CRITEC TDF
|
The CRITEC TDF Surge
Filters are 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 available
for 3A, 10A and 20A loads and in a range of clamping voltages 150V
and 275V.
The range is intended for use in conjunction with
CRITEC Universal Transient Barriers (UTBs) to provide a coordinated
approach to protection of both the power and data control circuits.
The space efficient low pass filter, provides up to 62dB
of attenuation to voltage transients, to further reduce the steep
rates of voltage and current rise, providing superior protection
for sensitive electronic equipment.
Features:
• Compact design fits into most distribution panels
and motor control centers
• High efficiency
sine wave filtering - ideal for the protection of switched mode
power supplies
• 35mm DIN rail mount
• Fail-safe LED indication and opto-isolated output
for remote status monitoring
• High surge rating
50kA ensures long service life
• UL 1449 ,
UL 1283 and CSA 22.2 recognized, C-Tick, CE approved
• Transient Discriminating technology ensures safe
operation during abnormal over-voltage events
Applications:
• Power surge and transient protection for sensitive
electrical and electronic loads
• PLCs
• SCADA
• Motor Controllers
• RTUs
• Protection of sub-circuits or specific
equipment which may be downstream remote from point-of-entry protection
• Protection for rail and transit signal and
communication systems
