Applications

AC Input:
Wide range input from 90-264VAC

DC Outputs:

See Voltage/Current Rating Charts

Output Power:

See Voltage/Current Rating Charts.

Brown-Out Voltage:
Regulation is maintained with full rated load at 90VAC .

Hold-Up Time:
20 msec typical at full rated load and nominal AC input
voltage. Hold-up time increases to 40 msec at 50% load.

Efficiency:
Measured at full rated load and nominal AC input voltage.
75% ±5% depending on how the load is distributed among
the outputs.

Regulation Characteristics:
See Voltage/Current Rating Charts for individual model ratings.
Measurement method:
Line: Measured over a 90-132VAC or 175-264VAC
line change.
Load: Measured over a 20% to 100% load change. Multiple output model regulation is subject to the minimum load requirements.

Initial Setting Tolerance:
Measured at 50% of full rated load on all outputs.

Input Protection:
AC input line fuse provided. Internally located.

Output Noise and Ripple:
0.3% RMS, 1% PK-PK Typical.
 

Overload Protection:
Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition. Delayed-fold back current limiting characteristic assures reliable turn-on into reactive and non-linear loads.

Power-Up Initialization Period:
Typical 2.0 sec turn-on delay assures orderly ramp-up and stabilization of all output voltages during power-up.

Overvoltage Protection:
Clamp, 130-150%.

Temperature Rating:
Operating: 0°C to +50°C at full rated output power. Derate linearly to 50% of full load from 50°C to 70°C.
Storage: -55°C to +85°C.

Temperature Coefficient:
±0.03%/°C typical, ±0.05%/°C maximum over entire operating temperature range of 0°C to +70°C.

Shock:
Operating: 20G peak acceleration.  

Cooling:
Convection cooling is adequate for convection power ratings providing that non-restricted convection air movement is available. When operating in a confined area, forced air cooling is recommended.

Vibration:
Random vibration from 10Hz to 2KHz, 6.15 grms (3 axis).

Safety Agency Certifications: (pending)

  • UL 1950 without D3 deviation, file #E181899
  • CSA C22.2 No. 950, UL file #E181899
  • CE Marked
