The Aimtec AMEL20-3.3SAZ is a 20 Watt AC-DC converter designed for ITE (Commercial) applications. It operates with an input voltage range of 90-305 VAC at 47-440 Hz, and a DC input range of 130-430 VDC.
This converter provides a single output of 3.3V with a maximum current of 4A. Key electrical specifications include a typical efficiency of 73% at 115 VAC, ±2% voltage accuracy, ±1% line regulation, and ±2% load regulation. It also features a maximum capacitive load of 5600 µF and a ripple & noise level of 200 mV p-p.
Designed for reliability, the AMEL20-3.3SAZ has an operating temperature range of -40°C to +80°C (with derating) and a MTBF of over 400,000 hours. The unit offers I/O isolation of 3000 VAC and includes over-load and over-voltage protection.
The converter is housed in a compact 5-DIP module package with Through Hole mounting. Its dimensions are 56.5mm x 30.9mm x 25.1mm, and it weighs 70g. The case material is plastic, rated to UL 94V-0.
The input voltage range is 90-305 VAC (AC) or 130-430 VDC (DC).
The output voltage is 3.3V and the maximum output current is 4A, providing up to 20W.
The operating temperature range is -40°C to +80°C with derating.
It comes in a 5-DIP module with 4 leads, through-hole mounting.
It includes overload protection (foldback at 110% for AMEL20-5SAZ, 130% for others), over voltage protection (Zener diode clamp), and short circuit protection with auto recovery.
Typical efficiency is 73% at 115 VAC and 230 VAC, and 72% at 277 VAC.
The dimensions are 56.5mm (length) x 30.9mm (width) x 25.1mm (height), weight 70g.
