Description
The model 438UF (Universal Flasher) is an all Solid State In-Line device providing ON-OFF
(flashing) control to any load device operating
from 24 to 240V AC or DC. Flash rate is set via a remote resistor ranging from zero to 10
meg ohms to achieve a flash rate ranging from 30 FPM to 1 flash every 2000 seconds. During
the "On" portion of the cycle, full load current is permitted to flow. At the
end of the ON portion of cycle 438UF turns "OFF" and permits only leakage
current to flow through the load.
Specifications
| Operating Voltage |
24-240V AC 50/60 Hz or DC |
| Timing Mode |
Flasher |
| Output |
10 mA to 0.25A inductive. Inrush to 8A for 8ms.
10 volt (max) drop across flasher output during ON period, 3mA (max) leakage current
through flasher output during OFF period. |
| Flashing Range |
2 - 2000 seconds @ 50% duty cycle. At the 2
second flash period, output is ON for 1, and OFF for 1 second. |
| Flash Rate Adjustment |
Each additional 10K across two center terminals
increase both the ON period, and the OFF period by 1 second, ON always equals OFF. |
| Flash Rate Adjustment Tolerance |
+/- 10% calculated value. |
| Operating Temperature |
-20 deg. C to +85 deg. C. |
