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 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 ratings. 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 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 500uSec typical response time for return to within of final value for a 50% load step change, Maximum voltage deviation is

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 V to OVP point 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 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 < 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:
