Varistor Products

High Energy Industrial

DA/DB Varistor Series

The DA and DB Series transient surge suppressors are heavy-duty

industrial metal-oxide varistors designed to provide surge protection for

motor controls and power supplies used in oil-drilling, mining, and trans-

portation equipment.

These UL-recognized varistors have identical ratings and specifications

but differ in case construction to provide flexibility in equipment designs.

DA series devices feature rigid terminals to insure secure wire contacts.

Both the DA and DB series feature improved creep and strike distance

capability to minimize breakdown along the package surface design that

provides complete electrical isolation of the disc subassembly.

See DA/DB Series Device Ratings and Specifications table for part

number and brand information.

Power Dissipation Ratings

100

Should transients occur in rapid succession, the average power dissipa-

tion required is simply the energy (watt- seconds) per pulse times the

number of pulses per second. The power so developed must be within the

specifications shown on the Device Ratings and Specifications table for

the specific device. Furthermore, the operating values need to be derated

at high temperatures as shown in Figure 1. Because varistors can only

dissipate a relatively small amount of average power they are, therefore,

not suitable for repetitive applications that involve substantial amounts of

average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of V

(at specified current) of more than ±10% could result.This type of shift, which normally results in a decrease of V ,

N(DC)

may result in the device not meeting the original published specifications, but it does not prevent the device from continuing to function, and to provide ample protection.
