Mine flameproof intrinsic safety type power box
Intrinsic safety type power box is mainly used in the coal mine with explosive gas environment, for coal mine safety monitoring system of the underground substation and various kinds of intrinsically safe mine sensors provide four road power supply. Has the function of four road power and spare batteries ;
1. Power supply: AC 127V, 220V, 380V, 660V optional input, flexible and convenient
2. Intrinsically safe outputs: four groups 18V/385mA, AC-DC converter output level signal
3. Output load and impact resistance with a strong, full load output voltage ripple ≤ 0.1V, easy to use and practical
4. Switching power supply design, high efficiency and the ability to adapt to power fluctuations
5. Four power control output, relay dry contact, to adapt to any control circuit
6. Battery-powered, full load for 2 hours or more, in general, maintain 4-5 hours
