DLoG power supply units can offset voltage drops and extreme peaks.

Our engineers are investing a lot of time in the planning of specifications to allow fail-safe use of the industrial PCs even in the most adverse voltage conditions.

Vehicle-mounted terminals time and again experience voltage drops and extreme peaks due to the on-board voltage of the vehicle . It is therefore important that the terminal can offset these variations. During start-up of, e.g., a diesel-driven forklift, with a nominal on-board voltage of 24V, the on-board network temporarily drops by about 40-50%. Therefore, the power supply units were designed to be able to bridge voltage drops of up to 50% nominally for 20s, or support outages of up to 5ms.

In addition, we test the resilience of the power supply unit in connection with the system in accordance with testing standard EN 61 000-4-4 by using voltage peaks of up to 2KV, thus significantly outperforming the industry's requirements.

Power Supply Units

In the field of mobile and stationary industrial PCs, DLoG is developing their own power supply units in cooperation with leading partners. These units can withstand the most extreme environmental usage conditions while being serviceable.

The technical development of our power supply units focuses on their effectiveness, the electrical and physical detachment of the unit from the terminal, and an extremely high interference resistance with an equally long life span.

• The physical detachment from the mainboard increases serviceability and reduces Total Cost of Ownership (TCO), as in the event of damage, only the power supply unit needs to be replaced rather than the complete mainboard.
• The electrical (galvanic) detachment ensures that there is no electrical connection with the terminal, so no equalizing currents are running.
• Our power supply units reach an effectiveness of up to 90%.
• The calculated life span of our power supply units averages 10 years of uninterrupted service.
  Field failure rate is below 0.5%.
• All DLoG power supply units are designed to be permanently short-circuit-proof and idle-operation-proof.
• Our power supply units are developed to provide inverse-polarity protection and inrush current suppression.
• DLoG power supply units are certified and licensed for temperature ranges of between -30°C to +70°C.
