 SHA-1250
120VAC / 1 Phase / Modular
The SHA-1250 is an upgraded version
of the SHA-1210IRS.
The SHA-1250 also incorporates two
LEDs for failure indicator in a modular package (Utilizes 12 pin Beau
connector). The hardwire terminal base (SHA-1250-BASE-A,
ordered separately) accommodates all wiring and the protection module
is designed for easy replacement. The footprint of the SHA-1250-BASE-A
is the same as the ACP-340 and SHA-1210. This makes retrofitting older
cabinets easy because internal wire lengths do not have to be adjusted.
The SHA-1250 offers remote sensing
circuitry output that is a dry relay contact closure suitable to interface
with a modem or computer port for polling remotely. With this feature,
a central computer could detect a failed SHA-1250
at the intersection.
The SHA-1250 provides excellent
noise suppression over a large frequency range.
Typical noise attenuation
is 10db @ 10 KHz, 50db @ 100 KHz and 90db @ 1 MHz.
| FEATURES |
| The SHA-1250 is specifically designed
for both type 170 and NEMA Traffic controller cabinets.
The performance level is similar to the popular
SHA-1210IRS.
The unit consists of four basic sub-circuits. These are
primary clamp, the secondary clamp, the filter, and the
remote sensing and indicator circuitry.
