Topstek THD3A
Topstek Current Transducer THD3A .. THD51.6A
THD 3A~51.6A
Features
Highly reliable Hall Effect device
Compact and light weight
Fast response time
Excellent linearity of the output voltage over a wide input range
Excellent frequency response (> 50 kHz)
Low power consumption (12 mA nominal)
Capable of measuring both DC and AC, both pulsed and mixed
High isolation voltage between the measuring circuit and the
current-carrying conductor (AC2.5KV)
Extended operating temperature range
Flame-Retardant plastic case and silicone encapsulate, using
UL classified materials, ensures protection against
environmental contaminants and vibration over a wide
temperature and humidity range
Applications
UPS systems
Industrial robots
NC tooling machines
Elevator controllers
Process control devices
AC and DC servo systems
Motor speed controller
Electrical vehicle controllers
Inverter-controlled welding machines
General and special purpose inverters
Power supply for laser processing machines
Controller for traction equipment e.g. electric trains
Other automatic control systems
