AC Current Probes
Powertek's AC current probes and sensors cover single-phase and three-phase current monitoring across industrial automation, energy metering, and power electronics. The range includes flexible Rogowski coil probes with voltage and current loop outputs (0.333 V, 5 V, 1 A, 5 A), split-core Hall Effect transducers for DC-coupled measurements, and rugged IP54-rated probes for harsh environments. Measurement ranges span sub-ampere signals to tens of thousands of amperes, with frequency responses from DC to several kilohertz. Standard output options include 4–20 mA, 0–10 V, and true RMS signals, ensuring direct compatibility with PLCs, DAQ systems, and energy management controllers.

Transducers
Powertek transducers convert AC and DC electrical quantities—voltage, current, active power, and frequency—into isolated analogue signals for integration with PLCs, SCADA systems, and data acquisition hardware. The range includes single-phase and three-phase voltage transducers (VTH, VTHR), current transducers (ATH), watt and power transducers, true RMS converters, summation transducers, and 4–20 mA loop isolators. DIN-rail mounting is standard across most models; many also offer Modbus/RS485 connectivity. Input ranges are configurable, with isolated 0–10 V or 4–20 mA outputs as standard. Suitable for energy monitoring, motor drives, variable frequency drives, utilities, and building management systems.

Calibrators
Powertek's multifunction calibrators generate precision AC and DC voltage, current, power, and energy reference signals for the calibration and verification of electrical instrumentation. The range spans portable process calibrators for field use (MC9000 series), bench-top power and energy calibrators (MC9010, MC9010+), three-phase power energy calibrators (MC133c-3f), and high-current transconductance amplifiers (MC151, 0–120 A). Additional models cover RTD simulation, programmable resistance decades, and thermocouple simulation. Accuracy levels range from parts-per-thousand to 10 ppm, making the range applicable to secondary standards laboratories, calibration service facilities, and production test benches.

Coaxial Current Shunts
Powertek's co-axial current shunts—also known as current viewing resistors (CVRs)—are precision non-inductive resistors designed for wideband current measurement in high-frequency power electronics test applications. The co-axial geometry eliminates parasitic inductance, enabling accurate current waveform capture from DC to tens of megahertz. The range includes socketed, in-line, PCB-mounting (SDN series), and high-power flat-format (Series W) variants, rated from a few watts to several hundred watts. Series A, F, K, L, M, R, SDN, and W configurations address a broad spread of impedance, power rating, and mechanical requirements, including stud, clamp, bar-strap, and flange input styles.

DC Current Probes
Powertek's CTH range of DC current probes and sensors uses closed-loop Hall Effect technology to measure direct currents without electrical contact with the conductor under test. Split-core and non-split construction options enable both retrofit installation on live busbars and PCB-level sensing. Models cover measurement ranges from sub-ampere signals to 40,000 A, with isolated voltage and 4–20 mA loop outputs. Specialist derivatives include the DCflex flexible-coil DC probe for very large busbars, the CTH-GIC for geomagnetically induced current monitoring in power networks, and the ISCTH intrinsically safe variant certified for hazardous area use.

Differential Voltage Probes
Powertek's differential voltage probes provide safe, high-bandwidth voltage measurement with galvanic isolation from the circuit under test. They are designed for use with oscilloscopes and data acquisition systems where grounding constraints prevent the use of conventional probes on floating or high-voltage nodes. The range spans low-voltage, high-sensitivity models (DP-02VF, 80 Vp-p, 150 MHz) to very high voltage probes (DP-40K, 40 kVp-p; DP-22kpro, 22 kVpk). Frequency bandwidths extend from DC to 150 MHz. All models present a differential input pair that rejects common-mode voltages, producing a single-ended output at standard oscilloscope-compatible levels.

High Frequency Current Probes
Powertek's CWT series are Rogowski coil AC current probes engineered for wideband current measurement in power electronics, motor drives, and EMC testing. Flexible clip-around construction allows rapid, non-invasive installation without circuit interruption. Standard CWT and CWTHF models cover 0.1 Hz to 30 MHz with di/dt ratings to 5,000 MA/s. Ultra-miniature variants (CWTUM, CWTUM-S, CWTUM-F) with cross sections as small as 1.2 mm are suited for measurement between the legs of SiC and GaN power semiconductors. The CMC probe variant addresses common-mode shaft current measurement for bearing erosion diagnosis in motor drive systems.

Phase Angle Voltmeters
Powertek's phase angle instrumentation covers phase-sensitive voltage measurement, frequency response analysis, and phase/amplitude ratio measurement for calibration, sensor characterisation, and control loop testing. The PAV1010A phase angle voltmeter measures total Vrms, in-phase and quadrature components, and the phase angle between two voltage inputs—well suited to LVDT, resolver, and synchro testing. The SD1000 phase meter provides direct digital readout of phase angle. The GP1700 frequency response analyser generates Bode plots and Nyquist diagrams, allowing stability margin characterisation of power supplies, servo loops, and filter networks from sub-Hz to 15 MHz.

Power Analyzers
Powertek's power analyzers and wattmeters measure AC and DC power, energy, power factor, harmonics, and total harmonic distortion across single-phase and three-phase power systems. The PXe-PA900 series offers wideband simultaneous multi-channel measurement for motor testing, inverter evaluation, and power quality analysis. Portable wattmeters (PA110, PA120) and compact DIN-rail transducers (WT3ph, Ptk-P series, UPC) address field measurement and integrated monitoring. Network analysers (PTK-UPA20, PTK-UPA30) and programmable kilowatt-hour meters (PTK-UEC6C) extend the range into utility tariff metering and building energy management.

Static Frequency Converters
Powertek's PXe static frequency converters (SFCs) provide regulated single- and three-phase AC power at selectable output frequencies—typically 50 Hz, 60 Hz, or 400 Hz for avionic applications—from a standard mains supply. Solid-state IGBT-based conversion eliminates the mechanical wear inherent in rotary motor-generator sets and delivers clean output waveforms for testing aircraft electrical systems, marine equipment, and frequency-sensitive apparatus. The range covers 1 kVA to 60 kVA, with single-phase input/three-phase output, three-phase in/out, and rack-mounting configurations. Programmable output voltage and frequency allow use as a general-purpose AC power source for product testing and compliance work.
