75 Watt Multiple Output Global Performance Switchers
SPECIFICATIONS
Ac Input
90-264 Vac, 47-63 Hz single phase.
Input Current
Maximum input current at 120 Vac, 60 Hz with full rated output load not to
exceed 2.3 A.
Output Power
Normal continuous output power is 75 W for unrestricted natural convection
cooling or 110 W with 26 cfm airflow. During peak load conditions output
regulation may exceed total regulation and noise limits.
Output Regulation
Measured by ±40% load change from 60% rated load with all other outputs
at 60% rated load and input voltage change from minimum to maximum rat-
ings. Output #1 requires 1A minimum load for proper regulation of other
outputs. Initial set tolerance is measured with all outputs at 60% of full rated
load. Output #2 requires 0.5A minimum load for proper regulation.
Overload Protection
Factory set to begin power limiting at approximately 120 W. Fully protected
against short circuit and output overload. Short circuit protection is cycling
type power limit.
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: 500μSec typical response time for return to within 0.5% of final
value for a 50% load step change, ∆i/∆t<0.2A/μSec. Maximum voltage devia-
tion is 3.5%.
Overvoltage Protection
Built in on V1 with firing point set per table. OVP firing reduces output #1 and
#2 to less than 50% of nominal voltage in 50 ms.
Voltage Adjust
Factory set on standard unit; however, optional potentiometer (“-V” suffix)
adjusts voltage from 4.7 V to OVP point (6.2 V nominal) on the +5 V output.
Note: Output #1 must not be more than 1% below nominal to achieve full
output voltage range on Output #2. Output regulation limits in some models
may be exceeded when the main output is adjusted beyond +1% of nominal
voltage. High voltage settings may degrade the reliability of the unit due to
excessive power dissipation in some outputs.
Class B (Commercial models) and CISPR 11 Class B
(Medical models)
EN60950-1 approvals
CSA22.2 No. 601.1-M90, and IEC/EN60601-1
All specifications are typical at nominal input, full load at 25
FEATURES:
O
C unless otherwise stated
Efficiency
68% -78% depending on model and load distribution.
Input Protection
Internal ac fuse provided on all units. Designed to blow only if a catastrophic
failure occurs in the unit.
Inrush Current
Inrush limited by internal thermistors. Inrush at 240 Vac, averaged over the first ac
half-cycle under cold start conditions will not exceed 37 A.
Hold Up Time
20 ms minimum from loss of ac input power at full load, nominal line (120 Vac).
Temperature Coefficient
0.03%/°C typical on all outputs.
Power Fail
A standard TTL or CMOS compatible output goes low (< 0.5 V) 5ms before output
voltage drops more than 4% below nominal voltage upon loss of ac power. Signal
is factory set to trip on 84 to 94 Vac brown-out depending upon incoming line
impedance and distortion. Other settings are available through adjustment of
built-in potentiometer (consult factory for assistance). Output will stay low for 20
ms minimum.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions requirements:
