DVC1000-P
LEM DVC1000-P PCB voltage transducer, 1000 V nominal with ±1500 V range, +5 V supply and a direct low-voltage output.
The DVC1000-P is a LEM printed-circuit-board voltage transducer that measures DC, AC and pulsed voltage up to 1000 V nominal with a measuring range of about ±1500 V, using LEM's insulation digital technology. It combines isolated high-voltage measurement with a single +5 V supply and a low-voltage analog output of about 3.833 V at the nominal primary voltage, so it connects directly to a microcontroller ADC without an external measuring resistor. The transducer provides galvanic isolation between the high-voltage primary and the low-voltage secondary, protecting the control electronics and improving safety, and it offers low offset, low sensitivity error and excellent overall accuracy with a fast rise time. The compact PCB format suits modern high-density boards where a panel-mount transducer will not fit, and the single-supply operation simplifies the power architecture. Typical uses include DC-link voltage monitoring in motor drives and solar inverters, battery and traction voltage sensing in electric vehicles, and rail monitoring in power supplies and UPS systems. The wide -40 °C to +85 °C operating range covers industrial and outdoor equipment. Every DVC1000-P BeiLuo ships is a genuine LEM part, factory-traceable and supplied with an import declaration, a certificate of origin and a RoHS compliance file, together with our FAE support for layout, isolation and output scaling. Its combination of high-voltage isolation, single-supply operation and direct voltage output makes it a practical choice for compact, high-voltage control boards.
FAE Professional Review
The DVC1000-P is the transducer we recommend when a compact board must measure a 1000 V DC link with a single +5 V rail and a direct ADC output. It removes the external measuring resistor that a current-output part would need. Follow the recommended isolation clearances carefully, because the primary sits at high potential while the secondary stays low voltage.

Frequently Asked Questions
Why choose the DVC1000-P over a current-output transducer?
The DVC1000-P provides a direct low-voltage output from a single +5 V supply, so it needs no external measuring resistor and no bipolar rail. That simplifies a compact, high-voltage control board.
Choose a current-output part when you need to run the signal over long wiring.
How do I scale the output for my ADC?
The output is about 3.833 V at the nominal primary voltage, so you scale it in firmware or with a simple divider to match your ADC range. The reference output lets you compensate for supply variation.
Our FAE team can confirm the scaling for your ADC.
Is the part genuine and in stock?
