FAQ
Q: Is 1606-XL480EPT still available?
A: Officially discontinued on October 30, 2017. We supply tested surplus and refurbished units. Direct replacement is 1606-XLE480EP.
Q: How do I set the output voltage?
A: Use the covered front-panel potentiometer. Range is 24…28 V DC. Confirm with a meter before connecting loads.
Q: Can it run on 120 V and 230 V mains?
A: Yes. Auto-select input covers AC 100…120 V and 200…240 V, 47…63 Hz. Continuous range is 85…132 V / 184…264 V.
Q: Which replacement should I choose?
A: For new designs use 1606-XLE480EP. For existing legacy panels, keep 1606-XL480EPT if form-fit-function and rail space must stay unchanged.
Q: What should I check before ordering surplus units?
A: Confirm hold-up time needs (30 ms at 24 V/20 A), verify derating above +60 °C, and check that no communication interface is required. This unit has no ports.
