With a host of features to improve
reliability and efficiency, the 78 Series
of switched mode power supplies
from Finder gives control system
builders a stable and dependable low
voltage DC supply. Said to be 91%
efficient, and drawing only 0.4W in
standby, the modular, rail mounted
DC power supplies come in 24VDC,
36W; 24VDC 60W and 12VDC, 50W
output variants that support universal
AC or DC supply ranges, respectively
100-265VAC and 140-370VDC.

The 78 Series includes: thermal
protection with fast output voltage
shutdown; short circuit protection
with ‘hiccup’ (auto-recovery) mode
and overvoltage (varistor) protection.

In addition, the power supplies’ high
inrush current handling capability
means they safely tolerate loads with
high current transient characteristics,
such as capacitive circuits and
solenoids with ‘economy’ resistors.
