SPECIFICATION |
| Load
Regulation |
the
output voltage load regulation is less than the values in the
following table by changing each output load ¡Ó40% from 60% rated
load, and keep other outputs at 60% rated load.
Output # 1. ¡Ó3%
2. ¡Ó5% 3.
¡Ó2%
4. ¡Ó2% 5.
¡Ó2% 6. ¡Ó3% |
| Line
Regulation |
The
line regulation for each outputs is less than ¡Ó1% while measuring
at rated load with ¡Ó10% if 115V/AC or 230V/AC input voltage
changing. |
| Ripple
an Noise |
The
peak to peak ripple and noise for +5V, +3.3V output are less than
50mV, and for the other outputs are less than 100mV at rated load.
Measuring is done by 15MHz band width limited oscilloscope and
terminated each output with a 0.47uF capacitor. |
| Efficiency |
The
efficiency is higher than 73% while measuring at nominal line and
rated load. |
| Holdup
Time |
The
holdup time is longer than 20mS at 115V/AC. |
| Protection |
-
Over Voltage Protection: For some reasons the power supply might
fail to control itself, the build-in crowbar circuit will
automatically shut down the outputs to avoid damaging the external
circuits. The trip point of O.V.P. circuit is around 5.7V to
7.0V
- Short Circuit Protection: The power supply will go into
hiccup mode function against short circuit or over load conditions.
If the fault condition removed, the power supply will restart
automatically.
- Power Good/ Fail Signal: When power is turned on, the power
good signal will go high between 100ms to 500ms after all output DC
voltages are within regulation limits. While the power fail
signal will go lo at least 1ms before any of the output voltages fall
below the regulation limits.
- Power ON Signal: This TTL compatible signal (active low) is
use to switch ON the main output. When power on is disconnected
form secondary common, all outputs except +5VSB
shall turn off.
- Operation Temperature: 0¢XC to 70¢XC (when the ambient
temperature is over 40¢XC (15V/230V), the output power should be
derated as following curve) |
