  • Dytronic Primary Transfer Ultra Stable Standard

    RD-22 Ultra - Radian Research, Inc.

    The RD-22 Dytronic Primary Transfer Ultra Stable Standard represents the state-of-the-art technology in a commercially available AC transfer reference. The Ultra Stable RD-22 is a variant of the RD-22 Primary Transfer Standard that has been optimized for 120/240 V @ 5A operation to provide optimum stability. In a stable test environment, repeatability for a 10-second test of ±0.6 µWh/VAh is attained at 120 V and 240 V at 5A inputs with a 95% confidence interval. A typical experimental 2 repeatability of less than ±0.25 µWh/VAh is achieved. In a stable test environment, a reproducibility of ±2 µWh/VAh over a five-day interval is attained at 120 V and 240 V at 5A inputs with 95% confidence interval.

  • Energized Cable Sensor

    Hubbell Power Systems Inc

    The purpose of the Energized Cable Sensor is to allow the lineman to readily determine whether a URD cable is energized. The sensor consists of an amplifier which is designed to give a meter reading when the small AC voltage between the semi-conductive sheath and the concentric neutral of the energized URD cable is applied to the test probe. The amplifier is housed in a rugged phenolic case. Sensor may be used to check for energized condition on concentric-neutral cable below an elbow without test points. At cable mid-span (left), hose clamps bridge all strands of concentric neutral at the test location. Sensor’s neutral lead clips to one of the hose clamps. Tip on probe lead contacts only semi-conductive cable sheath to test for voltage presence.

  • Round Wire Coil Inductors

    Pulse Electronics

    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.

  • Saturable Reactor Inductors

    Osborne Transformer Corp.

    Osborne Saturable Reactors are designed to provide a variable output voltage through the use of variable impedance connected in series with a constant impedance load. Each saturable reactor’s impedance is determined by the application of DC power to a control winding. As the level of power supplied to the control winding is increased, the saturable reactor becomes more saturated. This reduces the impedance of the AC gate winding, and increase the amount of the supply voltage that is transferred to the load. Conversely, as the power is reduced to the control winding, the reactor becomes less saturated, the gate winding has more impedance and less of the input voltage is provided to the output impedance. This approach provides excellent quality, reliability, and control when designed to match the requirements of a specific application.

  • AWD Dynamometers

    MD-AWD-500-AC/EC-100/250 - Mustang Dynamometer

    The key to designing an AWD dynamometer properly is to understand the methods currently being used by manufacturers in the field of AWD drivetrain technology. A dynamometer that can accommodate various types of AWD vehicle transmissions and wheelbases without excessive complication and, more importantly, without risking damage to a client’s AWD system is paramount. Full time AWD vehicles are designed to provide maximum performance regardless of road conditions. In cases where traction is less than ideal, a vehicle may be designed to improve stability and traction at the expense of power. This means adding torque to a spinning wheel or retarding of timing. In order to properly test an AWD vehicle for peak performance, an AWD chassis dynamometer must be able to simulate ideal road-load conditions to the vehicle. This approach allows the vehicle to be evaluated under “optimum” operational conditions; whereby torque is distributed to the vehicle’s tires in the same manner that would normally occur when a vehicle has equal traction at all four drive wheels, and is therefore operating at peak efficiency. To achieve this, Mustang’s AWD-500 Series incorporates an internal drive system that synchronizes the front and back rollers to simulate a flat, dry road condition. Synchronization, or linkage, insures that the front and rear rollers are always spinning at precisely the same road speed. This process eliminates the possibility of activating a vehicle’s traction control system and also insures that a vehicle’s torque management system is operating under the assumption that the vehicle is not skidding, turning or slipping. Mustang’s AWD-500 can be operated in AWD Mode while testing two-wheel drive vehicles. This process allows the non-driven axle to be spun by the dynamometer rollers at the same speed as the driven axle, eliminating the speed differential that occurs on two-wheel drive dynamometers – problem solved.

  • Trifield Meter

    100XE - Alpha Lab, Inc.

    The Trifield Meter is a gaussmeter, electric field meter, radio field strength meter in a single unit. When measuring electromagnetic fields (EMFs), the primary concern is usually magnetic fields, which can be tricky to measure. If a less sophisticated 1-axis gaussmeter is used, a reading of zero could result even where the field is strong. A 1-axis meter must be oriented correctly to measure the field (which is a vector). The 3-axis Trifield Meter solves that problem by measuring the true strength of the field regardless of which way it is oriented. Therefore, the Trifield Meter can be scanned rapidly across an area without having to stop at each point to search for the orientation that gives a maximum reading. Another section of the meter detects AC electric fields, which can exist independently of AC magnetic field. The third section detects radio/microwave, such as from a leaky microwave oven.
