AC-DC Power Supplies Confi gurable TypeInstruction Manual3.9 Constant output current adjustment(Applying module : E4-H4, E-H, S-V, V4, V5, 2C-2M)!The constant output current can be adjustable by the external voltageapplied to between ITRM and COM on CN3. When the ITRMterminal voltage is set at less than 2.5V, the output current will bebased on the calculation 2.Do not set the external voltage of the terminal to -0.3V or less, and5.0V or more.When the output current is adjusted to around 0A, the unit mightbe unstable.The external resistor or voltage is required for the constant outputcurrent adjustment.The voltage betweenITRM and COM [V]Output current [A] = XRated output current [A] --- 22.5 [V]2 The built-in fan does not stop even if the output is turned OFFby the remote ON/OFF.3 When the output is turned off by the remote on/off, the LV alarmwill be delivered.4 This function individually operates on each output module.!The Remote ON/OFF circuit on each output module can operateindividually.The detail of the“Global inhibit function”to turn all output modulesoff at the same time is shown in the item 3.13.CN1AUXAUXGOutput moduleRi=1.8kΩOutputoffRCSWOutputonRCGCN3* When using output module V5, use the rated output current ofoutput module V.10kΩ5VITRM100kΩ470pF 100kΩCOMFig.3.4 ITRM Internal circuitNote :!If the output voltage becomes less than 5% of the rated voltageduring constant current operation, the output may be unstable.Please evaluate the unit under actual conditions carefully beforeusing the constant current function.!When the output impedance is low like the high capacitive load,the output may be unstable. Please contact us for the detail.3.10 Remote ON/OFF(RC)!Each output module have remote ON/OFF functions. The outputvoltage can be turned on/off by the signal to RC terminal in CN3on each modules.!The remote ON/OFF circuit (RC, RCG) is isolated from the input,outputs, FG and other function terminals.!Auxiliary power (AUX) for remote ON/OFF.The power supply has the auxiliary power (AUX) for the remoteON/OFF.The auxiliary power (AUX) is isolated from the input, outputs, andFG.Fig. 3.5 is the example of the remote ON/OFF with AUX.!Please note the followings for the remote ON/OFF function.1 The output stops when 4.5V to 12.5V of the voltage is appliedto RC.Fig.3.5 Example of remote ON/OFFTable 3.1 Remote ON/OFF specifi cationConnection methodFig3.5 Remote SWSW openOutput onSW(0-0.5V between RC and RCG)LogicSW shortOutput off(4.5-12V between RC and RCG)Bases pinCN3 RCG3.11 Remote sensing(Applying module : E4-H4, E-H, S-V, V4, V5, 2C-2M)! These models have the remote sensing function.When the remote sensing is not used. +S and -S can be left open.! Please see Fig.3.6 if you use the remote sensing function.! When you use the remote sensing function, please wire from +Sand -S on CN3. Harnesses are available for purchase.For details, refer to the item of option parts.! Please consider the following when using remote sensing.1 Be sure connections are made properly. If the load wire is notconnected correctly, a load current may flow through the sensingwire, which could damage circuitry inside the power supply.2 Wire of an appropriate type and gauge should be used to connectthe power supply to the load. Line drop should be less than0.3V.3 Use a twisted pair wire or a shielded wire as the sensing line.4 Do not draw the output current from +S or -S.5 The impedance of the wiring and the load might cause problemssuch as the unstable output voltage and bigger output voltagefluctuation.When the output voltage is unstable, C1, R1, R2 in Fig. 3.6 willbe effective.6 When power supplies are connected in parallel, the remotesensing function is not available.AME-17
