Features
The TDF series has been specifi cally designed
for process control applications to protect the
switched mode power supply units on devices
such as PLC controllers, SCADA systems and
motor controllers. Units are UL
®
Recognized
and available for 3A, 10A and 20A loads and
suitable for 110-120V ac/dc and 220-240Vac
circuits.
The TDF is a series connected, single phase
surge fi lter providing an aggregate surge
capacity of 50kA (8/20μs) across L-N, L-PE,
and N-PE. The low pass fi lter provides up to
65dB of attenuation to voltage transients.
Not only does this reduce the residual
let-through voltage, but it also helps
further reduce the steep voltage rate-of-rise
providing superior protection for sensitive
electronic equipment.
