SPECIFICATIONS

Ac Input 90-264 Vac, 47-63 Hz single phase.

Input Current Maximum input current at minimum 120 Vac, 60 Hz with full rated output load is A.

Hold-up Time 15 ms minimum from loss of ac input at full load, nominal line 115 Vac .

Output Power Normal continuous output power is 20 W, 24 W peak for 60 s maximum duration, 10% duty cycle. Factory set to begin power limiting at approximately 28 W.

Output Regulation from initial setpoint measured by changing load from 5% load to 50% load or 50% load to full load in either direction. Initial setpoint tolerance is measured at 50% load. A minimum load of 5% of the output current is required to maintain proper regulation.

Overload Protection 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 scope probe directly across output terminals of the power supply with load terminated with uF capacitor.

Transient Response Main output 750 us typical response time for return to within of final value for a 50% load step within the regulation limits of minimum and maximum load, A/us Maximum voltage deviation is Startup/ shutdown overshoot less than

Overvoltage Protection Built in with firing point set per ratings table. OVP firing reduces voltage to less than 50% of nominal voltage in 50 ms.

Turn-on time Less than 1 second at 115 Vac, 25o C inversely proportionate to input voltage and thermistor temperature.

Efficiency 70% minimum at full rated load, nominal input voltage. Efficiency increases as output voltage increases.

Input Protection Internal ac fuse provided on all units. Inrush Current

Inrush is limited by internal thermistor. The inrush at 230 Vac, averaged over the first ac half-cycle under cold start conditions will not exceed 32 A.

Temperature Coefficient 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 per °C above 50°C. See Environmental Specifications on next page.

EMI/EMC Compliance All models include built-in EMI filtering to meet the following emissions requirements:
