SKF® hybrid bearings with silicon nitride rolling elements and steel rings provide insulation against stray currents in large variable speed electric motors to eliminate electric arc bearing damage and resulting premature bearing failure. The ceramic rolling elements further make these bearings lighter, harder … (read more)

Bipolar transistors, having 2 junctions, are 3 terminal semiconductor devices. The three terminals of a bipolar transistor are emitter, collector, and base. The transistor can either be a NPN transistor or PNP transistor. (read more)

The Model 173 AC Current Monitor is a single setpoint AC current monitor. It can be used to detect either over current or under current, depending on whether the set point is set above or below the input current. (read more)

Current Sensing Relays provide an effective and highly stable method for monitoring electrical current. Current Transducers and Transmitters are for AC or DC Voltage & Current Voltage, Current, Power, Power Factor, Energy and Frequency can all be monitored in a single package. The sensed information is then provided to the system via an RS485 serial bus. (read more)

Precision, low inductance shunts for DC and AC current metrology

The A40B Precision Current Shunt Set consists of 14 low-inductance coaxial current shunts, adapters and connectors, and a rugged transit/storage case. (read more)

The Model 2744 3-Phase Over Current Monitor is designed to monitor the current level of a three-phase line or to compare the currents of three single-phase lines.

If one or more current inputs rises above the trip level after the start delay has expired, the internal relay will de-energize.

Start delay of 5 to 15 seconds and adjustable trip point from 1 to 5 amps. (read more)

The Current Measurement Card is a highly accurate DC current measurement system designed to convert the current and voltages provided by system Power Supplies into voltages measurable by Intepro 9000 PSU Test Systems. (read more)
