1606-XLP50E — Compact DIN Rail Power Supply, 50W, 24-28V DC / 2.1A

The 1606-XLP50E is a 50W compact power supply with an extra-low-profile DIN rail housing, delivering 2.1A at 24V DC (1.8A at the upper 28V trim point) from a universal 100–240V AC or 85–375V DC input. It carries current balance capability for load sharing when units are paralleled, NEC Class 2 output classification, and certification for Class I, Division 2 hazardous locations — a combination that targets safety circuits and compact panel applications where space and certification scope both matter.

A Compact Power Supply Built for Parallel and Hazardous Locations

The extra-low-profile housing on this unit gives it a smaller footprint than standard-depth DIN rail supplies in the same power class, which matters in panels where every millimeter of depth counts — slim enclosures, retrofit panels with limited internal space, or installations adding a small dedicated safety circuit supply alongside an existing main panel power feed. NEC Class 2 classification covers a defined power limit intended to reduce shock and fire risk from the wiring it feeds, simplifying inspection requirements for low-voltage circuits in jurisdictions where that classification applies.

Current balance capability between paralleled units is a specific feature worth understanding: rather than simply wiring two supplies together and hoping for even load sharing, this supply actively balances current draw across paralleled units, extending total available current or providing redundancy without one unit carrying a disproportionate share of the load.

FAQ

Q: Can multiple 1606-XLP50E units be paralleled for higher total current?

Yes. The current balance feature is specifically designed to support this — paralleled units share load current evenly rather than one unit bearing most of the demand.

Q: Does the Class I, Division 2 rating affect the unit's standard electrical performance?

No. The core specifications — output power, current, and regulation — are unaffected by the hazardous location certification, which is an additional qualification layered onto the same design.

Q: What's the practical benefit of NEC Class 2 classification for the output circuit?

Class 2 power sources are subject to a defined power limit specifically intended to reduce shock and fire risk, which can simplify the wiring methods and protection required for circuits powered from this supply under applicable electrical code.

Q: Is screw or spring-clamp termination available on this model?

Both termination styles are offered across this product family — confirm the specific terminal type ordered against the panel's preferred wiring method before installation.
