The 40-667C-011 is a dual 3-channel 30A MUX and is part of our range of high current multiplexers occupying two slots of PXI chassis. Each multiplexer switch uses a fully isolated solid state relay which has been designed to offer fast operation under hot switching conditions and high inrush current with no operational life degradation. Each multiplexer channel can support 10A of continuous current and switch up to 200V signals. The switches can sustain inrush currents in excess of 50A. AC or DC signals can be switched since the switch is polarity insensitive.

Polarity Tester
PT-1
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

Power Analyzers
At PCE Instruments you will find a power quality analyzer to measure the power in W, kWh or to analyze and measure harmonics. This power analyzer is a multi-function power analyzer device that measure precisely direct current, alternating current, AC-voltage, DC-voltage the intensity of DC or AC, phase rotation and idle, apparent and effective power. The reading of AC power is considered the real value and has a maximum range of 6000 Watts. While a reading is being taken, the polarity changes automatically, if negative values are taken then a minus sign will appear on the device display.Nowadays, power quality analyzers have many features such as, insulated current input, measurement of harmonics, AC and DC current measurement, AC and DC voltage measurement, frequency measurement, phase rotation measurement and idle, apparent and effective power measurement. All this data can also be logged and analyzed with the delivered PC-Software. Power analyzers of the type PCE PA 6000 can determine the energy in single-phase systems.Power quality analyzers of type PCE-GPA 62 allow the energy measurement in symmetrically loaded three-phase systems. Power analyzers of type PCE-PA 8000, PCE-360 and PCE-830 support professional power and energy measurements in single and three-phase systems.Apart from being used as energy-measuring devices, power analyzers like the PCE-830 can also be used for network analysis and the determination of harmonics and phase rotation. On our website you will find other power analyzers used in the field of electronics.
