ALS-600SPS Switching Power Supply
ALS-600SPS Voltage Settings
When opening up the ALS-600SPS make sure it is unplugged and has been off for a
while to make sure the capacitors have been discharged. Some of the capacitors can
have a charge of 300-400VDC.
The ALS-600SPS will only need to be changed when switching between 120 and
240VAC. Move these jumpers only when changing voltages. Do not move any other
wires or bayonet connectors in the power supply.
