SPS-48V
 
Input Input Voltage
48VDC
 
Inrush Current 0.20 A (peak cold start)
 
Hold-Up Time 20 msec minimum at full load and nominal input voltage
 
Isolation Voltage
(Dielectric withstand)
Meets IEC 960 for one minute.

1,500 VAC: Output/Input
500 VAC: Input/Safety GND
500 VAC: Output/Safety GND Output

 
Output Voltage
12VDC
 
Output Current
0.8A
 
Line Regulation ±0.5% of all output within specified range
 
Load Regulation
±1.0% at 20% load to full-rated load
 
Cross Regulation
±1.0% maximum on any output change from 50% to 100% rated load
 
Transient Response
Output voltage returns in less than 3 msec following a 50% load change
 
Over Load Protection: (OLP) When the average power rating exceeds 125%–150% of maximum power, output voltages reduced to a safe dissipation level; protects against short circuit of any output.
 
Over Voltage Protection: (OVP) 124% ±8% on output
 
Over Circuit Protection Withstands a continuous short without damage; returns automatically to regulation upon removal of short
 
No Load Operation No damage to power supply when operating at no load
 
Overshoot Protection No voltage spike at power-on, power-off, or power failure
 
Power Distribution +12VDC at 0.8 A maximum
 
Power Consumption 14 watts max
 
Long Term Stability 0.1% peak-to-peak of output voltage (typical)
 
Efficiency 70% (typical)
 
Noise and Ripple 1% peak-to-peak of output voltage (typical)
