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:

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.
GENERAL SPECIFICATION
This specification describes the performance
characteristics of a grounded, single
phase54 Watts, 2 output level adapter power
supply with +12V, -12V and remote control
