Introduction

The explosion-proof charger is suitable for the underground charging chamber containing methane and coal dust with risk of explosion and danger, which is used for charging the batteries of the special explosion-proof storage battery locomotive in the coal mine with the environment of explosion danger and risk for methane and coal dust in mine.

Explosion-proof charger adopts micro-electronic automatic control technology, when charging, just set the charging current, when the charging current increases and decreases, this machine automatically adjust according to the current and voltage you set, its no need to adjust the voltage at regular intervals, no need to phase conversion, when the battery polarity is reversed, output short circuit, overload, this machine will automatically disconnect the charging circuit.When problem is solved,charger automatically switch into the working state; The machine output DC voltage, current will be display in digital mode.

Features:

1: Small Size, light weight, easy operation and maintenance.Input voltage:380V,400V,415V,480V.600VAC

2: The AC part and the control part, which are easy to produce sparks, constitute the flameproof cavity respectively, so as to make the control part work stably. 3: The use of digital module control, high precision, stable output.

4: With steady current characteristics, suitable for constant current charging.

5: With overload, open phase and short-circuit protection.

6: no need to adjust phase sequence.

7: With the initial charging function, charging current can be adjusted.
