The DR series of power supplies provides a reliable
DC power source for any industrial control system.
These economical and reliable power supplies for
industrial devices (PLCs, stepper
drives, sensors, switches) are
designed for use in harsh
industrial environments.
Combining rugged, compact
enclosures, incorporating all
international standards and
approvals, and offering short-circuit, over-load,
over-voltage, and over-temperature protection, the
DR series makes your power supply choice a simple
one. These high quality power supplies have passed
a 100% full load burn-in test, and are UL/CUL listed,
TUV/CB certified, and CE marked. Models are
available with output ratings from 75 to 240 W,
with 24 Vdc output. Customers can choose
from a full range of input voltages (85 to 264 Vac
and 120 to 370 Vdc compatible) making the
DR series unbeatable.
