Brief Introduction

The battery powered electromagnetic converter is equipped with a lithium battery as its standard configuration, which can work consecutively three years. If a high-capacity battery is equipped, the continuous working time will be much longer.

Designed with IP68-level seal protection for its die-cast aluminum case, the battery powered electromagnetic converter is particularly applicable for damp environment, for example, underground mine and burial installation, etc.
