NOTE:
20MHz bandwidth ripple & noise is measured by using 0.1uF C.C. & 10uF/50V E.C. bypassed at the output connector.
3)PROTECTION:
3.1)
OVER VOLTAGE PROTECTION:
If any over voltage occurs, the power supply should latch off before any output exceeds its limit below:
NOMINAL
VOLTAGE(V)
+12
FROM
13
OVERVOLTAGE RANGE(V)
TO
15
The power supply will not be automatically recovered after the over voltage fault being removed. A manual
power reset is necessary.
3.2)
SHORT CIRCUIT PROTECTION
Any short circuit occurred on any DC output should not cause any damage to the power supply,
but will shut down the power supply. The power supply will not be automatically recovered after
the short circuit being removed. A manual power reset is necessary.

3.3)
OVERLOAD PROTECTION
An over load protection will be effected when overloading reaches +160% MAX.
The power supply will not be automatically recovered after the overload being removed.
A manual power reset is necessary.
3.4)
VIBRATION:
10-55Hz amplitude (sweep 1 min.) less than 2G X, Y, Z 1 hour ea.
3.5)
SHOCK: <20G
