0.5% within 500 μs.

Ac Input

85-264 Vac, 47-63 Hz single phase.

Input Current

Maximum input current at 120 Vac, 60 Hz with full rated output load is 0.85 A.

Hold-up Time

15 ms minimum from loss of ac input at full load, nominal line (120 Vac).

Output Power

Normal continuous output power is 28 W, 32 W peak for 60 s maximum dura-

tion, 10% duty cycle. Factory set to begin power limiting at approximately 35

Overload Protection

Fully protected against short circuit and output overload. Short circuit pro-

tection is cycling type power limit.

Output Noise

0.5% 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 0.1 μF capacitor.

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.

Voltage Adjustment

Factory set with fixed resistors to maximize reliability.

Efficiency

70% minimum for the 5.1 V model at full rated load, nominal input voltage.

Efficiency increases as output voltage increases.

Input Protection

Internal ac fuse provided on all units. Designed to open only if a catastrophic

failure occurs in the unit.

Inrush Current

Inrush 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.
