Abstract

The test apparatus of the present invention tests the power supply on a military aircraft, which power supply provides power to missiles carried by the aircraft. The apparatus tests for an overvoltage condition, wherein the power supply output exceeds the maximum allowable voltage of the missiles. The test apparatus includes an electrical connector for interfacing the test apparatus with the aircraft power supply, and an electrical comparator that compares the voltages from first and second inputs. The first input is clamped to a voltage which is representative of the maximum voltage limit of the missiles and the second input is tied to the output of the aircraft power supply so as to vary with the power supply output. The comparator activates a warning lamp when the second input voltage exceeds the first input voltage to warn an operator of an overvoltage condition.
