a result of output voltagedecrease/stop, activation ofthermal protection, overvoltageprotection or overcurrentprotection functions.One of three phase is open(PBA1500T)0.1 FFig.1.6 Internal circuit of PGOutput of AlarmOpen collector methodGood: Low(0.5V max at 10mA)Bad : High or Open50V 10mA max100kWPGPGG!Please note the followings when you use the alarms (PG signal).1 The time it takes until the PG signals turn”High”vary dependingon models and conditions.PBA300F and PBA600F….. less than 1 secondPBA1000F, PBA1500F and PBA1500T….. less than 10 second2 If the output voltage is turned off through a remote ON/OFF circuit,the PG signals turn”High”.3 The PG signal may turn”High”, if the output current of one unitbecomes 10% or below of the rated current in parallel operation(in this case, the fan also stops).4 If the output voltage is decreased to almost 0V or decreasedrapidly through an external adjustment mechanism when load islight, The PG signal may turn”High”.!The PG signal (Alarm) circuit is isolated from input, output, FG,RC and AUX.+V-VR2C1LoadFig.1.5 When using remote sensing functionPBA/PBW-40
