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:
1.5 A
Hold-Up Time
15 ms minimum from loss of ac input at full load, nominal line (115
Vac).
Output Power
50 W continuous, 60 W peak. Peak ratings are for 60 s maximum
duration, 10% duty cycle. During peak load condition, output
regulation may exceed total regulation limits.
Overload Protection
Fully protected against short circuit and output overload. Short
circuit protection is cycling type power limit on outputs 1 & 2;
foldback type on output 3. Recovery after fault is automatic. See
output ratings chart for additional notes or conditions.
Efficiency
70-85% at full rated load, nominal input voltage, depending on
model and load distribution.
Minimum Load
Operating without minimum load will not degrade reliability, but
regulation may be affected. Multiple output models require 20%
minimum load on V1 for proper regulation. Single models require
5% minimum load.
Turn-on Time
Less than 1 second at 120 Vac, 25°C (inversely proportional to input
voltage and thermistor temperature).
Input Protection
Internal ac fuse provided. Designed to blow only if a catastrophic
failure occurs in the unit—fuse does not blow on overload or short
circuit.
Inrush Current
Inrush is limited by internal thermistors. Inrush at 240 Vac, averaged
over the first ac half-cycle under cold start conditions will not exceed
37 A.
Temperature Coefficient
0.03%/ºC 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 2.5% per °C above 50°C.
See Environmental and Packaging Specifications on next page.
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
500 µs typical 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
deviation is 3.5%. Startup/shutdown overshoot less than 3%.
Voltage Adjustment
Built-in potentiometer adjusts V1 ±5%.
Overload Protection
Factory set to begin power limiting at 60 W.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following
emissions requirements:
