About this file
The document is a product specification sheet for the SHA-1250 Transient Voltage Surge Suppression device manufactured by EDCO (Emerson Network Power), located in Ocala, Florida. This technical data sheet details a traffic signaling product designed for type 170 and NEMA traffic controller cabinets, specifically targeted at state and local transportation infrastructure applications.
The SHA-1250 is a 120VAC/1 Phase modular surge protection device with advanced features including remote sensing circuitry, LED failure indicators, and a dry relay contact closure for remote monitoring. Key technical specifications include a peak current rating of 20,000 Amps, a response time of less than 5 nanoseconds, and an operating temperature range of -40°C to +85°C. The device offers noise suppression across a broad frequency range, with typical attenuation of 10db @ 10 KHz, 50db @ 100 KHz, and 90db @ 1 MHz. The product is designed for easy installation with a hardwire terminal base (SHA-1250-BASE-A) that is compatible with older traffic controller cabinet configurations, allowing for straightforward retrofitting.

SHA-1250
120VAC / 1 Phase / Modular
The SHA-1250 is an upgraded version of the SHA-1210IRS. The two models are equal in surge protection performance. 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.
The chart below illustrates typical filtering characteristics. 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 ACP-340. The unit consists of four basic sub-circuits. These are primary clamp, the secondary clamp, the filter, and the remote sensing and indicator circuitry.
CAUTION
This product could become excessively hot and rupture in the rare event of power line conditions or surge that exceed its rated operating specification. Appropriate precautions should be exercised.
High voltages are present on electrical termination. Unit should be serviced by qualified personnel only.
