Applications Manual DCS1400 2. Connection for Standard Use 2.1 Pin configuration 2.1 Connection for standard use ■To use the DCS1400 series, external components should be connected as shown in Fig.2.1. ■The DCS1400 series should be conduction-cooled. Use a heatsink or fan to dissipate heat. Fig.2.1 Connection for standard use... -
Page 5: Input Fuse: F11
Applications Manual DCS1400 2.2 Input fuse: F11 ■Fuse is not built-in on input side. In order to protect the unit, install a fuse shown in Table 2.2 in the input circuit. (as shown in Table 2.2) Table 2.2 Input voltage Rated Voltage Rated current range... -
Page 6: Output Capacitors: Co, C21
Applications Manual DCS1400 2.4 Y Capacitors and noise filters: CY, CX, L11, L12 ■The DCS1400B doesn't have noise filter internally. Install an external noise filter and capacitor (CY) to reduce conducted noise and stabilize the operation of the power supply. ■Noise filters should be properly designed when the unit must conform to the EMI/EMS standards or when surge voltage may be applied to the unit. -

Applications Manual DCS1400 3.2 Output voltage adjustment in parallel operation(CV) ■When adjusting the output voltage in parallel operation, connect the VTRM terminals together and adjust them together. ■By connecting the external potentiometer (VR1) as shown in Fig.3.2.,output voltage becomes adjustable. See formula① 5 ×... -
Page 9: Constant Current Adjustment In Parallel Operation(Cc
Applications Manual DCS1400 3.3 Constant current adjustment in parallel operation(CC) ■By adjusting the voltage of one ITRM, it is possible to adjust the constant current of all power supplies connected in parallel. It is not necessary to connect all ITRM terminals. ■By connecting the external potentiometer (VR2) as shown in Fig.3.4.,constant current becomes adjustable. -
Page 10: Remote Control
Applications Manual DCS1400 3.4 Remote control ■When using remote control in parallel operation, control the remote control terminals of the power supplies in parallel at the same time, as shown in Fig.3.6. ■Do not connect RCG terminals to each other. The RCG is connected to -Vin terminal inside the power supply, and connecting them to each other can form a loop circuit, potentially causing the power supply to malfunction. -
Page 11: Other Functions
Applications Manual DCS1400 4. Other functions 2.1 Pin configuration 4.1 Power Good ■By using PG, it is possible to monitor power supply whether normal operation or abnormal operation. The PG signal is "Low" when the power supply operates correctly. The signal turns to "High" when the power supply stops. ■The PG signal sequence is shown in Fig4.1. -
Page 12: Output Current Monitor
Applications Manual DCS1400 4.2 Output Current Monitor ■ The output current can be monitored by voltage between the CB and -S. ■ Fig.4.2 shows the relationship between the voltage of CB terminal and the output current. The output current shown in Fig.4.2 is for reference only. ■... -
Page 13: Mounting Method
Applications Manual DCS1400 5. Mounting method 2.1 Pin configuration 5.1 Mounting method ■When implementing the power supply to the printed circuit board, please fix the power supply to the printed circuit board by screw before the soldering. If it is screwed to the substrate after soldering, there is a possibility of failure by adding mechanical stress to the soldering point and the internal connections of power supply. -
