The OSES & OSESL ranges of AC Voltage Stabilisers are ideal for installation outdoors, or more challenging internal environments. Fundamentally they are our SES and SESL ranges of Servo Electronic Stabilisers presented in more robust NEMA 3 style enclosures.

​

With ingress protection to IP54, OSES & OSESL enclosures ensure complete protection against contact with internal electronic or electrical components & guard against harmful deposits of dust & water splashing against the casing from any direction.

​

With all the advanced controls & protection features found in our SES & SESL ranges, OSES & OSESL stabilisers also offer as standard the availability of protection against extremely high voltage surges and transients caused by lightning strikes on the utility supply line.
