These units have extended filtering characteristics and are suitable for use in high noise environments. Use of high-energy surge protection devices give low residual voltage values even under extreme conditions.

Available in different plug standards and variation in number of sockets, each unit has an integral circuit breaker and fault indicator. The professional range is equipped with a thermal disconnect device which disconnects the high capacity metal oxide varistors from the mains of over-stressed due to frequent high energy surges or long over voltage conditions. If the thermal disconnect triggers, it will also automatically disconnect the power as a further precaution. The professional 2000 has increased filtration and full indication.
