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.
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:

C. Floating fourth output can be referenced as either positive or negative. Connect pin 12 to Return to provide a positive voltage at Pin 13. Connect pin 13 to Return to
provide a negative voltage at Pin 12.
D. To maintain these regulations conditions, the +5V current must be at least 1/5 of V2 and not greater than 5 times the V2 current. Requires +5V to be adjusted to within
1% with at least a 1 A load to maintain regulation on this output.
