SPECIFICATIONS*1 This is the result of measurement of the testing board with capacitorsof 22mF and 0.1mF placed at 150 mm from the output terminals bya 20 MHz oscilloscope or a ripple-noise meter equivalent to Keisoku-Giken R104.See 1.6 of Instruction Manual for more details.*2 Drift is the change in DC output for an eight hour period after a half-hourwarm-up at 25C.Features*3 Consult us about dynamic load and input response.*4 Output power derating is required. Refer to "Derating".*5 See 4 in Instruction Manual for more details.*6 Consult us about safety agency approvals for the models with optional functions.*7 The fan speed slows down at no load.*8 Consult us about other classes.*9 The RC terminal is added to option ?R models. The RC terminal isPJMA300FCASE SIZE/WEIGHT102X41X190mm [4.02X1.61X7.48 inches] (Excluding terminal block and screw) (WXHXD) / 1.0kg maxOTHERSCOOLING METHOD *7 Forced cooling (internal fan)WARRANTY WARRANTY *5 5 years (subject to the operating conditions)isolated from input, output, and FG.* Do not use the power supply in overcurrent conditions or in unspecifiedinput voltage ranges. Otherwise the internal components may bedamaged.* Parallel operation is not possible with this mode.* Sound noise may be heard from the power supply when used forpulse load.PJMA- 4kV isolation- Economical design- Suitable for BF application (Output-FG : 1MOPP,lnput-Output : 2MOPP)- Wide temperature range (-20 to +70 , Refer to“Derating”)- Harmonic attenuator (Complies with IEC61000-3-2 class A)- Universal input (AC85 - 264V, Refer to "Derating")- Low power consumption at no loadBlock diagramAC IN85 - 264VFUSEAC(L)250V10AAC(N)250V10ANOISEFILTERRECTIFIERINRUSHCURRENTLIMITFGBOOSTERINDUCTORCURRENTSENSINGRECTIFIERANDFILTERCONTROLCURRENTSENSINGCONTROLOVER VOLTAGEPROTECTIONINVERTERINVERTERRECTIFIERANDFILTERDC OUTCONTROLTHERMALPROTECTIONCONTROLFANExternal viewThe external size of ?V option and ?R option models is different from the standard model.
