LXinstruments GmbH
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.

Bernstein AG
In general, inductive proximity switches consist of four basic elements: a coil, an oscillator, a threshold switch and an output stage with short-circuit protection.The oscillator generates a high frequency, electromagnetic alternating field which is emitted from the active face of the coil.Eddy currents are induced in a metal object that enters this field. These eddy currents draw energy from both the electromagnetic field and from the oscillator which is consequently attenuated.The more energy taken the closer the metal object moves towards the active face. The threshold switch switches on the output stage at a defined attenuation value.In proximity switches with a DC voltage supply, this switch is designed as an NPN transistor which switches the connected load to the negative pole or as a PNP transistor which switches the load to the positive pole. The output stage is a thyristor or a triac in AC voltage switches.

Series MSK -
Kepco, Inc.
Kepco's MSK linear power supplies provide a selection of five models, offering 100 Watts of stable benchtop power. They use a high gain linear (series pass) stabilizer circuit for ultra low noise and low ripple output, good stability, and accurate resettability, and they are MIL-STD-461 compliant.MSK's "Preview" switch (d-c on-off) allows voltage and current to be pre-set with the digital meters displaying the set values. At "d-c off," no voltage is applied to the output terminals and no load current needs to be drawn to set the current limit. At "d-c on," the set voltage is applied to the output terminals, the appropriate mode indicator illuminates and the meters indicate actual voltage and current.

XCBS-DL -
Green Switch Innovations
The XCBS-DL is permanently wired into each crossing warning system, and can be configured with either a removable or non-removable bypass key. Simply connect the track connection harness to the designated track connection terminals. To prevent unnecessary operation of the crossing warning system, insert the key and select "bypass", rotate the knife switch to "bypass" and the crossing is disabled. When in the "bypass" position, a Dummy Track Load is connected to the track wire connections in parallel with the rails and the crossing approaches are shorted, preventing unnecessary activation when track equipment is working in the crossing approach circuit. The opening of one track lead may be desired to prevent unnecessary activation with intermittent shunting on the crossing approaches close to the crossing.

Series HSM -
Kepco, Inc.
The Kepco HSM series comprises a group of ten models, seven 1000 watt power supplies with outputs from 3.3 volts to 125 volts and three 1500 watt power supplies with outputs from 24 to 125 volts. All models feature current sharing for parallel operation and redundancy applications. Kepco¹s 1000W HSM have a wide-range input (90-277V a-c). The 1500W models operate 180-277V a-c. Both incorporate power factor correction to meet EN 60555-2 and EN 61000-3-2. These modern power supplies operate at 100KHz using current mode control to provide rapid response to source and load changes and tight stabilization.
