Explosion-proof type
Electric heating explosion-proof safety power supply (referred to as heating safety power supply) is an AC220V/AC36V/42V low-voltage safety control power supply used for winter electric heating of pneumatic control systems and other equipment in drilling well sites.
By adopting safe voltage and dry-type isolation transformer technology, the power supply has the characteristics of small size, beautiful appearance, safe operation, and easy maintenance. It has the characteristics of small footprint and deep penetration into the load center in installation and use.
