PMK PHVS663-L-RO high-frequency 250M high-voltage 2800 Vrms/6 kVpk oscilloscope voltage probe (1000:1)

The PHV Series of Probes extend the measuring range of your oscilloscope to safely and easily probe high voltages. Applications include power supplies and UPS devices, frequency converters and electrical inverters in powertrain engineering, semiconductor relays, and IGBTs. Our high voltage probes are suitable for observing the fastest signal and waveform events, such as standard pulses in EMC testing or glitches you want to detect.

A high-voltage probe is a front end that can measure high-voltage DC, high-voltage AC, and high-voltage pulses and, after attenuating the electrical signal by a certain ratio, output it to an oscilloscope, multimeter, or recorder for display. When selecting a high-voltage probe, the prerequisite is that the probe itself meets the safety standards for high voltage and extra-high voltage; in addition, it must have the corresponding voltage overload capability and be able to reproduce the measured waveform without distortion.

Key features:

1. Bandwidth up to 400 MHz: meeting high-frequency challenges

The PMKpassive probePHV66x series and PHVS66x have a maximum bandwidth of up to 400MHz, a feature that makes them perform excellently in high-frequency signal detection. Whether it is high-frequency current measurement in power systems or high-frequency signal analysis in industrial equipment, this probe can provide stable responses. Its wide bandwidth not only ensures measurement accuracy but also effectively prevents high-frequency interference from affecting the measurement results.

2. Flexible cable length: adapts to various installation requirements

The PMKpassive probePHVS66x series offers the conventional cable length options of 2m-5m, while the PHV66x provides more flexible cable length choices, ranging from 1.2 meters to 5 meters. This design further enhances the probe installation flexibility, allowing users to select the appropriate cable length according to actual needs. Whether for short-distance measurements or long-distance transmission, users can adjust the cable length flexibly based on specific circumstances, without the need for additional cable modifications or complex wiring work.

3. 50 MΩinput impedance and good input capacitance

The input impedance and capacitor parameters of probe directly affect the quality of signal transmission. Both the PMKpassive probePHV66x series and PHVS66x series use a 50MΩ input impedance design, which can effectively reduce charge discharge and reflection, ensuring stable signal transmission. At the same time, the input capacitance of the PHV66x series is 7.5pF, and the input capacitance of the PHVS66x series is 6–8pF; after precise calibration, they can form good impedance matching with cables of different lengths and probe, thereby reducing signal distortion and interference. This design allows probe to maintain high accuracy measurements even in long cables or complex environments.

4. peak value Voltage can reach 6kV: Suitable for high-voltage environments

Compared with the PHV series, the PMKpassive probePHV66x series and PHVS66x series can both handle a maximum input voltage of up to 6kV. This enhancement makes their measurement capabilities more outstanding in high-voltage environments. In scenarios such as power systems, high-voltage equipment manufacturing, and electronic device testing, this probe can meet higher voltage measurement requirements. Its high voltage withstand capability not only ensures measurement safety but also prevents measurement errors caused by voltage fluctuations or transient changes.

5. probe The design is basically consistent with the PHV series

The PMKpassive probePHV66x series and PHVS66x series are basically designed the same as the PHV series. Their slender front-end design can easily adapt to narrow space environments. Whether it is complex internal structures of equipment or measurements in confined spaces, this probe can respond flexibly. Its slender probe head design not only ensures measurement accuracy, but also reduces interference with the surrounding environment, ensuring the reliability of measurement results.

6. Various accessories available: suitable for a variety of measurement environments

To meet the needs of different scenarios, the PMKpassive probePHV66x series and PHVS66x series both offer a variety of accessories, allowing users to choose and combine them according to actual requirements. For example, cables of different lengths, adapters, connectors, etc., can meet the requirements for long-distance measurements, measurements at different voltage levels, and installations in complex environments. This flexibility enables the probe to perform excellently in various fields such as power systems, industrial equipment, and electronic devices.

7. Accuracy ±2%: ensuring measurement accuracy

The PMKpassive probePHV66x series and PHVS66x series measurementsaccuracy are both ±2%, a level that has already reached a high standard in industrial measurement and power engineering. Their precise measurement performance can help users accurately assess the operating status of equipment and ensure the safe operation of systems. Whether it is current measurement, voltage detection, or signal analysis, thisprobe can provide reliable data support.

The PHV66x/PHVS66x series can be considered an extension of the PHV series. The product appearance is similar, but the voltage tolerance is higher, providing customers with more options, and it also meets the market demand for higher voltages.

In addition, the PHV66x and PHVS66x can be said to come from the same family test parameters and are basically identical, with the two probe differing in transformation ratio. This difference in transformation ratio means that the PHVS66x series has a larger measurement range, suitable for scenarios requiring the measurement of higher voltages, but its sensitivity is lower. The PHV66x series, on the other hand, has a lower transformation ratio, a higher sensitivity, and is suitable for measuring signals within a medium voltage range. Users can choose the appropriate probe according to their needs.
