PRODUCT DETAILS
1606-XLE480EPC — 480W DIN Rail Power Supply with Power Factor Correction, Conformal Coated, 24V DC / 20A
The 1606-XLE480EPC is a 480W, 20A power supply combining active power factor correction with conformal-coated circuit boards in one unit. It accepts 100–240V AC or 110–150V DC input and delivers a regulated 24V DC output adjustable up to 28V. The "P" in the catalog number indicates the power factor correction circuit; the "C" indicates the conformal coating — two features bundled together for installations that need both clean input current draw and protection against humidity or contamination.

Power Factor Correction Plus Conformal Coating
Standard switched-mode supplies without power factor correction draw current in pulses that don't track the input voltage waveform closely, producing a lower power factor — typically in the 0.5–0.6 range. Active PFC, as implemented on this unit, shapes the input current to track the voltage waveform much more closely, raising the power factor toward unity. This matters in facilities where harmonic distortion limits, utility power factor penalties, or shared-transformer loading with many switched-mode supplies make low-power-factor equipment a real operational concern.
Layering the conformal coating onto this PFC-equipped model extends its service life in environments with condensation, dust, or mild chemical exposure that would otherwise accelerate board degradation. The combination is specifically useful for facilities needing both clean input current draw and environmental robustness from the same supply, rather than choosing one feature at the expense of the other.
FAQ
Q: Does power factor correction affect the supply's output regulation or ripple performance?
No. PFC operates on the input stage, shaping AC current draw — it doesn't change the output voltage regulation or ripple specifications, which remain consistent with the non-PFC variant in the same family.
Q: Can this supply operate from a DC input source instead of AC?
Yes, within the specified 110–150V DC input range, in addition to its AC input capability.
Q: Is the conformal coating visible or does it change the unit's external appearance?
The coating is applied internally to the circuit boards, not the exterior housing — externally the unit looks the same as the non-coated variant in the same family.
Q: Can two of these supplies be paralleled for higher current or redundancy?
Parallel operation for redundancy is supported on this power supply family using the appropriate redundancy module — verify wiring and voltage trim settings against the manufacturer's parallel operation guidance.
