 SHA-1250-ITS
120VAC / 1 Phase / Modular
The SHA-1250-ITS is an upgraded version
of the SHA-1210.
The SHA-1250-ITS 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-ITS 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-ITS is specifically designed
for both type 170 and NEMA Traffic controller cabinets.
The performance level is similar to the popular
SHA-1210.
The unit consists of three basic sub- circuits. These are
primary clamp, the secondary clamp, and the filter.
