Peak current rating on main output is 120% of max., lasting < 30 s with a maximum 10% duty cycle. 2. Ripple is peak to peak with 20 MHz bandwidth and 10 F (Tantalum capacitor) in parallel with a 0.1 F capacitor at rated line voltage and load ranges. 3. Class 2 means without input Earth pin. Replace-3 suffix with-II suffix to order class 2 product. 4. Combined output power of main output, fan supply and standby supply shall not exceed max. power rating. 5. Standby output voltage tolerance including set point accuracy, line and load regulation is +/-10%. Ripple and noise is less than 5%. 6. Fan supply output voltage tolerance including set point accuracy, line and load regulation is +/-30% and needs min. 1% load on main output to be within regulation band. Ripple and noise is less than 10%. 7. Class 2 product meets class A limit line for conducted emission. 8. Specifications are for nominal input voltage, 25C unless otherwise stated. 9. PSU is supplied with J3, pin-1 and pin-2 shorted to enable main output without remote on-off feature. 10. Derate output power linearly to 80% from 90 VAC to 80 VAC input. 74 Innovations in Power Mechanical Specifications AC Input Connector (J1) EARTH (J4) DC Output Connector (J2) Signal Connector (J3) Dimensions Weight Molex: 26-60-4030 Mating: 09-50-3031; Pins: 08-50-0106 Molex: 19705-4301 Mating: 190030001 6-32 inches Screw Pan HD Mating: 16 AWG wire crimped to Ring Tongue Terminal AMP: 8-31886-1 Molex: 22-23-2081 Mating: 22-01-2087; Pins: 08-50-0113 3 x 5 x 1.5 inches (76.2 x 127 x 38 mm) 450 g EMC CE Mark Conducted Emissions Static Discharge RF Field Susceptibility Fast Transients/Bursts Radiated Emissions Surge Susceptibility Harmonic Current Complies with LVD Directive EN55022-B, CISPR22-B, FCC PART15-B EN61000-4-2, Level-3 EN61000-4-3, Level-3 EN61000-4-4, Level-3 EN55022-B, CISPR22-B, FCC PART15-B To be controlled in end system EN61000-4-5, Level-3 EN61000-3-2, Class D Safety Safety Standard(s) EN60601-1, IEC 60601-1 (ed.3) Approval Agency Nemko Safety File Number(s)N069138 Signal Power Good Signal Remote Sense Remote on/off 75 TTL signal goes high after main output is within regulation band, delay is 0.1 to 0.3 s Compensates for 200 mV drop To turn-on PSU short remote pin to ground Derating Curve Mechanical Drawing DIRECTION OF AIRFLOW 5.000 [127.00] 0.120 [3.0] MAX HEIGHT BELOW PCB COMPONENT 4.550 [115.57] 0.225 [5.72] J4 N J1-1 J2-1 2.550 [64.77] 0.225 [5.72] 3.000 [76.20] L J2-2 COMPONENT ENVELOP J3-1 MOUNTING HARDWARE TOP AND BOTTOM CLEARANCE O 0.312[O7.9] 4-PLS 1.318[33.5]MAX MOUNTING HOLES O0.160[4.06] 4-PLS COMPONENT HT ABOVE PCB 1.500 [38.1] MECHANICAL OUTLINE DIMENSIONS ALL DIMENSIONS ARE IN INCHES [MM] GEN.
