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:

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:
