110 WATT GLOBAL PERFORMANCE SWITCHERS
FEATURES:
All specications are typical at nominal input, full load at 25
O
C unless otherwise stated
EMI/EMC Compliance
All models include built-in EMI ltering to meet the EMC requirements below.
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, dierential 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 nal 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.

SPECIFICATIONS
Inrush Current
Inrush 240 Vac is less than 37 A, averaged over the rst 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 Coecient
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 Specications on the next page.
Commercial Safety Approvals
All models are approved to UL1950, CSA22.2 No. 950-95, IEC950, EN60950. CB
