AC-DC Power Supplies Bus Converter . Power Module Type TUNS300F, TUNS500F, TUNS700F, TUNS1200F Instruction Manual1 Connection for Standard Use!To use TUNS series, connection shown in Fig.1.1 and externalcomponents are required.!This product uses conduction cooling method (e.g. heat radiationfrom the aluminum base plate to the attached heat sink).Reference:“Derating”Table 2.2 Input Capacitor C1No.ModelVoltageCapacitanceRated ripplecurrent1TUNS300F2μF or more5A or more2TUNS500F2μF or more5A or more3TUNS700FAC250V3μF or more5A or more4TUNS1200F(85 to 264Vin)3μF or more5A or more5TUNS1200F(85 to 305Vin)AC300V3μF or more5A or moreAC INF1NoisefilterFG FGC1+S+VOUTAC1 TUNS300FTUNS500FTUNS700FAC2 TUNS1200FCo-VOUTFGR+BC -BC -SC3TFR1+C2CbcHeatsinkCY1Fig.1.1 Connection for standard useTable 1.1 External components+CY2LoadNo. Symbol Components Reference1 F1 Input fuse 2.1“Wiring input pin (1)”2 C1 Input Capacitor 2.1“Wiring input pin (2)”3 - Noise Filter4 CY1,CY2 Y capacitor2.1“Wiring input pin (3)”5 Co Output capacitor 2.2“Wiring output pin (1)”6 Cbc Smoothing Capacitor for boost voltage 2.3“+BC/-BC pins (1)”7 C2,C3 Capacitor for boost voltage 2.3“+BC/-BC pins (2)”8 TFR1 Inrush current protection resistor 2.3“+BC/-BC pins (3)”9 - Heatsink -2 Wiring Input/Output Pin2.1 Wiring input pin(1) F1 : External fuse!Fuse is not built-in on input side. In order to protect the unit, installthe fuse on input side (as shown in Table 2.1).Table 2.1 Recommended fuse (Slow-blow type)Model TUNS300F TUNS500F/ TUNS1200F TUNS1200F700F (85 - 264Vin) (85 - 305Vin)Rated voltageAC250VAC300VRated current10A15A25A25A(2) C1 : External Capacitor for input side!Install a fi lm capacitor as input capacitor C1 of which the capacitanceand ripple current capability are above the values shown inTable 2.2.!Use a safety approved capacitor.!If C1 is not connected, it may cause the failure of the power supplyor external components.(3) CY1, CY2 : Noise fi lter/Decoupling capacitor! The product doesn’t have noise fi lter internally.Please connect external noise filter and primary decoupling capacitorCY1, CY2 for low line noise and stable operation of the powersupply.! The operation of the power supply may be unstable due to theresonance of the fi lter or inductance.! Install a correspondence filter, if it is required to meet a noisestandard or if the surge voltage may be applied to the unit.! Install a primary decoupling capacitor CY1, with more than 470pF,near the input pins (within 50mm from the pins).! When the total capacitance of the primary decoupling capacitor ismore than 8800pF, the nominal value in the specifi cation may notbe met by the Hi-Pot test between input and output. A capacitorCY2 should be installed between output and FG.! For TUNS1200F65, CY2 should be connected regardless of thecapacity of CY1.In addition, the capacitance of CY2 is 2,200pF or more. CY2 capacitorsmust be certifi ed Y2 class safety standard.! CY1 must be certifi ed Y1 class safety standard.2.2 Wiring output pin(1) Co : Output capacitor!Install an external capacitor Co between +VOUT and -VOUT pinsfor stable operation of the power supply.Recommended capacitance of Co is shown in Table 2.3.!Select the high frequency type capacitor. Output ripple and startupwaveform may be infl uenced by ESR-ESL of the capacitor andthe wiring impedance.!Install a capacitor Co near the output pins (within 50mm from thepins).!When the power supply is used under 0C ambient temperature,output ripple voltage increases. In this case, connect 3 capacitorsCo in parallel connection.Table 2.3 Recommended capacitance Co[μF]Temperature of base plateModelTc=0 to +100C Tc=-40 to +100COutput voltage(V)TUNS300F/TUNS500FTUNS700F/TUNS1200FTUNS300F/TUNS500FTUNS700F/TUNS1200F1222002200×3parallel2810001000×3parallel48470470×3parallel65330330×3parallel!The specifi ed ripple and ripple noise are measured by the methodintroduced in Fig.2.1.TUNS-23
