VM12
VM12
The VM12 amplifier is designed for measuring DC voltages in power distribution systems, specifically for public transport networks. It provides high voltage isolation to ensure safety for both equipment and personnel.
- Two standard models available: 0.9 kV (SG829062P00001) and 1.8 kV (SG829062P00002).
- Supply voltage: 24 VDC ± 20%.
- Input voltage: 0.9, 1.8 kV bipolar with fixed setting.
- Output voltage: Us nom ± 5 V.
- Error on gain and non-linearity: Less than ± 0.3%.
- Cut off frequency (-3 dB): > 5 kHz.
- Voltage consumption: < 5 VA.
- Residual ripple: < 10 mVeff.
- Low non-linearity error.
- Very high immunity.
- High galvanic isolation.
- Compact solution.
- Galvanic isolation: EN50124-1, 3-port isolation between input, output, and power supply.
- Operating temperature: -25 to +85 °C.
- Galvanic isolation, input against output: 10 kVAC 50 Hz 1 min.
- EMC standards: EN50121-5 (when mounted in a cubicle), EN61326 class B (standard for isolators).
- Dimensions: 90 x 45 x 118 mm (H, W, D).
- Weight: ~ 500 gr.
- Sealing: IP 40 (Housing).
- Mounting: DIN rail.
The VM12 amplifier is suitable for use in environments requiring high voltage isolation and precise DC voltage measurement, particularly in public transport power distribution systems.
