SPECIFICATIONS
Ac Input 85-264 Vac, 47-63 Hz single phase. Input Current Maximum input current 3.7 A at 90 Vac, 60 Hz with full rated load. Input current harmonic content meets the requirements of IEC1000-3-2 Class A for all load conditions. Hold-upTime 25 ms minimum from loss of ac input at full load, nominal line (115 Vac). Minimum Load: No minimum load required Output Power 250 W fan cooled, 180 W convection. See chart for models under 12 V. Overload Protection Fully protected against short circuit and output overload. Short circuit protection is cycling type power limit or foldback type depending on model and output. Recovery after fault is automatic. Individual output current limits are a function of load distribution and degree of overload. Output Noise 0.5% rms, 1% pk-pk, 20 MHz Bandwidth, differential mode. Measured with noise probe directly across output terminals of the power supply. Transient Response Main Output–500 μs typical response time for return to within 0.5% of final value for a 50% load step change, Di/Dt< 0.2 A/μs. Maximum voltage deviation is 3.5%. Remote Sense Provided as a standard feature. Capable of compensating for 0.25 V total of cabling losses in voltage. Overvoltage Protection Built in on all models. Output voltage decay is dependent upon loading. Voltage Adjustment Main output ±5%. Efficency Minimum 80% on 12-48 V units, 75% on 5 & 3.3 V units at full rated load. Input Protection Internal ac fuses provided on all models. Fuses do not blow on overload or short circuit—fuses blow only if catastrophic failure occurs in the unit. EMI/EMC Compliance All models include built-in EMI filtering to meet emissions requirements: EMI SPECIFICATIONS Conducted Emissions GPFC250 Conducted Emissions GPFM250 Static Discharge RF Field Susceptibility Fast Transients/Bursts Surge Susceptibility COMPLIANCE LEVEL EN55022 Class B; FCC Class B EN55011 Class B: FCC Class B EN61000-4-2, 6 kV contact, 8 kV air EN61000-4-3, 3 V/meter EN61000-4-4, 2 kV, 5 kHz EN61000-4-5, 1 kV diff., 2 kV com.
