Omni L1A-DC — Speed control for DC fans

martFan Omni L1A is a medium power DC

control designed to be used with 12 or 24

VDC fans with power ratings up to 38

Watts. It operates in a linear mode applying a

smooth DC voltage to the fans for minimum

noise. Omni L1A is available for both Closed-

Loop (temperature regulating) and Open-Loop

(temperature compensating) applications. It

includes a temperature alarm, triggered if the

sensor temperature reaches 10°C above the

Control Temperature. Omni L1A is compatible

with sensors P1 through P9 shown on page 34.
