VM10
The VM10 isolated amplifier is designed for measuring DC voltages in power distribution systems, particularly for public transport networks. It ensures high voltage isolation for safety.
Main Features
- Wide supply voltage range: 24 to 230 VDC ± 20% and 24 to 230 VAC ± 10%.
- Low non-linearity error and high immunity.
- High galvanic isolation up to 15 kV.
- Compact design suitable for various applications.
Technical Specifications
- Input voltage ranges from 0.75 to 3 kV, with both unipolar and bipolar options.
- Output voltage is Us nom ± 5 V, with output current options of Is nom ± 20 mA or Is 4 ... 20 mA.
- Maximum load resistance (RLmax) is 600 ohms.
- Error on gain and non-linearity is less than ± 0.3%.
- Cut-off frequency is greater than 5 kHz.
- Voltage consumption is less than 5 VA, with residual ripple under 10 mVeff.
- Operating temperature range is -25 to +85 °C.
Standards and Compliance
- Galvanic isolation complies with EN50124-1, with 3-port isolation between input, output, and power supply.
- EMC standards include EN50121-5 and EN61326 class B.
Mechanical Data
- Dimensions: 90 x 67.5 x 118 mm (H, W, D).
- Weight: 500 grams.
- Sealing: IP 40 (Housing).
- Mounting: DIN rail.
Applications
The VM10 amplifier is suitable for applications requiring voltage measurement with high isolation, such as in Voltage Limiting Device (VLD) applications.
