Temperature Coefficient

0.03% / °C typical.

EMI/EM Compliance

All models include built-in EMI filtering to meet the following EMC requirements of

IEC601-1-2.

Ac Input

90-264 Vac, 47-63 Hz single phase. Class I or class II grounding.

Input Current

Maximum input current at 90 Vac, 60 Hz with full rated output load not to

exceed 0.6 A.

Input Protection

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

failure occurs in the unit -- Fuse does not blow on unsustained overload or

short circuit.

Inrush Current

Inrush is limited by internal thermistors. The inrush at 240 Vac, averaged over

the first ac half-cycle under cold start conditions will not exceed 37 A.

Efficiency

69-85% depending on model.

Overload Protection

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

tion is cycling type power limit. Factory set to begin power limiting at 23 W.

Overvoltage Protection

Built in OVP on all models. Approximately 120-140% of output voltage.

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 - 500 µs max. response time for return to within 0.5% of final

value for a 50% load step change, ∆i/ ∆t< 0.2 A/μs. Maximum voltage devia-

tion is 3.5%.

Hold-up Time

10 ms minimum from loss of ac input voltage at full load, nominal line (120

Vac).
