Overview
The Vimar VM01970 is a DIN rail power supply that converts 12 to 24 V AC or DC onboard power to a 29 V DC supply for a By-me Plus bus system.
Total output current is up to 800 mA and the unit provides separate 29 V BUS and 29 V AUX outputs, with a decoupling coil on the BUS output.
It fits in a standard electrical panel (9 modules wide on a 17.5 mm module grid) and is built for real boat conditions, including cyclic salt mist and vibration testing. Operating temperature range is -5°C to +45°C.
Key features
- Input power: 12 to 24 V AC (50 to 60 Hz) or 12 to 24 V DC, with SELV output
- 29 V DC BUS output with decoupling coil plus a separate 29 V DC AUX output
- Up to 800 mA total output current for bus powered devices
- 35 mm DIN rail mounting (TH35 / EN 50022) and 9 module width (9 x 17.5 mm)
- Operating temperature range: -5°C to +45°C
- Tested for marine exposure including cyclic salt mist (IEC 60068-2-52) and sinusoidal vibration (IEC 60068-2-6)
Installation and setup
Mount it on a 35 mm DIN rail inside a ventilated cabinet. Keep it in a dry location with no dripping water or spray, and leave clearance around the housing so heat can escape.
For load planning, input draw is 3.5 A at 12 V AC or 2.5 A at 12 V DC, and 2 A at 24 V AC or 1.2 A at 24 V DC. Use those values when sizing upstream wiring and circuit protection.
Electrical and system integration
The BUS output is the 29 V feed with the built-in decoupling coil used on By-me Plus lines. AUX is a second 29 V DC output for auxiliary 29 V loads that belong on the same system.
A single line should not have more than two of these power units connected.
Compatibility and fit
This unit is for installations that need a dedicated 29 V DC supply for Vimar By-me Plus devices and related bus infrastructure. It does not replace your boat’s 12 V or 24 V distribution and should be treated as a separate supply for the automation bus inside the electrical panel.
Good match on board
It suits boats running a centralized By-me Plus setup from a 12 V or 24 V house bank, where the power supply can live in the main electrical locker or a protected helm cabinet rather than in an exposed area.
Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.
