Compact Victron Orion Smart 30 A DC-to-DC battery charger for automatic multi-stage charging of 12 V batteries with Bluetooth and galvanic isolation.

• Automatic battery-to-battery function: charges one 12 V battery/bank from another 12 V source (for example starter to leisure) using intelligent multi-stage algorithms with full overcharge protection.
• Bluetooth connectivity: in-built Bluetooth lets you monitor the charging process and change settings via the VictronConnect app without accessing the installation location.
• Safe unattended charging & continued operation: in-built protection against overload, overheating and overvoltage; the charger will continue to operate at full power while energy is drawn from the battery/load.
• Compatibility & control: suppression filter allows charging from alternators, solar or other DC sources; remote on/off via hard-wired switch, external relay or VictronConnect app; optimised for vehicle battery charging and parallelable for system expansion.
• Galvanic isolation: input, output and case isolated up to 200 Vdc to prevent stray currents to metal boat hulls and reduce interference; LED indicators show target battery charging stage and status.
• DC conversion mode & low-noise output: output stabilised for sensitive DC equipment; output noise 2 mV RMS and minimal ripple.
• Specifications — Input voltage: 8–17 V. Output current: 0–30 A. Battery types: suitable for 12 V lead‑acid or lithium batteries. Under-voltage shutdown/restart: 7.0 V / 7.5 V. Output voltage adjustable range: 10–15 V (12.2 V nominal). Output voltage tolerance: ±0.2 V. Max power consumption: 430 W. Temperature range: −20 to +55 °C. Ambient conditions: max 95% RH, non‑condensing. Cable cross-section: 16 mm² (AWG 6). Dimensions: 130 x 186 x 80 mm (5.12 x 7.32 x 3.15 in). Weight: 1.8 kg (3.97 lb).
• Downloads & support: user manual for 30 A 12 V DC-to-DC isolated battery charger (VOS1212-30I) and datasheet available; consult documentation for installation details and no-load consumption.

Suitable for marine and vehicle installations; follow the manual for correct battery selection, wiring and isolated mounting to maintain galvanic protection.
