Power Isolation Transformers for Safety-Critical Applications

Description

M4L Series of International Power Isolation Transformers are double-reinforced and offer OEMs the ability to streamline access to global markets while cutting the cost and shortening the process of obtaining new product safety agency approvals.

All M4L transformers are made of low-loss silicon and flame retardant polymers and rated to 4 KV hipot and successfully tested to 12 KV without breakdown.They range in weight form 7 to 22 lb and supplied in four sizes, ranging  from 4.20 x 4.08 x 3.75 in. to 4.89 x 5.70 x 5.25 in. The input voltage range is100 to 480 v.

They can be used in safety-critical applications such as fire alarms and security systems, emergency lighting, and deep mining exploration.
