Key Features & Technical Specifications

Input & Output

• Nominal input voltage: 12–24 V DC, with an extended range of –25% to +33% (wide-range input)

• Inrush control: Typical inrush current of 1.5 A (I²t ≈ 0.05 A²s), protecting both power rails and upstream protection

• Hold-up time: Approx. 20 ms at 24 V input—great for brief dips or brownouts

• Internal input fuse: 15 A fast-blow, with recommended external protection of 10–16 A

Robust & Efficient Output

• Nominal output: 12 V DC @ 2.5 A (30 W), with an adjustable range from 5 V to 15 V DC

• Boost modes:

  • Static Boost: Up to 3.125 A (≤ 40 °C)

  • Dynamic Boost: Up to 5 A for 4.9 seconds (≤ 60 °C)

• High efficiency: Typically 92.2% at 12 V DC—minimizes waste heat and helps compact panel layouts

• Outstanding reliability: Short-circuit and no-load proof, with thermal derating above 60 °C (2.5%/K)

• Clean & stable output: Ripple < 20 mVpp, control deviation < 1%, < 1 s rise time

• Redundancy ready: Supports both series and parallel configurations for flexible system design

High Reliability & Durability

• Insulation voltage: 2.6 kV DC type-tested, 1.2 kV routine-tested between input/output

• Exceptional MTBF:

  • 2.8 million hours at 25 °C

  • 1.59 million hours at 40 °C

  • 687,000 hours at 60 °C

• Long-life capacitors: Up to 452,000 h at 30 °C; robust across higher temperatures

Compact & Clean Design

• Dimensions: Just 22.5 mm (W) × 106 mm (H) × 90 mm (D)—ultra-slim DIN-rail footprint

• Low heat output: < 0.5 W no-load dissipation; ≤ 2.7 W at nominal load

• Connection flexibility: Push-in terminals accept 0.5 – 2.5 mm² cables; easy wiring; switchable inputs

Visual & Signal Feedback

• LED display:

  • Green when output > 0.9 × U_Set

  • Flashing green when below

  • Yellow when load exceeds threshold (P_Thr)

• Signal output: Configurable digital output: 0 V or 24 V DC (22 mA), default asserts 24 V if output > 0.9 × U_Set
