Product Overview
The BAM series mining intrinsically safe power supply module (hereinafter referred to as the module) features current limiting, voltage limiting, and short-circuit protection functions, and can automatically resume normal operation after a fault is cleared. It is a key component of the company’s KDY series mining flameproof and intrinsically safe DC power supply.
This product must be installed and used in a safe area or within a flameproof enclosure.
The explosion-proof marking of the product is [Ex ib Mb] I.
