RFS30/40/60S S, RFS50/50L/60/100/120/150-RDS40/60/60S/100/120/150 (S of RDS40),, -S Reference 4.3 "Remote ON/OFF" 4.4 "Remote sensing" Connect resistance to set the output voltage as below.

In order to protect the unit, install the normal-blow type fuse on side. Table 3.1 Recommended fuse (normal-blow type) RFS30/40- RDS40 Rated current RFS50/50L RFS60/60S- RDS60/60S RFS100- RDS100 RFS120- RDS120 RFS150- RDS When the voltage from a front end unit is supplied to multiple units, install the normal-blow type fuse in each unit. When the fuse is open, power good signal is not outputed. (2) External capacitor on the side Install an external capacitor Cin, between and pins for low line-noise and for stable operation of the power supply. Table3.2 Recommended external capacitor(ceramic) Recommended Ci Vin=5V Vin=12V RFS30/40/60S-RDS40/60S 8 22mF 4 22mF RFS50/50L/60/100-RDS60/ mF 4 22mF RFS120/150-RDS120/ mF 2 22mF Cin is within 5mm for pins. Make sure that ripple current of Cin is less than its rating. When an impedance and inductance level of the line become higher, the voltage may become unstable. In that case, the voltage becomes stable by increasing Cin. (3) Recommendation for noise-filter Install an external filter as shown in Fig.3.1 in order to reduce conducted noise. Cin is shown in Table 3.2.

It is possible to protect the unit from the reverse voltage by installing an external diode as shown in Fig.3.2. IN Fig.3.2 Reverse voltage protection 3.2 Wiring output pin When the RFS/RDS series supplies the pulse current for the pulse load, please install a capacitor Co between and pins. + Co Pulse Fig.3.3 wiring external output capacitor Table 3.3 Recommended Capacitor and max Co Recommended Co MX Co RFS30/40/60S-RDS40/60S 3 100mF 10,000mF RFS50/50L 2 100mF 10,000mF RFS60-RDS mF 10,000mF RFS100-RDS mF 20,000mF RFS120/150-RDS120/ mF 10,000mF The output ripple voltage may grow big by resonance with Co and ESL of the wiring, if resonance frequency and switching frequency are close. Ripple and Ripple Noise are measured, as shown in the Fig.3.4. Co0, Co1, Co2 and Co3 is shown in Table mm 1mm 1mm1mm 4 Function 4.1 Overcurrent protection Over Current Protection (OCP) is built-in and works at 105% of the rated current or higher. However, use in an overcurrent situation must be avoided whenever possible. The output voltage of the power module will recover automatically when the fault causing overcurrent is corrected. When the output voltage drops after OCP works, the power module enters a hiccup mode where it repeatedly turns on and off at a certain frequency. 4.2 Thermal protection When the power supply temperature is kept above 120C, the thermal protection will be activated and simultaneously shut down the output. The output voltage of the power supply will recover automatically when the unit is cool down. 4.3 Remote ON/OFF The remote ON/OFF function is incorporated in the circuit and operated with and. If positive logic control is required, order the power supply with -R option.

Wire between & and between -S & as short as possible. Loop wiring should be avoided. This power supply might become unstable by the noise coming from poor wiring. (2) When the remote sensing function is in use -S Wire as close as possible Fig.4.3 Connection when the remote sensing is in use Twisted-pair wire or shield wire should be used for sensing wire. Thick wire should be used for wiring between the power supply and a load. Line drop should be less than 0.5V. Voltage between and should remain within the output voltage adjustment range. If the sensing patterns are short, heavy-current is drawn and the pattern may be damaged. The pattern disconnection can be prevented by installing the protection parts as close as a load. -Y1 This is change the open loop characteristics accelerated while using remote sensing with a large external capacitor on the output side.
