Input
Surge
34 amps peak from cold start for units under
400 watts, 68 amps for other models.
Efficiency
75% typical.
Holdup
Time
20 milliseconds after loss of nominal AC power.
Outputs
See model selection table. Outputs are trim adjustable
±5%.
Output
Polarity
All outputs are floating from chassis and each
other and can be referenced to each other or ground as required.
Line
Regulation
Less than ±0.1% or ±5mV for input
changes from nominal to min. or max. rated values.
Load
Regulation
±0.2% or ±10mV for load changes
from 50% to 0% or 100% of max. rated values.
Minimum
Load
Main output requires a 10% minimum load for full
output from auxiliaries. Use Option 08 if no minimum load
is available. Singles requires no minimum load.
Ripple
& Noise
1% or 100 mV, pk.-pk., 20 MHz bandwidth.
Operating
temperature
0-70°C. Derate 2.5%/°C above 50°C.
Cooling
A min. of 6 LFS* for models under 400 watts,
10 LFS for others, directed over the unit for full rating.
Two test locations on chassis rated for max. temperature
of 90°C. For convection ratings consult factory.
*Linear feet/second.
Temperature
Coefficient
±0.02%/°C.
Dynamic
Response
Peak transient less than ±2% or ±100
mV for a step load change from 75% to 50% or 100% max. Outputs
recover within 300 microseconds.
Safety
Units meet UL 1950/60950, CSA 22.2 No. 60950-00,
EN 60 950, IEC 950.
Dielectric
Withstand
3000 VRMS input to ground.
3000 VRMS input to output.
700 VDC output to ground.
Spacing
5 mm primary to secondary, 2.5 mm to ground.

Leakage
Current
0.75 mA at 115 VAC, 60 Hz. input.
Input
Undervoltage
Protects against damage from under voltage
operation.
Soft
Start
Units
have soft start feature to protect critical components.
Overvoltage
Protection
Standard on all outputs. Latching action.
Reverse
Voltage Protection
All outputs are protected up to load ratings.
Overload
& Short Circuit
All outputs are protected by foldback current
limiting with automatic recovery.
Thermal
Shutdown
Circuit cuts off supply in case of local over
temperature. Units reset automatically when temperature
returns to normal.
Fan
Output
Nominal 12 VDC @ 12 watts maximum.
Inhibit
TTL compatible system inhibit provided.
Remote
Sensing
On all outputs greater than 75 watts.
