Overview
The Allen‑Bradley 1606-XL120D is a 120 W power supply for industrial control applications with high efficiency and wide‑range input.
Input Specifications
-
Input voltage: AC 100...120/200...240V (switchable), 47...63 Hz (85...132V AC / 176...264V AC, 210...375V DC). With switch in 230V position, operates at low/moderate loads (to 3A) from 95 to 264V AC. At DC input, always leave switch in 230V position.
-
Input current: < 2.6 A (115V position); < 1.4 A (230V position).
-
DCin at open output: typ. 5 mA.
-
Inrush current: typ. 15 A at 264V AC (cold start).
-
Fuse recommendation: 10 A slow‑acting fuse (HBC) or 1492‑SPU1C100 recommended.
-
EN 61000‑3‑2 (harmonic current emissions) fulfilled.
-
Transient handling: 750V / 1.3 ms per VDE 0160/W2.
-
Hold‑up time: > 37 ms at 196V AC, 24V/5 A.
Output Specifications
-
Output voltage: 24V DC +5% –1% (24...28V DC on request).
-
Output noise suppression: EMI below EN 50081‑1, even with long unscreened cables.
-
Voltage regulation: better than 2% overall.
-
Ripple / Noise: < 50 mVPP (20 MHz, 50 Ω).
-
Overvoltage protection: typ. 29V.
-
Parallel operation: yes; current sharing on request.
-
Power back immunity: 26V.
-
Front panel indicator: Green LED; goes out at Vout < 18V.
Efficiency, Reliability & Lifecycle
-
Efficiency: typ. 90% (230V AC, 24V/5 A).
-
Losses: typ. 13.3 W (230V AC, 24V/5 A).
-
MTBF: 520,000 h per SN 29500 (24V/5 A, 230V AC, Tamb = +40°C).
-
Electrolytics: long‑life type rated for +105°C.
Start / Overload Behavior
-
Start‑up delay: typ. 0.1 s.
-
Rise time: approx. 5...20 ms (load‑dependent).
-
Overload: no disconnection or hiccup; current limited with gradual Vout reduction; high overload current up to 1.9 INom.
-
Power boost: 6A short‑term (or continuous at 45°C / forced cooling).
-
Advantages: high short‑circuit current for reliable start with difficult loads; no fold‑back sticking; secondary fuses operate reliably.
Temperature & Derating
-
Ambient temperature (operation): –10°C...+70°C (>60°C derating).
-
Storage: –25°C...+85°C.
-
Derating: typ. 3 W/K from +60°C to +70°C.
