July 20, 2015 - Teledyne LeCroy (CEO: Woonjae Lee, http://teledynelecroy.co.kr) today announced two additions to its HVD3000 series of high voltage differential probes, the HVD3206 (2kV safety-rated) and HVD3605 (8.4 kV safety-rated). These probes demonstrate Teledyne LeCroy's leadership in the rapidly growing power electronics market by delivering superior performance and compliance with the latest industry test standards. Like the existing HVD310x probes (1kV safety-rated), these new probes offer exceptional performance, including leading gain accuracy, wide differential voltage range, wide offset range, and excellent common-mode rejection ratio (CMRR).

The HVD3605 is the ideal probe for measuring 5kV class electrical equipment and power electronics systems, with a safety rating of 8485V (DC+pk AC) and a measurement capability of 6000Vrms. It features 1% gain accuracy, excellent CMRR, and a 6m cable, along with the industry's widest differential voltage range of 7000V (DC+pk AC) and a maximum measurable differential voltage before amplifier saturation of 7600V. It also offers 100MHz bandwidth and the industry's widest offset range of up to 6000V. The HVD36005 is the only 4160 V instrument rated probe capable of probing AC Line, DC bus, and motor drive/inverter output voltages.

The HVD3206 is the world's first safety-rated 2000 V (DC+peak AC) probe and a 1500 Vds probe compliant with the IEC/EN61010-031:2015 standard. This probe is specifically designed to meet the requirements of solar string inverters requiring a 1500 Vdc input. High DC input voltages will become common in utility-scale string inverters because they allow more PV modules to be connected to each string, reducing size and cost. Teledyne LeCroy is the first company to offer a high-voltage differential probe suited for this application. The HVD3206 offers the same 1% gain accuracy, 2000 Vpk differential voltage range, 120 MHz bandwidth, and CMRR performance as the 1 kV safety-rated HVD3106 probe.

Additionally, this new product launch introduces “no accessory” (-NOACC) versions of the existing HVD3102 and HVD3106 probe models. The HVD3102-NOACC and HVD3106-NOACC are provided as alternatives for customers who require a 1 kV safety-rated high-voltage differential probe but do not require the full range of tip accessories. They are ideal for users who already have the required tip accessories or who do not require accessory tip sets but are price-conscious.

The HVD probe connects to the oscilloscope via the ProBus interface. The ProBus interface supplies the probe with the power it needs through the oscilloscope, eliminating the need for a separate power supply or battery. Changing the gain range (V/div) on the oscilloscope automatically adjusts the probe's attenuation, and you can remove any offset that may occur in the probe by directly selecting Auto Zero on the probe from the oscilloscope channel menu.
