Current Transducer CT 5 .. 25-T
For very accurate measurements of currents : DC, AC, pulsed...,
with a galvanic isolation between the primary circuit (high power)
and the secondary circuit (electronic circuit).

Features
• Closed loop (compensated) current
transducer
• Insulated plastic case recognized
according to UL 94-V0
• Patent pending.
Advanced features
• f = 500 kHz
• X G = ± 0.1 % (- 25°C .. + 70°C).
Advantages
• Excellent accuracy
• Very good linearity
• Low temperature drift
• Optimized response time
• Wide frequency bandwidth
• No insertion losses
• High immunity to external
interference
• Current overload capability.
Applications
• AC variable speed drives and servo
motor drives
• Static converters for DC motor drives
• Battery supplied applications
• Uninterruptible Power Supplies
(UPS)
• Switched Mode Power Supplies
(SMPS)
• Power supplies for welding
applications.
Note :
1) If the short-circuit has a duration more than 1 s, the primary current of
the supply voltage must be interrupted for a short time to restore the
transducer to proper working order. The internal protection is done by
PTC resistors.
Application domain
• Industrial.
