Simulated Mk-344 Loads
3.4.7 Output Voltage Under Constant Load at Extreme Limits of A-C Operating
Power Inputs -
3.4.7.1 Repeat 3.4.6.1 and 3.4.6.2 with the operating power inputs specified
in 3.4.5.1 a, b, c, and d. The magnitude of the output voltage shall not vary more
than + 0.5 volts from the voltages of 3.4.5.1 and 3.4.5.2.
3.4.8 Short Circuit at Standard Operating Power Input -
3.4.8.1 With the Fuze Function Control switch in the VT position, the power
supply output shall be subjected to a 2 ohm + 10 percent short circuit for a
duration of 5 + 1 seconds. After removal ofthe short, the output voltage shall be
--
within +0.5 volt of the output voltage prior to the application of the short circuit.
3.4.8.2 With the Fuze Function Control switch in the INST position, repeat
3.4.8.1. After removal of the short, the output shall be within + 0.5 volt of the
output voltage prior to the application of the short circuit.
3.4.9 Short Circuit at Extreme Limits of A-C Operating Power Inputs -
3.4.9.1 Repeat 3.4.8.1 and 3.4.8.2 with the operating power inputs specified
in 3.4.5.1 a, b, c, and d.
-
3.4.10 Voltage Drift at Standard Operating Power Input -
3.4.10.1 VT Position - With power supply at room temperature and standard
I
operating power input applied, the Fuze Function Control switch shall be switched
to the VT position. The open circuit output voltage shall not drift more than
+1.50 volts d-c within 30 minutes after turn-on. Voltage readings shall be taken
