SPECIFICATIONS
Ac Input
85-264 Vac, 47-63 Hz single phase.
Input Current
Maximum input current 2.3 A at 90 Vac, 60 Hz with full rated load. Input cur-
rent harmonic content meets the requirements of IEC1000-3-2.
Hold-up Time
25 ms minimum from loss of ac input at full load, nominal line (115 Vac).
Output Power
110 W fan cooled, 75 W convection. Peak ratings are for 60 s maximum dura-
tion, 10% duty cycle.
Total Regulation
Total regulation is the maximum deviation from the nominal voltage for all
steady-state loading conditions.
Overload Protection
Fully protected against short circuit and output overload. Short circuit protec-
tion is cycling type power limit. Recovery after fault is automatic.
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
500 μs typical response time for return to within 0.5% of final value for a 50%
load step change, ∆i/∆ t< 0.2 A/μs. Maximum voltage deviation is 3.5%. Load
must not go below stated minimum.
Remote Sense
Provided as a standard feature. Capable of compensating for 0.25 V total of
cabling losses in voltage. Open sense lead protection.
Overvoltage Protection
OVP crowbar reduces output voltage below nominal rating in less than 50 ms.
Voltage Adjustment: Main output ±5%.
Input Protection
Internal ac fuse provided on all models. Fuse does not blow on overload or
short circuit—fuse blows only if catastrophic failure occurs in the unit.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the EMC requirements below.

Inrush Current
Inrush 240 Vac is less than 37 A, averaged over the first ac half-cycle under cold
start conditions. Limiting provided by internal thermistors.
Fan Output
An additional output, same as Vout, suitable for powering a dc fan is included in all
models. The output is protected by an internal resistor in the event of an overload.
Power Fail
TTL or CMOS compatible output goes low (<0.5 V) 8 ms before output voltage
drops more than 4% below nominal voltage upon loss of ac power. The signal is
factory set to trip when input power can no longer sustain the output.
Temperature Coefficient
0.03%/°C typical on all outputs.
Environmental
Designed for 0 to 50°C operation at full rated output power; derate output current
and total output power by 2.5% per °C above 50°C. See Environmental and Pack-
aging Specifications on the next page.
Commercial Safety Approvals
All models are approved to UL1950, CSA22.2 No. 950-95, IEC950, EN60950. CB
certificate available. Exceeds FCC and CISPR22 Class B conducted emissions
requirement
All specifications are typical at nominal input, full load at 25
