PHOTOTRANSISTOR SENSOR
SOLID STATE PHOTOCONTROLS
"Optimum Performance Without Operational Drift"
|
| DESCRIPTION
P Series electronic photocontrols utilize a phototransistor light sensor. The photo sensor holds its original operating parameters throughout its life. It is not susceptible to operational "drift" caused by cadmium sulfide breakdown caused by harsh environments or breakdown caused by over heating ( a condition of AC electro-mechanical designs). Extended life is achieved through a non-chatter load break from a low power consumption DC circuit. |
FEATURES
* Meets or exceeds ANSI C136.10.
* Proven DC circuit design.
* Close 1:1.5 On to Off operating ratio.
* Non-chatter load break.
* Electronic phototransistor light sensor maintains
operational levels throughout its life.
* Heavy duty construction.
|
BENEFITS
* 12 year expected life.
* Low power consumption and extended life
from "cool" operating DC circuit.
* Close ratio reduces burning hours at sunrise.
* Reduced burning from consistent operating levels
throughout its life.
* Significantly reduced energy costs.
* Significantly reduced maintenance costs.
