18V 1.5A AC-DC Power Supply - 2.1mm x 5.5mm Center Positive | SW-1813AR
Regulated 18V 1.5A AC-DC Switching Power Supply | Part SW-1813AR
Part SW-1813AR is a dependable, wall-mount regulated switching power supply designed to convert 100–240V AC input into a steady 18V DC output at up to 1500mA (1.5A, 27W max). Featuring a standard 2.1mm inner diameter x 5.5mm outer diameter center-positive barrel plug, this adapter provides clean, stable power for compatible electronics, test benches, control monitors, and specialized industrial equipment.
Selection Note: Always select your replacement power supply based on your equipment manufacturer's documented electrical requirements rather than physical appearance or generic device categories.

Compatible Applications & Replacement Guidelines
This adapter is engineered for equipment requiring an 18V DC input, a maximum current draw of 1.5A or less, and a center-positive 2.1mm x 5.5mm connection. Common conditional applications include replacement power for certain portable instrumentation control boxes, specialized electronics, and inspection system monitors (such as select drain and pipe inspection camera control consoles), provided the manufacturer specifications precisely match.
Important Compatibility Warning: Do not use this supply with equipment requiring 12V, 12.6V, 13.5V, 24V, AC output, or center-negative polarity. Ensure you check your device's input jack rather than assuming compatibility based on accessory attachments or camera heads.
Before You Order Checklist
- Verify your device specifies 18V DC (not AC voltage or a different DC tier).
- Confirm current requirements do not exceed 1.5A (1500mA). This 1.5A supply safely powers devices requiring lower amperage (e.g., 1A, 1.2A, 1.33A) as long as voltage and polarity match.
- Confirm center-positive polarity configuration.
- Measure your plug inner diameter (2.1mm ID vs 2.5mm ID) and barrel length to ensure correct mechanical fit.
Frequently Asked Questions
Will Part SW-1813AR work with my specific equipment model?
It will work only if your device documentation specifies 18V DC, 1.5A max, center-positive polarity, and a 2.1mm x 5.5mm barrel plug. Always check the power input label on your monitor or control box.
Can this replace an 18V 1A or 18V 1.2A adapter?
Yes. A regulated switching power supply rated at 1.5A can safely supply lower current requirements if voltage, polarity, and connector dimensions match identically.
Is this a battery charger?
No. This is a regulated DC power supply, not a standalone battery charger. Do not connect it directly to unmanaged battery packs.
