Signal Transformer / Bel M4L More-4-LESS™ International Transformers
Signal Transformer / Bel M4L More-4-LESS™ International Transformers are lightweight chassis-mount transformers that support high ambient temperatures. The M4L transformers feature 4kV dielectric strength, 300VA to 1000VA power ratings, 115V output voltage, 30µA leakage current, and UL 94V-0 flame rating. These transformers provide a 12mm creepage distance between the input and output windings. Typical applications include medical beds, C-arm tables, ultrasonic atomizers, home oxygen therapy equipment, dental chairs, veterinary tables, MRI machines, cancer eradication equipment, and nurse call stations.Features
