OVP
(Over-Voltage Protector)
|

|
Requests for a compact, explosion-proof protection device led
to the design of the Over Voltage Protector (OVP). With the
input of potential users and our existing base of clients, the
OVP was designed and tested to meet the requirements for Class
I, Division 1 & 2, Group B, C, D classified locations. Independent
testing and product listing was performed by Underwriter’s Laboratories
(UL), authorizing the use of the UL and C-UL (Canada) marks.
The device has also been tested and approved by UL/Demko for
compliance to the ATEX directive for Zone 2 applications, and
carries the CE mark for Zone 2.
The OVP is unlike other "arrester" type products. Instead of
a gapped design, the OVP uses solid-state switching components
to conduct at very low voltages, providing the best over-voltage
protection. Rated for AC fault current as well as high values
of lightning surge current, the OVP can be applied to sites
where a spark-gap arrester or metal oxide varistor would be
inappropriate. The OVP is a totally unique product for the corrosion
prevention industry.
Note: the OVP is not recommended
where steady-state AC voltage exists between the connection
points, typically induced
AC voltage.
Features and Characteristics
- The only fail-safe "arrester" on the market (i.e. fails
shorted)
- Solid-state design eliminates arcing
- Conduction at much lower voltages than gapped arresters
- Rated for AC fault current and lightning surge current
- Suitable for submersed or above-ground locations
- UL, C-UL listed explosion-proof design
- Corrosion resistant nickel finish |
