Read MoreThe Deutronic DVC301 is a galvanically isolated DC/DC converter designed for industrial mobility and vehicle applications. Available in 24V, 48V, and 80V nominal input variants, the DVC301 delivers stable 12.5Vdc or 24Vdc output at up to 300W continuous power with up to 22 A output current, making it suitable for powering control electronics, auxiliary systems, and onboard equipment in harsh environments.
The rugged aluminium enclosure supports contact cooling via the mounting surface for completely fanless operation, and achieves an efficiency of up to 90%. The DVC301 features galvanic isolation of 1.5 kVDC between input and output, reverse polarity awareness, and automatic overtemperature shutdown with self-reset. An extended hold-up time (EUT) variant is also available, incorporating approximately 18,800 µF of output capacitance to bridge voltage dropouts during engine starts.
With an IP67 degree of protection, wide operating temperature range of -30°C to +75°C, and support for parallel and series operation, the DVC301 is engineered for demanding applications in industrial trucks, material handling, and off-highway vehicles.

4x Mounting holes (Ø9 mm) see fig. 8.1 |
| Mounting position | - | Any |
| Cooling | - | A sufficient cooling must be ensured externally in the customer application via the mounting surface. |
| Connection Input / Output | approx. 10 cm cable with 6-pole AMP connector Mate-N-Lok |
See chapter 7 different cable/connector customers request |
| Input Fuse | T10A/250V (@IN 80/48 Vdc) T20A/32V (@IN 36/24 Vdc) T35A/32V (@IN 12 Vdc) |
No integrated input fuse. A fuse must be provided externally by the customer application. |
| Input current limitation | - | Attention: No inrush current limitation in the device. Provide a precharging section in the application, otherwise there is a risk of a overvoltage damage to the input of the DC/DC converter. |
| Reverse polarity protection | - | No reverse polarity protection at the input or output of the device. If the polarity at the input is reversed, the upstream input fuse trips. |
| Parallel operation | Power increase | Connectable in parallel without limitation, no additional control cable needed Smart output regulation for optimized DC current distribution in parallel operation |
| Series operation | Voltage increase | Up to 4 units connectable in series ATTENTION: Follow safety requirements (PELV, SELV) |
