AC Current Sensor
RCTi and RCTi 3ph
The RCTi & RCTrms sensors convert ac current to an isolated 0-5V voltage or 4-20mA current loop. TA5V-5A allows compatibility with existing 1A or 5A CT metering circuits. Both offer a choice of proportional (rms) and instantaneous outputs. The available RCT current ranges are 0-100A to 0-50,000Apk. Both RCTi and RCTrms provide accurate measurement over a wide bandwidth ensuring precise measurement even with harmonically distorted wave shapes - using a flexible clip-on sensing coil. The RCTs are available as single and three phase models.

Ignition Pulse Detector
IP-3000A
IP-3000A Ignition pulse detector is a slim and light weighted detector by using amorphous metals fiber element. It is 1/4 in thickness (mass: approx. 1/50) and 1/3 in weight compared with the previous model of Ono Sokki. Also the IP-3000A can obtain constant output from low to high rotation with high sensitivity.Meeting the needs of structure or mechanism in recent gasoline engines, the IP-3000A can easily clamp around an ignition coil cable (the primary side cord of ignition coil or the current cord of electronic distributor). Moreover, heat-resistant design up to maximum operating temperature of +120 C° enables measurement under harsh environment.The IP-3000A Ignition pulse detector can be used with Ono Sokki’s engine tachometer.

Series 67 & 68
Series 67 PCB mounting with switch and coil connections in a Single-in-Line format.Series 68 PCB connections on the underside for coil connections. Flying leads from the top face for high voltage connections.The Series 67 and 68 are constructed using former-less coils. The absence of a coil supporting bobbin allows a device smaller than the industry norm. The unusual package design gives some interesting possibilities for high density packing.The option of flying leads for the high voltage connections makes it possible to keep this away from lower voltage circuitry on the pcb.Form A (energize to make) contacts are available with the option of 5, 12 and 24 volt operating coils.

Circuit Breaker Test Equipment
DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.Applications supported by the DV Power test equipment include measurements of:Contact resistanceDRM (dynamic resistance measurement)Coil resistance and coil current (IEC 62271-100)Mechanism charging time (IEC 62271-100)Minimum trip voltage (IEC 56, ANSI C37.09)Undervoltage release (IEC 60694)The timing of a circuit breaker’s main, auxiliary and pre-insertion contactsSynchronization between the contactsMotion and velocity“First trip” testThe essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.

Round Wire Coil Inductors
Round wire coil (RWC) inductors come in six platform sizes and enable the highest efficiency of any SMT inductor through the use of a low loss ferrite core material which minimizes AC losses and also eliminates thermal ageing. The use of round magnetic wire instead of rectangular flat coils enables a lower cost while still maintaining a low DCR and small footprint. The platforms have passed the AEC-Q200 stress test qualification proving the designs robustness and suitability to difficult environments but the parts are not IATF certified. The platform range from 7.6×7.4×6.4mm to 26x26x15mm and are suitable for a wide range of applications and markets including communications, computing and industrial.
