Product Description
The Allen-Bradley 1606-XLP30B is a 30-Watt, single-phase switched-mode power supply (SMPS) from the XLP series, designed for industrial applications and capable of acting as a backup power source. It accepts 100-240VAC input, rectifies and filters it, and uses a high-frequency DC-to-DC converter to provide an adjustable 10-12VDC output. Features include screw/spring clamp terminals, startup load boosting, a minimum 18ms hold-up time, DIN rail mounting, and an internal input fuse. The IP20-rated plastic housing with ventilation grids on three sides relies on convection cooling, requiring 25mm clearance around the ventilation grids. It offers 750V transient immunity (1.2ms) and 84% efficiency.
Is Your Device Showing These Signs?
The Allen Bradley 1606-XLP30B power supply commonly experiences issues such as output voltage instability due to capacitor degradation, resulting in under-voltage faults and equipment malfunction. Troubleshooting often reveals problems with the internal components of the power supply, specifically the electrolytic capacitors drying out, causing ripple voltage and impacting the DC output. Rectification diode failures and transformer winding shorts are also frequent causes of power supply failure. Resolving these issues typically involves replacing faulty capacitors, diodes, or the entire power supply unit to restore stable and reliable power delivery.

Our Repair Process for the
1606-XLP30B
Our repair process for the Allen Bradley 1606-XLP30B power supply begins with a thorough diagnostic assessment to pinpoint the root cause of the malfunction, focusing on common failure points such as capacitor degradation, diode failures, and transformer winding shorts. We meticulously inspect internal components, paying close attention to electrolytic capacitors for signs of drying out or ripple voltage issues affecting the DC output. Upon identifying the faulty component, we proceed with its replacement, utilizing high-quality replacements to ensure optimal performance and longevity. If component-level repair is not feasible or cost-effective, we replace the entire power supply unit with a new or refurbished unit that meets or exceeds original specifications. Post-repair, rigorous testing is conducted to verify stable and reliable power delivery, guaranteeing the equipment functions as intended.
