Power supply status lights

When lit, the power supply status light indicates that it is providing -48Vdc power to
the Stinger CR unit. You can use the test points to measure the -48Vdc output and
verify that it is within tolerance (±10%).
The status lights for both the ±190Vdc power supply and the -48Vdc power supply
are identical. The STATUS light is lit if the power supply is providing internal -48Vdc
power for the unit.
The Stinger CR ±190Vdc power supply is shown in Figure 3-35.
