  • RF Amplifiers Bias Controllers

    Analog Devices Inc.

    RF amplifier bias controllers generate a regulated drain voltage and actively adjusts the gate voltage of an external amplifier to achieve constant bias current. It can be used to bias any enhancement and depletion type amplifier operating in Class-A regime with drain voltages (VDRAIN) as specified. These devices achieve excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures used to prevent RF performance degradation due to such variations.

  • Three-Phase Transformer Turns Ratio Testers

    TRT series - IBEKO Power AB

    The TRT is a true three-phase, fully automatic test set, specially designed for a turns ratio, a phase shift, and an excitation current measurement of power, distribution, and instrument transformers. The TRT determines the transformer turns ratio by accurately measuring voltages across the unloaded transformer windings. As a test result it displays the ratio of these voltages. This ratio of voltages can also be automatically rescaled to match the physical ratio of a number of turns on a transformer high and low voltage side.

  • Coil Testers & Power Supplies

    POB Series - IBEKO Power AB

    Coil testers and power supply units, models POB30 and POB40 are ideal for commissioning and maintenance testing of circuit breakers. The station supply is not available.

In addition to providing current and voltage for breaker testing, they can measure certain coil parameters.

  • Circuit Breaker Analyzers & Timers

    IBEKO Power AB

    Circuit Breaker Analyzer & Timer (CAT) series are standalone or PC controlled digital instruments for circuit breakers’ condition assessment. They enable simultaneous measurements of up to 12 main contacts (4 breaks per a phase) including pre-insertion resistors and 6 auxiliary contacts. CAT series instruments record graphs of both, the open and close coil currents and displacements of the HV and MV circuit breaker moving parts. The main contact channels can also measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).

  • Battery Charger

    BAC25A - IBEKO Power AB

    Battery charger BAC25A is a portable universal battery charger. It can be used for charging Lead-Acid and Ni-Cd batteries. BAC25A is intended to support the main charger in order to charge battery much faster. They can also be used to quickly recharge a battery following a discharge test . Using two charging modes it provides the safely regulation of charging procedure. As a result achieving both fast recharge and low risk of overcharge. This device generates current up to 25 A.

  • Tap Changer Analyzer & Winding Ohmmeters

    RMO-T Series - IBEKO Power AB

    The Tap Changer Analyzers & Winding Ohmmeters RMO-T series are designed for winding resistance measurement of inductive objects, and for a tap changer analysis. The RMO-T instruments are based on the state of the art technology, using the most advanced switch mode technology available today. The RMO-T instruments are accurate (0,1%), powerful (up to 100 A) and lightweight (7,5 – 15,5 kg). They generate a true DC ripple free current with automatically regulated measurement and discharging circuit.

  • Hot Wire Ignition Tester

    SCR ELEKTRONIKS

    The HWI test indicates a materials resistance to ignition when exposed to abnormally high temperatures resulting from a component failure such as a conductor carrying far more than its rated current. HWI performance is expressed as the mean number of seconds required to ignite a specimen when wrapped with an energized non-chrome resistive wire that dissipates a specified level of energy.

  • High Temperature Operating Life

    7000 Series - Reltech Limited

    With ever decreasing geometries, the way we perform HTOL requires careful consideration. In lower geometry device leakage currents are not only higher but vary greatly. Temperature control at DUT level – required to achieve correct junction temperature at every DUT. For higher geometries, HTOL can be performed in a more traditional way but with devices consuming more power, the ambient temperatures required varies greatly. Multiple temperature zones are required – multi zones system or multiple smaller HTOL systems.
