AcuAMP ACTH series AC current transducers combine a current transformer and a signal conditioner in one unit. These fixed-core transducers are available with selectable sensing ranges up to 50 Amps, and provide an analog output signal compatible with most control systems. The adaptive true RMS measurement is ideal for monitoring pulsed waveforms, such as from electric heaters.
Monitoring the current controlled by silicon-controlled rectifiers (SCRs) can be a challenge, especially the current used by heaters. Zero-crossing burst fired controls allow current to flow to the circuit for as short of a time period as one cycle, and off for several cycles. Most current sensors will not work well when there is no current present. When used to monitor zero-crossing burst fired SCRs, the ACTH series uses an innovative time integration adaptive true RMS measurement method that will provide an output signal directly proportional to the RMS amperage even when the SCR controller is providing power in one cycle increments.
