Edco SHA 1250/SHA-1250-BASE-A
120 VAC Single Phase Modular Filter with Base
The Edco SHA-1250 is an upgraded version of the Edco SHA-1210IRS. The two
models are equal in surge protection performance. The Edco SHA-1250 also
incorporates two LEDs for failure indicator in a modular package (utilizes 12-pin
Beau connector). The hardwire terminal base (Edco SHA-1250-BASE-A, ordered
separately) accommodates all wiring and the protection module is designed for
easy replacement.
The footprint of the Edco SHA-1250-BASE-A is the same as the Edco ACP-340 and
Edco SHA-1210. This makes retrotting older cabinets easy because internal wire
lengths do not have to be adjusted.
The Edco 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 Edco
SHA-1250 at the intersection.
The Edco SHA-1250 provides excellent noise suppression over a large frequency
range. Typical noise attenuation is 10db at 10kHz, 50db at 100kHz and 90db at 1MHz.
