Products Introduce

1606‑XLS480E‑3 is a three-phase high-performance switching power supply of the 1606‑XLS series, 24V DC/480W (20A), with active current limiting to reduce grid impact. The front panel potentiometer is adjustable to 24-28V, and the default is 24V±0.5%. 150% overload takes approximately 4 seconds. Redundant configuration requires 1606‑XLR series redundancy modules.

FAQ:

1.How long does 150% of peak power (30A/720W) last for the 1606-XLS480E-3?

The typical duration of 150% peak power (30A/720W) for the 1606‑XLS480E‑3 is approximately 4 seconds.

2.What protection features does 1606-XLS480E-3 include?

Protection Type	Trigger Condition	Protection Action	Remarks
Output Overvoltage Protection	Approximately 32V ±10%	Switches to hiccup mode, automatic restart attempts	Redundant circuit limits maximum output voltage to prevent load damage
Output Overload/Overcurrent Protection	Exceeds rated 20A (continuous) / 30A (peak for approx. 4s)	Current limiting + hiccup mode, auto-recovery after fault clearance	Suitable for inrush loads such as motor starting and capacitor charging
Output Short-Circuit Protection	Short circuit at output terminals	Hiccup mode, automatic restart	Electronic protection, no fuse replacement required
Overheating Protection	Internal temperature exceeds safety threshold	Derating/shutdown, auto-recovery after cooling	Output power derates by 12W per 1℃ increase in ambient temperature
Input Overvoltage/Undervoltage Protection	Out of 3-phase AC 380‑480V / DC 450‑780V range	Output shutdown, auto-recovery after voltage recovery	Wide input range compatible with IT systems
Input Surge/Current Limiting Protection	Cold start or grid voltage fluctuation	Active current limiting, reduces grid impact	Inrush current <5A for 2s (cold start), protects front-end circuits
Internal Input Fuse	Severe fault on input side	Fuse blowout protection, non-user-replaceable	Ultimate overcurrent protection for main circuit

3.What are the differences in parameters/functions between 1606-XLS480E-3 and 1606-XLS240E-3 (240W)?

Parameter Item	1606‑XLS480E‑3	1606‑XLS240E‑3	Difference Description
Rated Power	480W	240W	480W model is twice the power of the 240W model
Rated Output Current	20A (24‑28VDC)	10A (24‑28VDC)	Output current of 480W model is doubled
150% Peak Power	720W (30A), lasts approx. 4‑5 seconds	360W (15A), lasts approx. 4‑5 seconds	Same peak duration, only magnitude difference
Input Type	3‑phase AC 380‑480V / DC 450‑780V	3‑phase AC 380‑480V / DC 450‑780V	Identical input voltage range
Derating Coefficient	12W/°C	6W/°C	480W model has double the derating rate due to higher heat dissipation demand
Physical Dimensions (W×H×D)	Approx. 84mm×124mm×102mm	Approx. 48mm×124mm×102mm	480W model is 75% wider, occupying more DIN rail space
Weight	Approx. 1.2kg	Approx. 0.8kg	480W model is 50% heavier
Inrush Current	<5A (2s cold start)	<2.5A (2s cold start)	Inrush current of 480W model increases proportionally
DC‑OK Dry Contact	Standard configuration	Standard configuration	Identical function and contact capacity
Protection Functions	Full protection: overvoltage/overload/short‑circuit/overheating/input abnormality	Same as left	Identical protection logic and proportional thresholds
PFC Type	Active PFC, typical power factor 0.94	Same as left	Identical power factor characteristics
Efficiency	Up to 92%	Up to 92%	Identical efficiency curve; 480W performs better under high load
